    Before TARANTO, WALLACH, * and CHEN, Circuit Judges.
    Opinion for the court filed by Circuit Judge TARANTO.
    Opinion concurring in the result filed by Circuit Judge
    WALLACH.
    TARANTO, Circuit Judge.
    On December 26, 2018, the U.S. Department of Justice,
    exercising congressionally granted authority to implement
    various federal firearms statutes, promulgated a rule that
    is the basis for the takings claim in this case. Bump-Stock-
    Type Devices, 
    83 Fed. Reg. 66,514
     (Dec. 26, 2018) (Final
    Rule). The impetus for the proceeding was the massacre in
    Las Vegas on October 1, 2017, when a lone shooter, using
    “rifles with attached bump-stock-type devices,” fired “sev-
    eral hundred rounds of ammunition in a short period of
    time, killing 58 people and wounding approximately 500.”
    
    Id. at 66,516
    . Since 1986, 
    18 U.S.C. § 922
    (o) has declared
    it to be unlawful to possess or transfer a “machinegun”
    (with exceptions not applicable here, for governments and
    for lawful possession before the 1986 law took effect), with
    “machinegun” defined with specificity by statute, 
    26 U.S.C. § 5845
    (b) (incorporated by 
    18 U.S.C. § 921
    (a)(23)). In the
    Final Rule, the Department, which houses the Bureau of
    Alcohol, Tobacco, Firearms and Explosives (ATF), adopted
    regulations that interpret the statutory definition and spe-
    cifically provide that the definition includes “a bump-stock-
    type device, i.e., a device that allows a semi-automatic fire-
    arm to shoot more than one shot with a single pull of the
    trigger by harnessing the recoil energy of the semi-auto-
    matic firearm to which it is affixed so that the trigger resets
    and continues firing without additional physical manipula-
    tion of the trigger by the shooter.” 83 Fed. Reg. at 66,553–
    54. The Final Rule states that “[t]he bump-stock-type
    *Circuit Judge Evan J. Wallach assumed senior sta-
    tus on May 31, 2021.

    devices covered by this final rule were not in existence prior
    to” 
    18 U.S.C. § 922
    (o). 
    Id. at 66,514
    . As of March 26, 2019,
    the Rule’s effective date, possessors of such devices had to
    destroy them or abandon them to ATF, or else face criminal
    penalties under 
    18 U.S.C. § 924
    (a)(2) for a “knowing” vio-
    lation of 
    18 U.S.C. § 922
    (o). See 
    id. at 66,514, 66,520, 66,523
    .
    Plaintiffs Roy McCutchen and Paducah Shooter’s Sup-
    ply, Inc. brought this action against the United States in
    the Court of Federal Claims (Claims Court) under the
    Tucker Act, 
    28 U.S.C. § 1491
    . Asserting that the Final
    Rule effected a taking for public use of their bump-stock-
    type devices by requiring the devices’ destruction or sur-
    render to ATF, plaintiffs seek just compensation under the
    Fifth Amendment’s Takings Clause. Because it is the Final
    Rule that plaintiffs challenge and “[t]he bump-stock-type
    devices covered by this final rule were not in existence prior
    to the effective date of” 
    18 U.S.C. § 922
    (o), 83 Fed. Reg. at
    66,514, plaintiffs’ bump-stock-type devices necessarily
    were not in existence before § 922(o) took effect. Although
    the Rule’s validity has been disputed in other cases, plain-
    tiffs accept, in their pursuit of their compensation claim,
    that the Final Rule is an authorized and lawful (i.e., valid)
    implementation of the statutory bar on possession or trans-
    fer of a “machinegun.”
    The government moved to dismiss the claim under
    Court of Federal Claims Rule 12(b)(6). By the time the mo-
    tion was fully briefed, the Rule’s effective date had arrived,
    and plaintiffs had complied with the Rule and destroyed
    their bump-stock-type devices. The Claims Court granted
    the motion and dismissed the takings claim. It principally
    relied on the “police power” doctrine, concluding that, be-
    cause the Final Rule sought to protect health and safety, it
    did not effect a taking for public use. See McCutchen v.
    United States, 
    145 Fed. Cl. 42
    , 51–53 (2019).

    We affirm, but we do so on a threshold ground different
    from, though related to, the Claims Court’s grounds. The
    interest that plaintiffs allege was taken was the interest in
    continued possession or transferability of their devices.
    The takings claim depends on plaintiffs having an estab-
    lished property right in continued possession or transfera-
    bility even against a valid agency implementation of the
    preexisting statutory bar on possession or transfer. But
    plaintiffs’ title, which we assume is otherwise valid under
    state law, was always inherently limited by 
    18 U.S.C. § 922
    (o), a very specific statutory prohibition on possession
    and transfer of certain devices defined in terms of physical
    operation, together with a congressional authorization of a
    (here undisputedly) valid agency interpretation of that pro-
    hibition. That title-inhering limit means that plaintiffs
    lacked an established property right in continued posses-
    sion or transferability. The takings claim therefore fails.
    I
    A
    In 1934, Congress enacted the National Firearms Act,
    Pub. L. No. 73–474, 
    48 Stat. 1236
     (NFA or 1934 Act). The
    Act regulated the importation, manufacture, transfer, sale,
    and possession of certain firearms, including “ma-
    chineguns.” 1 See 
    26 U.S.C. § 5801
     et seq. Congress specif-
    ically defined “machinegun.”       
    Id.
     § 5845(b) (current
    version, quoted infra). Congress included penalty and for-
    feiture provisions and also subjected violators to the gen-
    eral enforcement measures available under the internal-
    revenue laws. Id. §§ 5871–72.
    About thirty years later, Congress enacted the Gun
    Control Act of 1968, Pub. L. No. 90–618, 
    82 Stat. 1213
    1  Statutory and regulatory provisions sometimes use
    “machinegun,” sometimes “machine gun.” Except when
    quoting, we use the latter.

    MCCUTCHEN   v. UNITED STATES                               5
    (GCA or 1968 Act). See 
    18 U.S.C. § 921
     et seq. In that Act,
    Congress established a regulatory licensing scheme and
    imposed criminal prohibitions on certain firearm transac-
    tions. 
    18 U.S.C. § 923
    . The GCA incorporates the National
    Firearm Act’s “machinegun” definition. 
    Id.
     § 921(a)(23)
    (“The term ‘machinegun’ has the meaning given such term
    in section 5845(b) of the National Firearms Act (26 U.S.C.
    5845(b)).”).
    In 1986, Congress adopted the Firearm Owners’ Pro-
    tection Act, Pub. L. No. 99–308, 
    100 Stat. 449
     (FOPA or
    1986 Act), which amended the Gun Control Act and Na-
    tional Firearm Act. The 1986 Act added 
    18 U.S.C. § 922
    (o),
    which provided when enacted and still provides:
    (o)(1) Except as provided in paragraph (2), it shall
    be unlawful for any person to transfer or possess a
    machinegun.
    (2) This subsection does not apply with respect to—
    (A) a transfer to or by, or possession by or
    under the authority of, the United States or
    any department or agency thereof or a
    State, or a department, agency, or political
    subdivision thereof; or
    (B) any lawful transfer or lawful possession
    of a machinegun that was lawfully pos-
    sessed before the date this subsection takes
    effect [May 19, 1986].
    § 102, 100 Stat. at 453; 
    18 U.S.C. § 922
    (o). That language
    makes it unlawful to possess or transfer a “machinegun,”
    with exceptions for governments and pre-FOPA lawful pos-
    session. See Final Rule, 83 Fed. Reg. at 66,515 (noting that
    the amendment “effectively froze the number of legally
    transferrable machineguns to those that were registered
    before the effective date of the statute”). A “knowing” vio-
    lation subjects the violator to criminal penalties, 18 U.S.C.

    § 924(a)(2); a “willful” violation subjects the violator to “sei-
    zure and forfeiture” remedies, id. § 924(d)(1).
    The crucial term, “machinegun,” is declared, in 
    18 U.S.C. § 921
    (a)(23), to have the meaning specified in 
    26 U.S.C. § 5845
    (b). Since 1986, that definition has provided:
    The term “machinegun” means any weapon which
    shoots, is designed to shoot, or can be readily re-
    stored to shoot, automatically more than one shot,
    without manual reloading, by a single function of
    the trigger. The term shall also include the frame
    or receiver of any such weapon, any part designed
    and intended solely and exclusively, or combination
    of parts designed and intended, for use in convert-
    ing a weapon into a machinegun, and any combina-
    tion of parts from which a machinegun can be
    assembled if such parts are in the possession or un-
    der the control of a person.
    
    26 U.S.C. § 5845
    (b) (emphases added). 2
    2   The italicized phrase, “any part designed . . . ,” was
    substituted in 1986 for the phrase, “any combination of
    parts designed and intended for use in converting a weapon
    into a machinegun.” 1986 Act, § 109(a), 100 Stat. at 460.
    The 1968 Act enacted the following version of 
    26 U.S.C. § 5845
    (b): “(b) MACHINEGUN.—The term ‘machinegun’
    means any weapon which shoots, is designed to shoot, or
    can be readily restored to shoot, automatically more than
    one shot, without manual reloading, by a single function of
    the trigger. The term shall also include the frame or re-
    ceiver of any such weapon, any combination of parts de-
    signed and intended for use in converting a weapon into a
    machinegun, and any combination of parts from which a
    machinegun can be assembled if such parts are in the pos-
    session or under the control of a person.” § 201, 82 Stat. at
    1231.

    In 
    18 U.S.C. § 926
    (a), Congress has granted the Attor-
    ney General the authority to promulgate rules and regula-
    tions “necessary to carry out” chapter 44 of Title 18, U.S.
    Code, which includes 
    18 U.S.C. § 922
    . In 
    26 U.S.C. § 7801
    (a), Congress has made the Attorney General re-
    sponsible for the “administration and enforcement” of
    chapter 53 of Title 26, U.S. Code, which includes 
    26 U.S.C. § 5845
    . The grants of implementation authority have been
    in place since 1986: The current “necessary to carry out”
    language of 
    18 U.S.C. § 926
    (a) was adopted in the 1986 Act,
    replacing the preexisting “reasonably necessary” authority,
    § 106, 100 Stat. at 459; and even before the 1986 Act, 
    26 U.S.C. § 7801
    (a) granted the Executive the “administration
    and enforcement” authority relevant here, 
    26 U.S.C. § 7801
    (a) (1982). Before 2002, both authorities resided
    with the Secretary of the Treasury, see 
    18 U.S.C. §§ 921
    (a)(18), 926(a) (2000); 
    26 U.S.C. § 7801
    (a) (2000), but
    in 2002, they were transferred to the Attorney General as
    part of the relocation of ATF to the Department of Justice,
    see Homeland Security Act of 2002, Pub. L. No. 107–296,
    § 1111, 
    116 Stat. 2135
    , 2274–75; 28 U.S.C. § 599A(c)(1).

    ATF.

    A rifle is semiautomatic if, after it has been fired,
    rechambering of ammunition is automatic but refiring is
    not. Specifically, “[t]he term ‘semiautomatic rifle’ means
    any repeating rifle which utilizes a portion of the energy of
    a firing cartridge to extract the fired cartridge case and
    chamber the next round, and which requires a separate
    The 1934 Act’s original definition reads: “The term ‘ma-
    chine gun’ means any weapon which shoots, or is designed
    to shoot, automatically or semiautomatically, more than
    one shot, without manual reloading, by a single function of
    the trigger.” § 1(b), 48 Stat. at 1236.
    Case: 20-1188    Document: 44      Page: 8    Filed: 10/01/2021
    8                              MCCUTCHEN    v. UNITED STATES
    pull of the trigger to fire each cartridge.” 
    18 U.S.C. § 921
    (a)(28). A “bump-stock-type device” transforms a
    semiautomatic rifle so that “a separate pull of the trigger
    to fire each cartridge” is not needed. Such a device replaces
    the generally stationary stock resting against the shooter’s
    shoulder with a sliding stock that lets the shooter substan-
    tially increase the rate of fire without a commensurate in-
    crease in the number of finger motions pulling the trigger.
    Final Rule, 83 Fed. Reg. at 66,516. The device channels
    and directs the recoil energy from each shot “into the space
    created by the sliding stock (approximately 1.5 inches) in
    constrained linear rearward and forward paths.” Id. at
    66,518. By maintaining constant backward pressure on
    the trigger (without repeated finger motions to pull the
    trigger) and constant forward pressure on the front of the
    gun, a shooter can fire bullets continuously and at a high
    rate to “mimic” the performance of a fully automatic
    weapon. Id. at 66,516.
    A variety of devices with different mechanisms for us-
    ing the firearm’s recoil energy to refire without a new
    movement of the finger (a separate new pull motion of the
    finger) came to ATF’s attention long before the proceeding
    that ended with the Final Rule. In 2002, ATF “initially re-
    viewed the Akins Accelerator.” Id. at 66,517. Unlike the
    devices at issue here, the Akins Accelerator used springs to
    cause the trigger to continue to make contact with the
    shooter’s finger rather than relying on the shooter to main-
    tain pressure on the trigger and the firearm. See id. at
    66,514, 66,516–17; see also Akins v. United States, 312 F.
    App’x 197, 200 (11th Cir. 2009) (“After a single application
    of the trigger by a gunman, the Accelerator uses its inter-
    nal spring and the force of recoil to fire continuously the
    rifle cradled inside until the gunman releases the trigger
    or the ammunition is exhausted.”).
    Initially, in 2002, ATF determined that the device was
    not a machine gun “because ATF interpreted the statutory
    term ‘single function of the trigger’ to refer to a single
    Case: 20-1188    Document: 44      Page: 9    Filed: 10/01/2021
    MCCUTCHEN   v. UNITED STATES                               9
    movement of the trigger.” Final Rule, 83 Fed. Reg. at
    66,517 (emphases added). But in 2006, ATF reversed
    course in a published ruling. See ATF Ruling 2006-2. After
    retesting the Akins Accelerator, ATF determined that with
    the device, “a single pull of the trigger initiates an auto-
    matic firing cycle [that] continues until the finger is re-
    leased or the ammunition supply is exhausted.” Id. at 2.
    This time ATF interpreted the statutory phrase “single
    function of the trigger” as “single pull of the trigger.” Id.
    (emphases added). Given that interpretation, ATF readily
    determined that the Akins Accelerator was a machine gun
    under the NFA and GCA. Id. at 2–3. When Akins chal-
    lenged ATF’s determination in federal court, the Eleventh
    Circuit, agreeing with the district court, affirmed ATF’s
    statutory interpretation and consequent determination
    that the Akins Accelerator was a machine gun. Akins, 312
    F. App’x at 199–201; Akins v. United States, No. 8:08-cv-
    988-T-26TGW, 
    2008 WL 11455059
    , at *3–8 (M.D. Fla. Sept.
    23, 2008).
    Thereafter, ATF considered other bump-stock-type de-
    vices. As ATF later described its actions, ATF advised that
    a number of such devices were not machine guns—includ-
    ing the ones at issue here. See Final Rule, 83 Fed. Reg. at
    66,517. Specifically, in ten unpublished classification rul-
    ings between 2008 and 2017, ATF “provided different ex-
    planations for why certain bump-stock-type devices were
    not machineguns, but none of them extensively examined
    the meaning of ‘automatically.’” Id. at 66,518. All those
    decisions were subject to ATF’s publicly available hand-
    book warning that such rulings could not be relied upon as
    guaranteeing inapplicability of the existing statutory pro-
    hibitions if reconsidered and modified. See National Fire-
    arms Act Handbook § 7.2.4.1 (Handbook) (relevant
    portions have stayed the same from at least 2007 to now).
    Indeed, the Eleventh Circuit relied on ATF’s power to “re-
    consider and rectify” a classification decision when uphold-
    ing ATF’s 2006 ruling on the Akins Accelerator after ATF’s
    Case: 20-1188    Document: 44      Page: 10    Filed: 10/01/2021
    10                               MCCUTCHEN   v. UNITED STATES
    contrary 2002 ruling. See Akins, 312 F. App’x at 200
    (“Based on the operation of the Accelerator, the Bureau had
    authority to ‘reconsider and rectify’ what it considered to
    be a classification error.”).
    C
    Within a few months of the October 1, 2017 massacre
    in Las Vegas, reconsideration of bump-stock-type devices
    began. The Department of Justice issued an Advanced No-
    tice of Proposed Rulemaking on December 26, 2017, to get
    “information and comments from the public and industry
    regarding the nature and scope of the market for” “certain
    devices, commonly known as ‘bump fire’ stocks.” Applica-
    tion of the Definition of Machinegun to “Bump Fire” Stocks
    and Other Similar Devices, 
    82 Fed. Reg. 60,929
    , 60,929
    (Dec. 26, 2017). About two months later, the President “di-
    rect[ed] the Department of Justice to dedicate all available
    resources . . . as expeditiously as possible, to propose for
    notice and comment a rule banning all devices that turn
    legal weapons into machineguns.” Application of the Defi-
    nition of Machinegun to “Bump Fire” Stocks and Other
    Similar Devices, 
    83 Fed. Reg. 7,949
    , 7,949 (Feb. 20, 2018).
    Nearly a month after that, the Department issued a
    Notice of Proposed Rulemaking that sought “to clarify that
    [bump-stock-type devices] are ‘machineguns.’” See Bump-
    Stock-Type Devices, 
    83 Fed. Reg. 13,442
    , 13,442 (Mar. 29,
    2018). On December 26, 2018, the Department completed
    its process of “reexamining” its 2008–17 decisions and is-
    sued the Final Rule, which adopted new regulations, with
    an effective date of March 26, 2019. 83 Fed. Reg. at 66,514,
    66,520–21, 66,553–54.
    The regulations specifically interpret one phrase and
    one term in the detailed statutory definition of “ma-
    chinegun.” Id. at 66,553–54; see also 
    27 C.F.R. §§ 447.11
    ,
    478.11, 479.11. Thus, codifying the 2006 definition from
    the Akins Accelerator proceeding, the regulations define

    of the trigger and analogous motions.” 83 Fed. Reg. at
    66,553–54. The regulations also newly define the term “au-
    tomatically”—to mean “functioning as the result of a self-
    acting or self-regulating mechanism that allows the firing
    of multiple rounds through a single function of the trigger.”
    Id. at 66,553. The regulations also make clear that, under
    those definitions, bump-stock-type devices, as specifically
    defined in the regulations (quoted supra), are “ma-
    chineguns.” Id. at 66,553–54. The Department explained
    that the two adopted definitions were the “best interpreta-
    tion” of the statutory definition of “machinegun.” Id. at
    66,514, 66,517–18, 66,521. It added that, although the “fi-
    nal rule reflects the public safety goals of the NFA and
    GCA,” id. at 66,522, “[t]he bump-stock-type device rule is
    not a discretionary policy decision based upon a myriad of
    factors that the agency must weigh, but is instead based
    only upon the functioning of the device and the application
    of the relevant statutory definition,” id. at 66,529.
    The Final Rule’s consequence was that individuals
    would be subject to “criminal liability only for possessing
    bump-stock-type devices after the effective date of [this]
    regulation”—March 26, 2019. Id. at 66,514, 66,525; see
    also, e.g., id. at 66,525 (“The rule would criminalize only
    future conduct, not past possession of bump-stock-type de-
    vices that ceases by the effective date of this rule.”). To
    avoid liability, possessors of bump-stock-type devices had
    to destroy their devices or abandon them at an ATF office
    by March 26, 2019. Id. at 66,549 (describing “[d]isposal”
    options); see also, e.g., id. at 66,514–15, 66,530, 66,539,

    II
    On December 26, 2018, plaintiffs sued the United
    States in the Claims Court. See J.A. 22–30 (Complaint). 3
    McCutchen and Paducah possessed bump-stock-type de-
    vices before the publication of the Rule and destroyed those
    devices before the Rule’s effective date. J.A. 23–24, ¶¶ 10–
    11; McCutchen, 145 Fed. Cl. at 45 (citing ECF No. 12).
    The government moved to dismiss the complaint for
    failure to state a claim under Rule 12(b)(6), and the Claims
    Court granted the motion. See McCutchen, 145 Fed. Cl. at
    45. In reaching that result, the court determined that the
    Final Rule did not effect a taking for public use because
    ATF acted “pursuant to its police power.” Id. at 51. The
    Claims Court also concluded that plaintiffs’ claim of a phys-
    ical taking failed because the term “take[]” does not cover
    a regulation compelling dispossession of property by re-
    quiring the owner to destroy the property (or else surren-
    der it to the government) and that plaintiffs’ alternative
    claim of total elimination of value failed because personal
    (not real) property is “subject to pervasive government reg-
    ulation.” Id. at 53–55. Finally, the court determined that
    plaintiffs “waived” any argument for a taking under the
    flexible takings standard governing use restrictions and, in
    any event, could not show such a taking. Id. at 55–57.
    Plaintiffs timely appealed. We have jurisdiction under
    
    28 U.S.C. § 1295
    (a)(3).

    Rule 12(b)(6) without ruling on class certification.

    , 570 (2007)). We may con-
    sider “documents incorporated into the complaint by refer-
    ence, and matters of which a court may take judicial
    notice.” Tellabs, Inc. v. Makor Issues & Rights, Ltd.,

    question of law based on factual underpinnings.” Caquelin

    The Takings Clause of the Fifth Amendment provides
    that “private property [shall not] be taken for public use,
    without just compensation.” U.S. Const. amend. V. Tak-
    ings have been classified in various ways. For example,
    some involve “physical appropriations” and some “use re-
    strictions.” Cedar Point Nursery v. Hassid, 
    141 S. Ct. 2063
    ,
    2071–72 (2021). Categorical rules have generally applied
    to the former category. 
    Id. at 2071
    . Use restrictions gen-
    erally are subject to the “flexible test developed in [Penn
    Central Transportation Co. v. City of New York, 
    438 U.S. 104
     (1978)],” see Cedar Point, 141 S. Ct. at 2072, although
    use restrictions that deprive a landowner of “all economi-
    cally beneficial or productive use of land” have been
    deemed a categorical taking, Lucas v. S.C. Coastal Council,
    
    505 U.S. 1003
    , 1015, 1019 (1992). On appeal, plaintiffs
    pursue only physical-appropriation and Lucas categorical-
    taking contentions. See McCutchen Opening Br. at 34–39,
    39 n.9 (not making Penn Central contention).
    We do not reach the grounds on which the Claims
    Court relied. In particular, we do not decide under what
    circumstances a measure that newly bars possession of per-
    sonal property (as opposed to restricting a use of property)
    and that serves a “police power” purpose (and is constitu-
    tionally authorized for the federal government) is not a
    Case: 20-1188    Document: 44      Page: 14     Filed: 10/01/2021
    14                              MCCUTCHEN    v. UNITED STATES
    “taking,” and thus requires no compensation. 4 Nor do we
    decide whether mandating permanent dispossession by or-
    dering destruction of personal property cannot be a “phys-
    ical taking,” even if the government-specified alternative to
    destruction is surrender to the government and the man-
    date is backed by government remedies of seizure and for-
    feiture for a willful violation as well as criminal remedies
    for a knowing violation.
    We do not resolve substantial questions raised by those
    issues. For example, the Supreme Court has said that the
    Takings Clause both bars takings that are not for a “public
    use” and requires payment for takings that are for such a
    use, see Kelo v. City of New London, 
    545 U.S. 469
    , 480
    (2005); Hawaii Housing Authority v. Midkiff, 
    467 U.S. 229
    ,
    240 (1984), and it has also said that “[t]he ‘public use’ re-
    quirement is . . . coterminous with the scope of a sover-
    eign’s police powers,” Midkiff, 
    467 U.S. at 240
    ; see also
    Ruckelshaus v. Monsanto Co., 
    467 U.S. 986
    , 1014 (1984).
    Under those premises, the question arises: If a “police
    power” justification for a measure means that there is no
    taking, what government acts would fall into the category
    of takings that the Clause permits (because the act is for a
    “public use,” i.e., within the “sovereign’s police powers”) but
    only upon payment of just compensation? And if the “police
    power” doctrine is to be cabined to some subset of police
    powers, as the Claims Court suggested might be necessary,
    4  We have recognized that a “police power” rationale,
    where the federal government is concerned, must be con-
    sidered within the context of constitutional authorization
    of particular powers. See, e.g., Rose Acre Farms, Inc. v.
    United States, 
    373 F.3d 1177
    , 1191–92 & n.10 (Fed. Cir.
    2004); Florida Rock Indus., Inc. v. United States, 
    18 F.3d 1560
    , 1568 n.17 (Fed. Cir. 1994); Allied-Gen. Nuclear
    Servs. v. United States, 
    839 F.2d 1572
    , 1576 (Fed. Cir.
    1988).

    MCCUTCHEN   v. UNITED STATES                             15
    145 Fed. Cl. at 51, and the government suggested at oral
    argument, Oral Arg. at 48:42–52:53 (referring without def-
    inition to “core police powers”), the questions arise: What
    would that cabining be, what ground would it rest on, and
    how would it address recognized challenges, among them
    challenges of workable line-drawing? See Lucas, 
    505 U.S. at 1024, 1026
    ; Midkiff, 
    467 U.S. at
    239–40.
    These and other questions would be unavoidable were
    we to address the Claims Court’s rationales. We have no
    precedent that is so on point—involving facts and holdings
    so close to those presented here—that we could justifiably
    apply the rationales without extensive exploration of the
    doctrinal issues. Notably, the main authorities from this
    court relied on by the Claims Court for its police-power
    analysis involved government dispossessions of personal
    property that rested on specific government authority that
    long predated the possession of the personal property at is-
    sue. See, e.g., Kam-Almaz v. United States, 
    682 F.3d 1364
    ,
    1372 (Fed. Cir. 2012) (evidentiary seizure at airport upon
    entry from overseas, exercising the “government’s power to
    police the border”); AmeriSource Corp. v. United States,
    
    525 F.3d 1149
    , 1150, 1153 (Fed. Cir. 2008) (seizure of drugs
    for use in criminal prosecutions); Acadia Tech., Inc. v.
    United States, 
    458 F.3d 1327
    , 1328–29 (Fed. Cir. 2006) (sei-
    zure and forfeiture of goods entering country with counter-
    feit trademarks). Reviewing the Claims Court’s rationales
    would call for extensive analysis to decide how far beyond
    such circumstances a “police power” rationale properly ap-
    plies and whether it properly reaches this case. Cf. Cedar
    Point, 141 S. Ct. at 2079 (discussing “longstanding back-
    ground restrictions on property rights” including “back-
    ground limitations” of “traditional common law
    privileges”).
    We resolve the case on a threshold ground that differs
    from, though is related to, the Claims Court’s grounds—
    one that involves the preexisting-law circumstance that
    was present in the just-cited cases. Plaintiffs’ takings

    have “established a property interest for purposes of the
    Fifth Amendment” against the government action.

    , 715 (2010)
    (plurality) (“If a legislature or a court declares that what
    was once an established right of private property no longer
    exists, it has taken that property, no less than if the State
    had physically appropriated it or destroyed its value by
    regulation.” (second emphasis added)). “[T]o have a cause
    of action for a Fifth Amendment taking, the plaintiff must
    point to a protectable property interest that is asserted to
    be the subject of the taking.” Palmyra Pacific Seafoods,

    takings case bears the burden to demonstrate a protectable
    property interest.”); American Bankers Ass’n v. United
    States,

    tion.”); Alimanestianu v. United States,

    987 F.3d 1063
    , 1068 (Fed. Cir. 2021). 5
    5   Unlike Judge Wallach, we see no basis for limiting
    this general threshold aspect of takings analysis, concern-
    ing the property right alleged to have been taken, to the
    particular type of government activity—a land-use re-
    striction that deprives a landowner of all economically ben-
    eficial or productive use of the land—that was at issue in
    Lucas.

    As explained next, we conclude that, given the preex-
    isting federal statutory prohibition on possession or trans-
    fer of “machineguns,” 
    18 U.S.C. § 922
    (o), subject to a valid
    implementation by the Attorney General, plaintiffs lacked
    a property right in what they allege was taken—continued
    possession or transferability of their bump-stock-type de-
    vices.
    B
    “[P]roperty interests . . . are created and their dimen-
    sions are defined by existing rules or understandings that
    stem from an independent source.” Ruckelshaus, 467 U.S.
    at 1001 (cleaned up); see also Phillips v. Washington Legal
    Found., 
    524 U.S. 156
    , 164 (1998) (similar). Here, we as-
    sume that, as a matter of state law standing alone, plain-
    tiffs had property rights in the personal property at issue.
    But “the government does not take a property interest
    when it merely asserts a ‘pre-existing limitation upon the
    [property] owner’s title.’” Cedar Point, 141 S. Ct. at 2079
    (quoting Lucas, 
    505 U.S. at
    1028–29). As we have ex-
    plained, “[t]he Supreme Court in Lucas made clear that
    property interests are acquired subject to ‘background
    principles’ of law, and that limitations on property rights
    that otherwise would effect a categorical taking are permis-
    sible if they ‘inhere in the title itself.’” Bair v. United
    States, 
    515 F.3d 1323
    , 1327 (Fed. Cir. 2008) (quoting Lucas,
    
    505 U.S. at 1029
    ); see also A & D Auto Sales, Inc. v. United
    States, 
    748 F.3d 1142
    , 1152–53 (Fed. Cir. 2014) (explaining
    the principle). And valid preexisting federal-law limita-
    tions on what otherwise would be state-law property rights
    are among the limitations that may inhere in title so as to
    limit compensable property rights. See Bair, 
    515 F.3d at 1329
     (explaining that “a federal statute or authority can
    constitute a ‘background principle’ that inheres in the title
    to property interests arising after its enactment, therefore
    precluding a takings claim based on the application of the
    statute to those property interests”); see also Dames &
    Moore v. Regan, 
    453 U.S. 654
    , 674 n.6 (1981) (rejecting
    Case: 20-1188     Document: 44      Page: 18     Filed: 10/01/2021

    takings claim on this basis); cf. Columbus Reg’l Hosp. v.
    United States, 
    990 F.3d 1330
    , 1349 (Fed. Cir. 2021) (reject-
    ing exaction claim for lack of protected property interest
    based on Dames & Moore and American Bankers Ass’n).
    In this case, the federal-law prohibition on possession
    and transfer, together with a congressional grant of imple-
    mentation authority, predated the existence, let alone
    plaintiffs’ possession, of the bump-stock-type devices that
    plaintiffs were compelled to destroy or surrender. 6 That
    prohibition is a very specific one, defined in terms of the
    physical operation of particular devices, not in terms
    simply of a broadly stated goal. The latter situation raises
    issues not presented here. See Preseault v. United States,
    
    100 F.3d 1525
    , 1537–38 (Fed. Cir. 1996) (en banc); see also
    Bair, 
    515 F.3d at 1330
     (explaining this court’s Preseault
    conclusion that “broad general legislation authorizing a
    federal agency to engage in future regulatory activity, did
    not effectively limit the property right” (cleaned up)). And
    the Final Rule is an interpretation of the text of that spe-
    cific statutory prohibition (in context, of course), not an ex-
    ercise of discretion to act in pursuit of a broadly stated
    statutory goal.
    Moreover, plaintiffs accept that the Final Rule’s imple-
    mentation of the preexisting prohibition is an authorized
    and legally valid interpretation of the statutory prohibi-
    tion, making no argument to the contrary. For that reason,
    and in light of our precedents, we accept that premise. See
    Rith Energy, Inc. v. United States, 
    270 F.3d 1347
    , 1352
    (Fed. Cir. 2001) (“[I]n a takings case we assume that the
    underlying governmental action was lawful . . . .”); Rith
    6   In at least this respect, the present case differs crit-
    ically from Maryland Shall Issue, Inc. v. Hogan, 
    963 F.3d 356
     (4th Cir. 2020), which involved a state law enacted af-
    ter the creation and acquisition of the property at issue
    (there, bump-stock-type devices as well).

    , 1476 (Fed. Cir. 1997).
    The accepted validity of the Final Rule as an interpre-
    tation of the preexisting statutory prohibition on posses-
    sion and transfer must, at least in this case, rest on one of
    three premises: (1) the interpretive-deference doctrine of
    Chevron, U.S.A., Inc. v. Natural Resources Defense Council,
    Inc., 
    467 U.S. 837
     (1984), is inapplicable, and the Final
    Rule is valid as the best interpretation of the statutory pro-
    hibition; (2) Chevron applies and the Final Rule is valid at
    Step 1, so that the statutory prohibition unambiguously re-
    quires the interpretation articulated in the Final Rule; or
    (3) Chevron applies and the Final Rule is valid at Step 2,
    so that it is (merely) one reasonable interpretation of the
    statutory prohibition. We do not decide which possibility
    would govern in a determination of the validity of the Final
    Rule (which we assume); in particular, we do not decide
    whether 
    18 U.S.C. § 922
    (o), to which criminal penalties ap-
    ply if the violation is knowing, is subject to Chevron. Under
    any of these three possibilities, we hold, based on the preex-
    isting federal law, that plaintiffs lack a property right in
    continued possession or transferability of the devices at is-
    sue. We first address the legal bases for so concluding and
    then explain why, in this case, the ATF classification rul-
    ings between 2008 and 2017 do not support a different con-
    clusion.

    The analysis of the first two possibilities is particularly
    simple. If Chevron is inapplicable, validity entails that the
    Final Rule’s interpretation is the “best interpretation” of 
    18 U.S.C. § 922
    (o), with its incorporated “machinegun” term,
    as defined in 
    26 U.S.C. § 5845
    (b). See Chudik v. Hirshfeld,
    
    987 F.3d 1033
    , 1039 (Fed. Cir. 2021) (“Where the Chevron
    framework is inapplicable, we determine the best interpre-
    tation of the statute for ourselves, while giving the agency’s
    position such weight as warranted under [Skidmore v.
    Swift & Co., 
    323 U.S. 134
    , 139–40 (1944)].” (citations and
    internal quotation marks omitted)). Similarly, if Chevron
    applies but validity is resolved at Chevron Step 1, then va-
    lidity entails that the Final Rule’s interpretation is the un-
    ambiguous meaning of 
    18 U.S.C. § 922
    (o). In either event,
    the preexisting statute itself, properly understood, barred
    the possession or transfer at issue. In these circumstances,
    the bar always limited plaintiffs’ title, and plaintiffs never
    had a property right against government assertion of the
    duty to destroy the devices at issue or surrender them. See
    Hurtado v. United States, 
    410 U.S. 578
    , 588 (1973) (“[T]he
    Fifth Amendment does not require that the Government
    pay for the performance of a public duty it is already
    owed.”). 7
    7  We do not consider whether, and if so when, it could
    make a difference if, before a plaintiff’s possession, some
    courts had actually, though incorrectly, adjudicated the
    relevant property to be outside a statutory prohibition on
    possession. No such adjudication took place with respect
    to plaintiffs’ bump-stock-type devices. Relatedly, and rele-
    vant to the third possibility (Chevron Step 2) discussed
    next, there was no authoritative judicial adoption of a con-
    trary meaning from which the agency departed in the Final
    Rule. See Nat’l Cable & Telecomms. Ass’n v. Brand X In-
    ternet Servs., 
    545 U.S. 967
    , 982 (2005) (holding that an
    Case: 20-1188    Document: 44      Page: 21    Filed: 10/01/2021
    MCCUTCHEN   v. UNITED STATES                               21
    The remaining possibility for the validity of the Final
    Rule’s interpretation—that Chevron applies and the inter-
    pretation is valid only at Chevron Step 2—requires some-
    what more analysis, but the conclusion is the same. The
    additional element is the pair of preexisting statutory
    grants of implementation authority to the Executive. 
    18 U.S.C. § 926
    (a) (authority to adopt rules “necessary to
    carry out” the provisions of chapter 44 of Title 18, U.S.
    Code, including 
    18 U.S.C. § 922
    (o)); 
    26 U.S.C. § 7801
    (a)
    (authority over “administration and enforcement” of chap-
    ter 53 of Title 26, U.S. Code, including 
    26 U.S.C. § 5845
    (b)).
    For plaintiffs here, the preexisting limitation on their title
    included subjection to future valid agency interpretations
    of the possession-and-transfer prohibition (as assumed
    here) adopted in the exercise of that authority. In these
    circumstances, plaintiffs had no property interest pro-
    tected by the compensation requirement of the Takings
    Clause against such a valid interpretation when adopted.
    By 1986, the Supreme Court’s 1984 decision in Chevron
    already made clear that the law, for a statute like 
    18 U.S.C. § 922
    (o), included the possibility of reasonable resolutions
    of ambiguities. For the title-limiting § 922(o) in particular,
    the choices were limited as relevant here—focused over-
    whelmingly, though not exclusively, on whether 
    26 U.S.C. § 5845
    (b)’s “single function of the trigger” language, in con-
    text, could be understood to mean a single volitional finger
    movement of the shooter (which could produce multiple fir-
    ings if recoil energy were captured). We cannot say that
    plaintiffs had “an established right of private property,”
    Stop the Beach, 
    560 U.S. at 715
     (plurality), in the possibil-
    ity that the agency would adopt one rather than another of
    the limited range of interpretations (both reasonable, by
    agency may depart from a prior judicial interpretation that
    adopted the best reading of a statute but did not find that
    reading to be the unambiguous meaning of the statute).

    assumption) relevant here. Cf. Murr v. Wisconsin, 
    137 S. Ct. 1933
    , 1950 (2017) (Roberts, C.J., dissenting) (reasoning
    that the Takings Clause protects owners of “established
    property rights”). We have no basis for deeming any inter-
    est in either possibility a “recognized property interest” re-
    quired for a takings claim. Skip Kirchdorfer, Inc. v. United
    States, 
    6 F.3d 1573
    , 1582 (Fed. Cir. 1993) (emphasis
    added). Rather, such possibilities are “contingent and un-
    certain,” “speculative or discretionary,” which is not
    enough. Bowers v. Whitman, 
    671 F.3d 905
    , 913 (9th Cir.
    2012) (citation and internal quotation marks omitted); see
    also 
    id.
     (“To determine whether a property interest has
    vested for Takings Clause purposes, ‘the relevant inquiry
    is the certainty of one’s expectation in the property interest
    at issue.’ . . . [I]f the property interest is ‘contingent and
    uncertain’ or the receipt of the interest is ‘speculative’ or
    ‘discretionary,’ then the government’s modification or re-
    moval of the interest will not constitute a constitutional
    taking.” (citations omitted)); Angelotti Chiropractic, Inc. v.
    Baker, 
    791 F.3d 1075
    , 1081 (9th Cir. 2015) (same).
    At least in the absence of other circumstances not pre-
    sent here, we conclude, the preexisting law limiting title
    means that plaintiffs had no property interest in continued
    possession or transferability that was taken when the Fi-
    nal Rule—validly, by assumption here—required destruc-
    tion or surrender of their bump-stock-type devices.
    2
    Only one more circumstance requires discussion, but it
    does not support a different conclusion. As the Final Rule
    describes, between 2008 and 2017, ATF issued “ten letter
    rulings” stating that certain bump-stock-type devices, in-
    cluding the ones at issue here, did not meet the statutory
    definition of “machinegun” and so were not within the pro-
    hibition of 
    18 U.S.C. § 922
    (o). 83 Fed. Reg. at 66,517–18.
    But those rulings at best gave plaintiffs a property interest
    subject to the express reservation to change the devices’
    Case: 20-1188    Document: 44      Page: 23     Filed: 10/01/2021
    MCCUTCHEN   v. UNITED STATES                                23
    classification if the agency later determined, as it did, that
    the earlier classification was erroneous. Accordingly, those
    letter rulings gave plaintiffs no property right in continued
    possession or transferability.
    ATF’s handbook, which is public, states that a classifi-
    cation provided by letter is “subject to change if later deter-
    mined to be erroneous” by ATF:
    7.2.4 Do you know how ATF would classify
    your product? There is no requirement in the law
    or regulations for a manufacturer to seek an ATF
    classification of its product prior to manufacture.
    Nevertheless, a firearms manufacturer is well ad-
    vised to seek an ATF classification before going to
    the trouble and expense of producing it. Perhaps
    the manufacturer intends to produce a GCA fire-
    arm but not an NFA firearm. Submitting a proto-
    type of the item to ATF’s Firearms Technology
    Branch (FTB) for classification in advance of man-
    ufacture is a good business practice to avoid an un-
    intended classification and violations of the law.
    7.2.4.1 ATF classification letters. ATF
    letter rulings classifying firearms may gen-
    erally be relied upon by their recipients as
    the agency’s official position concerning the
    status of the firearms under Federal fire-
    arms laws. Nevertheless, classifications
    are subject to change if later determined to
    be erroneous or impacted by subsequent
    changes in the law or regulations. To make
    sure their classifications are current,
    FFLs/SOTs [federal firearms licensees/spe-
    cial occupational taxpayers] should stay in-
    formed by periodically checking the
    information published on ATF’s website,
    particularly amendments to the law or

    regulations, published ATF rulings, and
    “open letters” to industry members.
    Handbook § 7.2.4 (italics emphasis added); see also id.
    §§ 1.2.6, 1.2.11 (definitions for “FFL” and “SOT”). The
    quoted express reservation is present in the 2007 Hand-
    book, predating the 2008–17 classification letters at issue,
    and remains there today. Id. § 7.2.4.1. Moreover, it was
    long ago established that, even for formal approvals of im-
    port applications, ATF “must necessarily retain the power
    to correct [an] erroneous approval,” consistent with the
    widespread recognition of “an implied authority in other
    agencies to reconsider and rectify errors even though the
    applicable statute and regulations do not expressly provide
    for such reconsideration.” Gun S., Inc. v. Brady, 
    877 F.2d 858
    , 862–63 (11th Cir. 1989). And the Eleventh Circuit, in
    early February 2009, confirmed specifically with respect to
    a classification ruling involving an early bump-stock-type
    device (the Akins Accelerator) that ATF “had authority to
    ‘reconsider and rectify’ what it considered to be a classifi-
    cation error.” Akins, 312 F. App’x at 200 (quoting Gun S.,
    
    877 F.2d at
    862–63).
    Given the clear provisional character of a classification
    letter, plaintiffs cannot be said to have a compensable prop-
    erty right in the classification letters sent between 2008
    and 2017, which have been properly corrected (as the as-
    sumption of the Final Rule’s validity entails). The Su-
    preme Court in Dames & Moore concluded that the
    President’s nullification of an attachment against certain
    bank assets was not a taking because the pre-attachment
    regulations made clear that, in the Court’s words, “any at-
    tachment is null and void ‘unless licensed,’ and all licenses
    may be revoked at any time.” 
    453 U.S. at
    674 n.6; see also
    
    id. at 663
     (quoting regulations). On that basis, the Court
    held, the “petitioner did not acquire any ‘property’ interest
    in its attachments of the sort that would support a consti-
    tutional claim for compensation.” 
    Id.
     at 674 n.6. We drew
    a similar conclusion in American Bankers Ass’n. We held
    Case: 20-1188    Document: 44      Page: 25    Filed: 10/01/2021
    MCCUTCHEN   v. UNITED STATES                               25
    that the plaintiffs lacked a property right, for takings pur-
    poses, in continuation of a particular statutory dividend
    rate on Federal Reserve stock, where Congress had “ex-
    pressly reserved” its right to change the dividend rate. 932
    F.3d at 1385; cf. Bowen v. Pub. Agencies Opposed to Soc.
    Sec. Entrapment, 
    477 U.S. 41
    , 55 (1986) (“The provision
    simply cannot be viewed as conferring any sort of ‘vested
    right’ in the face of precedent concerning the effect of Con-
    gress’ reserved power on agreements entered into under a
    statute containing the language of reservation.”); Colum-
    bus Reg’l Hosp., 990 F.3d at 1349 (concluding that the
    plaintiff “never had an unconditional interest” in certain
    funds because the government “expressly reserved the
    right to recover those funds for certain reasons within a
    specific period of time”). For the same reason, plaintiffs
    here had no property right in the 2008–17 classification let-
    ters, which the agency could correct for error without ef-
    fecting a taking.
    Although we think that no more is needed to reject
    plaintiffs’ reliance on the 2008–17 letters, we note in addi-
    tion several aspects of those letters, identified by the Final
    Rule itself, that undermine reliance on them as having le-
    gal force and effect. They were informal rulings, not pub-
    lished on ATF’s website or otherwise and not issued
    through the authorized rulemaking process that is pre-
    sumed to be the means of securing Chevron deference. See
    Encino Motorcars, LLC v. Navarro, 
    136 S. Ct. 2117
    , 2125
    (2016) (“A premise of Chevron is that when Congress
    grants an agency the authority to administer a statute by
    issuing regulations with the force of law, it presumes the
    agency will use that authority to resolve ambiguities in the
    statutory scheme.”); United States v. Mead Corp., 
    533 U.S. 218
    , 230 (2001) (“[T]he overwhelming number of our cases
    applying Chevron deference have reviewed the fruits of no-
    tice-and-comment rulemaking or formal adjudication.”).
    ATF’s Handbook, besides expressly declaring the revisabil-
    ity of a classification letter, defines “ATF Ruling” to
    Case: 20-1188     Document: 44       Page: 26    Filed: 10/01/2021
    26                                 MCCUTCHEN   v. UNITED STATES
    “mean[] a formal ruling published by ATF stating its inter-
    pretation of the law and regulations as applied to a specific
    set of facts,” Handbook § 1.2.3 (emphasis added), and says,
    even as to those Rulings, that they “do not have the force
    and effect of law but may be cited as precedent with respect
    to substantially similar fact situations,” id. § 1.4.2. All the
    more so for the informal classification letters. Further, the
    Final Rule suggests that those classification letters were
    “procedurally defective” in a sense recognized in Encino as
    eliminating Chevron deference—namely, they omitted dis-
    cussion that would be needed to meet the requirement of
    “adequate reasons.” 136 S. Ct. at 2125; see Final Rule, 83
    Fed. Reg. at 66,518 (“Of the rulings issued between 2008
    and 2017, ATF provided different explanations for why cer-
    tain bump-stock-type devices were not machineguns, but
    none of them extensively examined the meaning of ‘auto-
    matically.’”).
    Plaintiffs point to the D.C. Circuit’s conclusion that the
    Final Rule is a “legislative rule.” See Guedes v. Bureau of
    Alcohol, Tobacco, Firearms & Explosives, 
    920 F.3d 1
    , 17–
    20 (D.C. Cir. 2019). But that ruling does not aid plaintiffs
    in their takings claim. It does not adjudicate the essential
    question here—whether plaintiffs had a compensable prop-
    erty right in continued possession and transferability
    when, as assumed here, the Final Rule adopted a valid in-
    terpretation of the preexisting ban on possession and
    transfer of “machineguns,” as defined.

    WALLACH, Circuit Judge, concurring in the result.
    I agree we should affirm the Court of Federal Claims’
    decision. I do not, however, agree with the majority’s rea-
    soning and concur as to the result only. I believe the “in-
    here in title” exception, set forth in Lucas, is not the proper
    vehicle to ascertain whether Mr. McCutchen and Paducah
    failed to state a compensable takings claim. That exception
    may inadvertently grant protections reserved to real prop-
    erty, and limited instances of personal property under ex-
    traordinary circumstances, to dangerous and unusual
    weapons. I write separately to explain why the Court of
    Federal Claims correctly concluded that the Bump Stock
    Case: 20-1188    Document: 44      Page: 28    Filed: 10/01/2021
    2                               MCCUTCHEN    v. UNITED STATES
    Rule was not a compensable taking under the police powers
    doctrine.
    I. PROCEDURAL HISTORY
    In December 2018, Mr. McCutchen and Paducah filed
    their Complaint in the Court of Federal Claims. J.A. 22;
    see J.A. 22–30 (Complaint). Paducah is a registered fire-
    arms dealer and retailer of “firearm parts and accessories.”
    J.A. 24. Prior to the Bump Stock Rule, it “had a property
    interest in multiple bump-stock devices.”          J.A. 24.
    Mr. McCutchen previously purchased multiple bump
    stocks “for both his personal use and for economic gain.”
    J.A. 23. The Complaint alleged that the Bump Stock Rule
    constitutes a compensable Fifth Amendment taking of
    bump stocks as it “destroyed all economic value and all in-
    vestment-backed expectations in [parties’] bump-stocks.”
    J.A. 29. The Government moved to dismiss Paducah’s
    Amended Complaint for failure to state a claim on which
    relief can be granted. J.A. 31, 37 (Motion to Dismiss).
    The Court of Federal Claims dismissed Appellants’
    Amended Complaint. See McCutchen v. United States, 
    145 Fed. Cl. 42
    , 45 (2019). The Court of Federal Claims con-
    cluded that Appellants had “failed to state a takings claim,”
    because its “bump-stock devices were not taken for a public
    use, but were instead prohibited through the government’s
    exercise of its police power” and, further, “[e]ven if the po-
    lice power doctrine were inapplicable,” it “would nonethe-
    less dismiss the complaint because there [wa]s no merit to
    [Appellants’] argument that the [Bump Stock] [R]ule ef-
    fected a categorical taking of [its] bump-stock devices.” 
    Id. at 53
    . The Court of Federal Claims concluded that Appel-
    lants suffered neither a physical taking, 
    id.
     at 53–55, nor a
    regulatory taking of their bump stocks, 
    id.
     at 55–56 (noting
    that Appellants had failed to raise any regulatory taking
    arguments and that, “even if the argument were not
    waived, [Appellants] ha[d] failed to state a regulatory tak-
    ings claim”).

    MCCUTCHEN   v. UNITED STATES                              3
    There is no dispute that the Court of Federal Claims
    correctly concluded that Mr. McCutchen and Paducah
    failed to state a compensable takings claim. However, as I
    explain below, I do not agree with the majority’s reasoning
    that the Lucas “inhere in title” exception should extend to
    dangerous and unusual weapons. See Maj. Op. at 4, 16–17.
    In my view, the police power doctrine supports affirming
    the decision of the Court of Federal Claims. For the rea-
    sons which follow, I agree with the Court of Federal Claims
    that the Bump Stock Rule was “an exercise of police power
    and did not effect a taking for public use.” McCutchen, 145
    Fed. Cl. at 51 (capitalization normalized).
    II. THE “INHERE IN TITLE” EXCEPTION IS NOT THE PROPER
    VEHICLE TO ASCERTAIN WHETHER MR. MCCUTCHEN AND
    PADUCAH FAILED TO STATE A COMPENSABLE TAKINGS
    CLAIM
    Lucas holds that a “categorical” takings analysis is ap-
    propriate “where regulation denies all economically benefi-
    cial or productive use of land.” Lucas v. S.C. Coastal
    Council, 
    505 U.S. 1003
    , 1015 (1992); see 
    id.
     at 1015–16 (“As
    we have said on numerous occasions, the Fifth Amendment
    is violated when land-use regulation . . . denies an owner
    economically viable use of his land.” (emphasis in original)
    (internal quotation marks and citation omitted)). The
    cases in which the Supreme Court has applied Lucas’s total
    takings rule have involved real property, and Circuit
    Courts have not reached a clear consensus on how broadly
    to apply Lucas’s per se rule. See Murr v. Wisconsin, 
    137 S. Ct. 1933
    , 1943 (2017) (“By declaring that the denial of all
    economically beneficial use of land constitutes a regulatory
    taking, Lucas stated what it called a ‘categorical’ rule.”);
    Tahoe-Sierra Pres. Council, Inc. v. Tahoe Reg’l Plan.
    Agency, 
    535 U.S. 302
    , 330 (2002) (“[O]ur holding [in Lucas]
    was limited to ‘the extraordinary circumstance when no
    productive or economically beneficial use of land is permit-
    ted.’” (emphasis in original) (quoting Lucas, 
    505 U.S. at 1017
    )); A & D Auto Sales, Inc. v. United States, 748 F.3d
    Case: 20-1188    Document: 44      Page: 30     Filed: 10/01/2021

    1142, 1151–52 (Fed. Cir. 2014) (noting the question and
    collecting cases).
    However, Lucas understands its categorical rule to be
    an application of the Supreme Court’s prior land-use regu-
    lation cases, see Lucas, 
    505 U.S. at
    1015 (citing Agins v.
    City of Tiburon,

    common law.” A & D Auto Sales, 748 F.3d at 1152 (citing
    Lucas,

    As such, Lucas itself expressly declines to extend its
    reasoning to the regulation of personal property. Lucas,
    
    505 U.S. at 1028
    ; see Horne v. Dep’t of Agric., 
    576 U.S. 350
    ,
    361–62 (2015) (clarifying that Lucas’s per se regulatory
    taking analysis applies to real property). Lucas contrasts
    real property, which it concludes is subject to its per se reg-
    ulatory taking rule, with “personal property,” which is not
    subject to the same per se rule. Lucas, 
    505 U.S. at 1028
    ;
    see Horne, 576 U.S. at 361–62. The contrast makes sense,
    as real property is afforded greater protections than per-
    sonal property. See Lucas, 
    505 U.S. at
    1027–28 (“[H]e

    might . . . render his property economically worthless” “by

    Bearing in mind that Lucas warns that personal prop-
    erty owners “ought to be aware of the possibility that new
    regulation might . . . render [their] property economically
    worthless” “by reason of the [government’s] traditionally
    high degree of control over commercial dealings,” Lucas,
    
    505 U.S. at
    1027–28, this court has “applied the categorical
    test to personal property [only] on occasion,” A & D Auto
    Sales, 748 F.3d at 1151. Accordingly, this court has cau-
    tiously examined the “inhere title” exception in cases in-
    volving non-physical personal property, specifically, liens,
    permits, or higher statutory dividend rates. See American
    Bankers Ass’n v. United States, 
    932 F.3d 1375
    , 1384–86
    (Fed. Cir. 2019) (concluding that plaintiffs had no property
    interest in a higher statutory dividend rate on Federal Re-
    serve stock); A & D Auto Sales, 748 F.3d at 1151–52 (de-
    clining to decide the issue of whether Lucas should extend
    to “intangible [personal] property”); Bair v. United States,
    
    515 F.3d 1323
    , 1327 (Fed. Cir. 2008) (concluding that the
    “inhere in title” exception did apply to federal statutory
    processor liens); Conti v. United States, 
    291 F.3d 1334
    ,
    1343 (Fed. Cir. 2002)(concluding that a swordfishing per-
    mit did not constitute a cognizable property interest).
    I fear that the majority has overread our case law by
    extending Lucas’s per se regulatory taking analysis to dan-
    gerous and unusual weapons; here, bump stocks. The ma-
    jority cites cases that appear inapplicable here; those cases
    address non-physical personal property—not physical per-
    sonal property, like bump stocks. See Maj. Op. at 15–18

    (discussing whether plaintiff had property interest in stat-
    utory processor liens)). Additionally, the majority does not
    cite a single case where a court concluded that a claimant
    did not have a cognizable property interest in physical
    property. See Maj. Op. at 15–18. Such an overextension of
    our case law may inadvertently afford dangerous and unu-
    sual weapons special protections that are reserved to real
    property and limited instances of personal property, as dis-
    cussed in Lucas. Consequently, in my opinion, the “inhere
    in title” exception is an inappropriate vehicle to ascertain
    whether Mr. McCutchen and Paducah failed to state a com-
    pensable takings claim. Instead, for the reasons to follow,
    I would affirm under the police powers doctrine.
    III. MR. MCCUTCHEN AND PADUCAH’S TAKINGS CLAIMS ARE
    PRECLUDED BY THE POLICE POWERS DOCTRINE
    The Court of Federal Claims concluded that the Bump
    Stock Rule “did not effect a taking for public use” under the
    police powers doctrine. McCutchen, 145 Fed. Cl. at 51 (cap-
    italization normalized). The Court of Federal Claims ex-
    plained that “it is well established that there is no
    [compensable] taking for ‘public use’ where,” as here, “the
    government acts pursuant to its police power” to “criminal-
    ize[] or otherwise outlaw[] the use or possession of property
    that presents a danger to the public health and safety.” Id.

    States, 
    525 F.3d 1149
    , 1153 (Fed. Cir. 2008)).
    Mr. McCutchen and Paducah argue that the Court of Fed-
    eral Claims “erred” when it “determin[ed] that [their] prop-
    erty was not taken ‘for public use’” under the police powers
    doctrine. Appellants’ Br. 9. I disagree with Appellants.
    “Long ago” the Supreme Court “recognized that ‘all
    property in this country is held under the implied obliga-
    tion that the owner’s use of it shall not be injurious to the

    community’” and that “the Takings Clause did not trans-
    form that principle to one that requires compensation
    whenever the [government] asserts its power to enforce”
    that implied obligation. Keystone Bituminous, 
    480 U.S. at
    491–92 (quoting Mugler, 
    123 U.S. at 665
    ). Accordingly, cer-
    tain government actions in furtherance of the health,
    safety, and general welfare of the public have a “special
    status” within our takings jurisprudence. 
    Id.

    see 
    id.
     at 491 n.20 (explaining that “since no individual has
    a right to use his property so as to create a nuisance or oth-
    erwise harm others, the [government] has not ‘taken’ any-
    thing when it asserts its power to enjoin the nuisance-like
    activity”); see also Ruckelshaus, 
    467 U.S. at 1005
     (conclud-
    ing that a health and safety regulation’s lack of “interfer-
    ence with reasonable investment-backed expectations” was
    “so overwhelming . . . that it disposes of the taking ques-
    tion” (internal quotation marks and citation omitted)).
    Courts have sometimes described such actions as a “legiti-
    mate exercise of the government’s police power,” rather
    than a compensable taking, Murr, 137 S. Ct. at 1947, or as
    non-compensable under the “police power doctrine,” Akins

    1   This nomenclature has its roots in the Supreme
    Court’s early police power cases, prior to the advent of its
    regulatory takings jurisprudence, when a regulation pur-
    suant to the government’s “police power” did not effect a
    compensable taking. Murr, 137 S. Ct. at 1942–47; see
    Horne, 576 U.S. at 360 (“Prior to th[e Supreme] Court’s de-
    cision in [Pennsylvania Coal Co. v. Mahon, 
    260 U.S. 393
    (1922)], the Takings Clause was understood to provide pro-
    tection only against a direct appropriation of property—
    personal or real.”). In Pennsylvania Coal, the Supreme
    Court held that “[t]he general rule” is that “if regulation
    goes too far it will be recognized as a taking.” 260 U.S. at

    compensation when it diminishes or destroys the value of
    property by stopping illegal activity or abating a public nui-
    sance.” Keystone Bituminous,

    polo Fuels, Inc. v. United States, 
    381 F.3d 1338
    , 1347 (Fed.
    Cir. 2004). Similarly, “[w]hen property has been seized
    pursuant to the criminal laws or subjected to in rem forfei-
    ture proceedings, such deprivations are not [compensable]
    takings.” Acadia Tech., Inc. v. United States, 
    458 F.3d 1327
    , 1331 (Fed. Cir. 2006) (internal quotation marks omit-

    The Court of Federal Claims correctly concluded that
    the Bump Stock Rule was not a compensable taking under
    the police powers doctrine. Congress enacted the National
    Firearms Act (“NFA”) and Gun Control Act (“GCA”) to reg-
    ulate “lethal weapons,” particularly machine guns, “[that]
    could be used readily and efficiently by criminals.” H.R.

    Bump Stock Rule clarified that bump stocks fall within the
    statutory term “machinegun,” because they “convert an
    otherwise semiautomatic firearm into a machinegun,” and
    therefore, also fall within the criminal prohibition on the
    transfer and possession of machine guns. Bump Stock

    . Mr. McCutchen and
    Paducah, therefore, lack a compensable takings claim for
    their bump stocks against the Bump Stock Rule, because it
    is precluded by the police powers doctrine. Accordingly, the
    Bump Stock Rule’s requirement that possessors destroy or
    relinquish their bump stocks as illegal machine guns is not
    a taking of “private property . . . for public use, without just
    compensation.” U.S. CONST. amend. V, cl. 4.
    Mr. McCutchen and Paducah’s counterarguments are
    unpersuasive. First, Appellants argue that the “‘police
    powers’ exception” is inapplicable here because the doc-
    trine only applies when the “government acts in its enforce-
    ment capacity, e.g., when it enforces an existing criminal or

    (citing Gibson Wine Co. v. Snyder, 
    194 F.2d 329
    , 331 (D.C.
    Cir. 1952))). This argument is without merit.
    Appellants ignore that the Bump Stock Rule was prom-
    ulgated to enforce an existing criminal law—the prohibi-
    tion on transfer and possession of machine guns, including
    parts designed to convert weapons into a machine gun,
    manufactured after 1986.

    must regulate them as such” and “does not have the au-
    thority to restrict only the future manufacture and sale of
    bump-stock-type devices” or “remove the general prohibi-
    tion on the transfer and possession of machineguns that
    were not lawfully possessed” prior to 1986). Appellants
    also fail to recognize that the ATF acted within an estab-
    lished regulatory regime, pursuant to delegated and re-
    tained discretion, to conclude that Appellants’ bump stocks
    “allow a shooter of a semiautomatic firearm to initiate a
    continuous firing cycle with a single pull of the trigger” and
    to classify Appellants’ bump stocks as illegal machine guns.
    Bump Stock Rule, 83 Fed. Reg. at 66,515–16; see id.
    at 66,520 (“The reason for the [ATF’s] classification change
    is that ATF, upon review . . . believes that bump-stock-type

    fied bump stocks as illegal machine guns, the ATF acted in
    its enforcement capacity when it required Appellants aban-
    don or destroy their bump stocks—specifically, to enforce
    the criminal prohibition on the possession of illegal ma-
    chine guns. Bump Stock Rule, 83 Fed. Reg. at 66,530

    Bump Stock Rule requires “possessors of bump-stock-type

    that failure to comply by the “effective date” will result in
    “violation of Federal law”), 66,544 (explaining that “this

    hibit machineguns”); see

    Appellants’ Br. 15 (agreeing that “[t]he government is not
    required to pay compensation for a taking when a property
    owner is deprived of his property rights as a consequence
    of a government enforcement action.” (citing Bennis, 
    516 U.S. at 442
    )).
    Second, Mr. McCutchen and Paducah assert that the
    Court of Federal Claims erred because “[t]he Supreme
    Court’s early ‘police powers’ cases do not defeat the public
    use prong of [their] claims.” Appellants’ Br. 11 (citing Mil-
    ler, 
    276 U.S. 272
    ; Mugler, 
    123 U.S. 623
    ). They argue that
    “the ‘harmful or noxious use’ principle,” articulated in the
    “Miller and Mugler cases was nothing more than the Su-
    preme Court’s early formulation of the police power justi-
    fying a regulatory diminution in value of property without
    compensation,” 
    id.
     (citing Lucas, 
    505 U.S. at 1004
    ), and
    therefore inapplicable to the “total[] depriv[ation] of their
    property” effected by the Bump Stock Rule, id. at 14. This
    argument is without merit.
    As an initial matter, the police power doctrine is not
    directed to the “public use” prong of our takings analysis.
    The police power doctrine is directed to the question of
    whether property has been “taken.” Keystone Bituminous,
    
    480 U.S. at
    491 n.20. If property has not been taken, then
    compensation is not required. See Lingle, 
    544 U.S. at
    536–
    37. The public use prong is directed to whether property,
    having been taken, was taken for a “public use.” See 
    id. at 543
    . If property has not been taken for “public use,” then
    “[n]o amount of compensation can authorize [the] action.”
    Id.; see Hawaii Hous. Auth. v. Midkiff, 
    467 U.S. 229
    , 239
    (1984). The police power doctrine is premised “on the sim-
    ple theory that since no individual has a right to use his
    property so as to create a nuisance or otherwise harm oth-
    ers, the [s]tate has not ‘taken’ anything when it asserts its
    power to enjoin the nuisance-like activity.” Keystone Bitu-
    minous, 
    480 U.S. at
    491 n.20; see Bennis, 
    516 U.S. at 453
    ;
    Acadia, 
    458 F.3d at 1331
    . It focuses on specific exercises of
    the police power in furtherance of the health, safety, and

    general welfare of the public. Keystone Bituminous, 
    480 U.S. at
    491–92; see Berman v. Parker, 
    348 U.S. 26
    , 32
    (1954) (explaining that “[p]ublic safety” and “public health”
    are “some of the more conspicuous examples of the tradi-
    tional application of the police power,” and therefore “they
    merely illustrate the scope of the power and do not delimit
    it”). In contrast, the public use prong seeks to prevent the
    government from taking property “for the purpose of con-
    ferring a private benefit on a particular private party.”
    Kelo v. City of New London, Conn., 
    545 U.S. 469
    , 477
    (2005). It focuses broadly on whether a taking is for “public
    purpose,” 
    id. at 480
    , and, therefore, unlike the police pow-
    ers doctrine, is “coterminous” with the full “scope of a sov-
    ereign’s police powers,” Midkiff, 
    467 U.S. at 240
    ; see 
    id. at 239
     (“An attempt to define [the police powers’] reach or
    trace its outer limits is fruitless, for each case must turn on
    its own facts.” (quoting Berman, 
    348 U.S. at 32
    )); Kelo, 
    545 U.S. at 483
     (“[Supreme Court] public use jurisprudence has
    wisely eschewed rigid formulas and intrusive scrutiny in
    favor of affording legislatures broad latitude in determin-
    ing what public needs justify the use of the takings
    power.”).
    More substantively, Appellants misunderstand the im-
    port of the Supreme Court’s early police power cases to our
    analysis here. We do not need to analogize solely from
    cases about the state-mandated closure of breweries, see
    Mugler, 
    123 U.S. at 623
    , and compelled destruction of dis-
    eased cedar trees, see Miller, 
    276 U.S. at
    279–80, to con-
    clude that the government may ban dangerous and
    unusual weapons, see Heller, 
    554 U.S. at 627
    , and enforce
    that ban without compensation, see Bennis, 
    516 U.S. at
    452–53; Calero-Toledo, 
    416 U.S. at 683
    ; Acadia, 
    458 F.3d at
    1331–32. Rather, because the Supreme Court’s takings
    jurisprudence has “traditionally been guided” by the rea-
    sonable expectations of property owners, we may look to
    these early cases to establish that, “[a]s long recognized,
    some values are enjoyed under an implied limitation and
    Case: 20-1188    Document: 44      Page: 42    Filed: 10/01/2021

    must yield to the police power.” Lucas, 
    505 U.S. at 1027
    (quoting Pennsylvania Coal, 
    260 U.S. at 413
    ); see, e.g., Key-
    stone Bituminous, 
    480 U.S. at 490
     (explaining that in Mil-
    ler, 
    276 U.S. 272
    , the Supreme Court concluded that “the
    Takings Clause did not require the [state] to compensate
    the owners of cedar trees for the value of the trees that the
    [s]tate had ordered destroyed,” because “it was clear that
    the [s]tate’s exercise of its police power to prevent the im-
    pending danger was justified, and did not require compen-
    sation”), 491–92 (quoting Mugler, 
    123 U.S. at 665
    , for the
    proposition that “[l]ong ago it was recognized that ‘all prop-
    erty in this country is held under the implied obligation
    that the owner’s use of it shall not be injurious to the com-
    munity’”); Allied-Gen. Nuclear Servs. v. United States, 
    839 F.2d 1572
    , 1576 (Fed. Cir. 1988) (noting that in Keystone
    Bituminous “the Supreme Court has dusted off Mugler and
    put it back on its pedestal”).
    Further, contrary to Appellants’ arguments, the Su-
    preme Court’s early police-power cases are not limited to
    the “diminution of rights” through “government regulation
    of use,” Appellants’ Br. 14, but instead confirm the govern-
    ment’s longstanding authority to regulate personal prop-
    erty, even to “the destruction of [that] property,” without a
    categorical duty to compensate. Samuels v. McCurdy, 
    267 U.S. 188
    , 196 (1925). For example, in Samuels, the Su-
    preme Court concluded that the seizure of “certain intoxi-
    cating liquors” pursuant to a state’s criminal prohibition,
    even to “the destruction of property” and disappointment
    of a previously legal interest, was not a compensable taking
    because the case did “not involve the power of eminent do-
    main,” but the “police power.” 
    Id. at 190
    , 195–96. Simi-
    larly, in Omnia Com. Co. v. United States, the Supreme
    Court concluded that Federal requisition of a “steel com-
    pany’s entire production of steel plate for the year 1918”
    was not a compensable taking of another company’s preex-
    isting contract to buy that steel, as the “destruction of, or
    injury to, property is frequently accomplished without a
    Case: 20-1188    Document: 44      Page: 43     Filed: 10/01/2021
    MCCUTCHEN   v. UNITED STATES                                17
    ‘taking’ in the constitutional sense.” 
    261 U.S. 502
    , 507–08
    (1923). Thus, the early police power cases support the con-
    clusion that “not every destruction or injury to property by
    governmental action” is a “‘taking’ in the constitutional
    sense,” Armstrong v. United States, 
    364 U.S. 40
    , 48 (1960),
    but rather may be a non-compensable exercise of the police
    power, Lucas, 
    505 U.S. at 1027
     (explaining that “some val-
    ues . . . must yield to the police power” (quoting Pennsylva-
    nia Coal, 
    260 U.S. at 413
    )); Chicago, B. & Q. Ry. Co. v.
    Illinois, 
    200 U.S. 561
    , 594 (1906) (explaining that the Tak-
    ings Clause “is not intended as a limitation of the exercise
    of those police powers which are necessary to the tranquil-
    ity of every well-ordered community” as “[i]t has always
    been held that the legislature may make police regulations,
    although they may interfere with the full enjoyment of pri-
    vate property, and though no compensation is given” (cita-
    tion omitted)); see, e.g., Juragua Iron Co. v. United States,
    
    212 U.S. 297
    , 305 (1909) (concluding that Takings “princi-
    ple[s]” could not “be enforced in respect of [real and per-
    sonal] property destroyed by the United States in the
    course of military operations for the purpose . . . of protect-
    ing the health and lives of its soldiers,” specifically, in the
    belief that it would prevent the spread of infectious dis-
    ease); Bowditch v. City of Bos., 
    101 U.S. 16
    , 18–19 (1879)
    (finding no compensable taking for the destruction of prop-
    erty to prevent the spread of fire, explaining that “[a]t the
    common law every one had the right to destroy real and
    personal property, in cases of actual necessity, to prevent
    the spreading of a fire” with “the common law adopt[ing]
    the principle of the natural law, and find[ing] the right and
    the justification in the same imperative necessity”). Ac-
    cordingly, the Court of Federal Claims correctly concluded
    that the Bump Stock Rule was not a compensable taking
    under the police powers doctrine.
    IV. CONCLUSION
    I would affirm the decision of the Court of Federal
    Claims that, “[Mr. McCuthcen and Paducah’s] bump-stock
    Case: 20-1188   Document: 44    Page: 44    Filed: 10/01/2021

    devices were not taken for a public use, but were instead
    prohibited through the government’s exercise of its police
    power.” McCutchen, 145 Fed. Cl. at 53. I therefore concur
    in today’s result.
