    JUSTIN J. SADLER,                                        (D. Wyo.)
    Defendant-Appellant.
    ORDER AND JUDGMENT *
    Before HARTZ, HOLMES, and PHILLIPS, Circuit Judges.
    After he was convicted of being a felon in possession of a firearm in
    violation of 18 U.S.C. §§ 922(g)(1) and 924(a)(2), Defendant-Appellant Justin
    Sadler was sentenced to a term of 120 months’ imprisonment. He contends that
    his sentencing range—determined pursuant to the United States Sentencing
    Guidelines (“U.S.S.G.” or “Guidelines”)—is both procedurally and substantively
    *
    Having examined the briefs and appellate record, this panel has
    decided unanimously to grant the parties’ request for a decision on the briefs
    without oral argument. See Fed. R. App. P. 34(f); 10th Cir. R. 34.1(G). The case
    is therefore ordered submitted without oral argument.
    This order and judgment is not binding precedent, except under the
    doctrines of law of the case, res judicata, and collateral estoppel. It may be cited,
    however, for its persuasive value consistent with Federal Rule of Appellate
    Procedure 32.1 and Tenth Circuit Rule 32.1.
    unreasonable. Exercising jurisdiction under 18 U.S.C. § 3742(a) and 28
    U.S.C. § 1291, we reject these challenges and affirm the judgment of the district
    court.
    I
    The events giving rise to the prosecution in this case transpired during the
    late hours of February 1, 2013, and the early hours of February 2, 2013. That
    night, Alicia Klein began receiving text messages from Mr. Sadler—her former
    boyfriend—who wanted her to “hang out with him” and threatened to “come there
    and beat . . . up” her social companions when she declined. R., Vol. 4, at 76
    (Trial Tr., dated Dec. 9, 2013). Later in the evening, Mr. Sadler sent more text
    messages asking Ms. Klein to pick him up from his boss’s home because he was
    too inebriated to drive. Ms. Klein agreed.
    When Ms. Klein arrived at the pre-arranged location, she found Mr. Sadler
    getting into a physical altercation with his father, Craig Sadler (“Craig”). Once
    the men stopped fighting, Ms. Klein, following Craig, drove Mr. Sadler to Craig’s
    residence. Mr. Sadler “wanted to fight and argue” with Ms. Klein during the car
    ride; she asked him to be quiet. 
    Id. at 79.
    After reaching Craig’s home, Ms. Klein went inside to assist Craig with his
    blood-pressure medication and then agreed to stay and talk to Mr. Sadler. She
    and Mr. Sadler went into Mr. Sadler’s bedroom, but she decided to leave once it
    became obvious that Mr. Sadler “wanted to talk about [her] being with one of
    2
    [her] ex-boyfriends, [which] always led to a fight.” 
    Id. at 80.
    Her attempted
    departure prompted Mr. Sadler to throw her “across the bed into the wall.” 
    Id. Ms. Klein
    then endeavored to get up, collect her car keys and phone from the
    kitchen, and leave. At that point, Mr. Sadler ran to the kitchen and opened a
    door. He threw Ms. Klein’s keys and phone out of the door and “threw [Ms.
    Klein] outside down the stairs,” ripping her shirt in the process. 
    Id. Finding herself
    locked outside the residence, shoeless and shirtless in
    extremely cold weather, Ms. Klein pounded on the door and begged to be let
    inside. Eventually either Mr. Sadler or Craig unlocked the door, and she went
    back into the home and saw Mr. Sadler standing near a handgun that was on a
    television stand. She had not noticed a gun in the house before Mr. Sadler threw
    her outside—or, for that matter, during any prior visit to that residence.
    Shortly after Ms. Klein re-entered the home, Mr. Sadler picked up the gun
    and said, “[T]his is a hostage situation and nobody is going anywhere.” 
    Id. at 82.
    He then repeatedly tapped the gun against the back of Ms. Klein’s head and her
    temple. Ms. Klein tried to defend herself by hitting Mr. Sadler in the face three
    times, which only served to make him angrier. Concerned that “somebody [had]
    called the cops,” Mr. Sadler began “pacing back and forth” with the gun. 
    Id. at 83.
    Eventually, Ms. Klein coaxed Mr. Sadler to lie down in his bedroom with
    her—although he held onto the gun—and they both fell asleep.
    3
    When Ms. Klein awoke the next morning, the gun was “lean[ing] up against
    the window sill” of Mr. Sadler’s bedroom. 
    Id. at 85.
    Craig took possession of the
    gun, and Ms. Klein retrieved her phone. Because Ms. Klein could not find her car
    keys, she waited “about [forty-five] minutes to an hour” for a friend to come and
    pick her up. 
    Id. at 87.
    She told her friend that “something really bad [had]
    happened” when she requested a ride home. 
    Id. Within approximately
    one hour,
    she received a text message from Mr. Sadler that said, “Last night was
    regrettable. I hate it all. I probably should have shot myself.” 
    Id. at 88.
    A federal grand jury of the United States District Court for the District of
    Wyoming returned a one-count indictment against Mr. Sadler on May 23, 2013,
    charging him with being a felon in possession of a firearm in violation of 18
    U.S.C. §§ 922(g)(1) and 924(a)(2). Although he originally agreed to plead guilty
    to the charges, Mr. Sadler exercised his right to a jury trial that took place on
    December 9 and 10, 2013. The jury found him guilty as charged.
    Using the 2012 version of the Guidelines, the United States Probation
    Office prepared a presentence investigation report (“PSR”). The PSR observed
    that Mr. Sadler had a prior felony conviction and determined the appropriate base
    offense level with reference to U.S.S.G. § 2K2.1 (the guideline for felon-in-
    possession offenses). Because it concluded that Mr. Sadler possessed the
    prohibited gun in connection with the commission of another felony
    offense—specifically, “[k]idnapping which resulted in the victim being sexually
    4
    assaulted [1] while the defendant possessed a firearm,” R., Vol. 2, ¶ 53, at 46
    (Revised Presentence Investigation Report, filed Dec. 11, 2013)—the PSR cross-
    referenced U.S.S.G. § 2X1.1 in its computations. See U.S.S.G. § 2K2.1(c)(1)(A).
    That guideline (i.e., § 2X1.1) directed the use of “[t]he base offense level from
    the guideline for the substantive offense, plus any adjustments from such
    guideline for any intended offense conduct that can be established with reasonable
    certainty.” 
    Id. § 2X1.1(a).
    Further reference to the guideline for the substantive
    offense of kidnapping 2 yielded a base offense level of thirty-two. See 
    id. § 2A4.1(a)
    (kidnapping guideline).
    The PSR then recommended a two-level sentencing increase, pursuant to
    U.S.S.G. § 2A4.1(b)(3), based upon its finding that Mr. Sadler possessed a
    “dangerous weapon” that he used to confine Ms. Klein unlawfully in Craig’s
    residence when she attempted to leave. PSR, ¶ 13, at 37. It also prescribed a six-
    level increase, as set forth in U.S.S.G. § 2A4.1(b)(5), because it found that Mr.
    Sadler sexually exploited Ms. Klein “while [he] was preventing her from leaving
    the residence.” PSR, ¶ 14, at 37. Referencing Mr. Sadler’s adjusted offense level
    of 40 and his criminal history category of IV, the PSR computed an advisory
    1
    Although the district court prohibited all of the witnesses at Mr.
    Sadler’s trial from discussing allegations of sexual assault, the court permitted
    testimony of this nature during the sentencing hearing.
    2
    The PSR also indicated that Mr. Sadler had been charged in state
    court with “several counts relating to th[e] federal [i]ndictment,” PSR, ¶ 29, at 41,
    and that one of those charges was kidnapping in violation of Wyoming law.
    5
    Guidelines range of 360 months to life imprisonment. However, it ultimately
    recommended a term of imprisonment of 120 months (i.e., ten years)—the
    statutorily authorized maximum sentence for Mr. Sadler’s offense of conviction. 3
    See U.S.S.G. § 5G1.1(a) (“Where the statutorily authorized maximum sentence is
    less than the minimum of the applicable guideline range, the statutorily
    authorized maximum sentence shall be the guideline sentence.”).
    In a filed response to the PSR, Mr. Sadler disputed the cross-reference to
    the kidnapping guideline to establish his base offense level and objected to the
    imposition of the two above-noted sentencing enhancements. He renewed these
    objections at sentencing. Notably, he insisted that “the facts d[id] not fit the
    cross-referenc[e]” to kidnapping, R., Vol. 4, at 332 (Tr. Sent’g Hr’g, dated Jan. 6,
    2014)—an offense which requires some degree of involuntary detention of
    another individual under the relevant federal and Wyoming statutes. 4 Mr. Sadler
    3
    See 18 U.S.C. § 924(a)(2) (providing that individuals convicted of
    violating 18 U.S.C. § 922(g) “shall be . . . imprisoned not more than 10 years”).
    4
    The federal kidnapping statute prohibits “unlawfully seiz[ing or]
    confin[ing]” another “and hold[ing that person] for . . . reward.” 18 U.S.C.
    § 1201(a). “Our cases have interpreted this statute to require, inter alia, that the
    victim be (1) held against his or her will (2) for some benefit to the captor.”
    United States v. Gabaldon, 
    389 F.3d 1090
    , 1094 (10th Cir. 2004); see United
    States v. Toledo, 
    985 F.2d 1462
    , 1467 (10th Cir. 1993) (“[T]he involuntariness of
    the seizure and detention . . . is the very essence of the crime of kidnapping.”
    (omission in original) (emphasis omitted) (quoting Chatwin v. United States, 
    326 U.S. 455
    , 464 (1946))). Similarly, Wyoming defines kidnapping, in relevant part,
    as the “unlawful[] confine[ment of] another person, with the intent
    to . . . [f]acilitate the commission of a felony; or . . . [i]nflict bodily injury on or
    (continued...)
    6
    claimed that the kidnapping cross-reference lacked an adequate factual basis
    because Ms. Klein eventually left Craig’s home voluntarily and did so without
    reporting the incident to law enforcement. Additionally, he argued that it would
    be “disturbing and unfair” for the court to impose a sentence “based on mostly
    hearsay-type evidence” concerning kidnapping. R., Vol. 4, at 333.
    The evidence to which Mr. Sadler apparently objected on hearsay grounds
    was sentencing-hearing testimony given by Corporal Paul Pownall, an
    investigator with the Campbell County, Wyoming, Sheriff’s Office. Corporal
    Pownall, who had testified at Mr. Sadler’s trial, appeared at the sentencing to
    4
    (...continued)
    to terrorize the victim or another.” Wyo. Stat. Ann. § 6-2-201(a). Such
    “confinement is unlawful if it is accomplished . . . [b]y force.” 
    Id. § 6-2-
    201(b)(i).
    Both statutes patently implicate the conduct the government sought to
    prove concerning Mr. Sadler—viz., that, in the course of illegally possessing a
    firearm, he unlawfully held Ms. Klein against her will for the purpose, at least in
    part, of committing a sexual assault on her (i.e, the illicit benefit). The
    Guidelines make clear that the cross-reference applies when “the defendant used
    or possessed any firearm . . . in connection with the commission . . . of another
    offense,” U.S.S.G. § 2K2.1(c)(1) (emphasis added)—without regard to the
    statutory source of that other offense. For our purposes, therefore, the relevant
    considerations are: (1) that Mr. Sadler was adjudicated guilty of being a felon in
    possession, and (2) that he was sentenced according to a guideline generally
    implicating kidnapping as the underlying substantive offense. We do not purport
    to decide whether Mr. Sadler could actually have been convicted of kidnapping
    beyond a reasonable doubt under federal or Wyoming law because Ҥ 2X1.1,
    when cross-referenced by § 2K2.1(c), does not require a conviction before a
    district court may use the guideline provision applicable to the conduct
    underlying the firearm offense.” United States v. O’Flanagan, 
    339 F.3d 1229
    ,
    1234 (10th Cir. 2003).
    7
    discuss the fruits of his February 25, 2013, interview with Ms. Klein. He stated
    that Ms. Klein had conveyed that “Justin Sadler tried to have sex with her,” and
    that she had indicated that her response was: “Justin, no. I don’t want to have sex
    with you. You disgust me.” R., Vol. 4, at 317. According to Corporal Pownall,
    Ms. Klein then told him the specifics of Mr. Sadler’s rejoinder—“You wouldn’t
    say no to somebody who had a gun”—and admitted that she did have sex with Mr.
    Sadler that night because she “felt coerced into” doing so. 
    Id. at 317–18.
    Mr. Sadler personally made an unsworn statement at the sentencing hearing
    wherein, inter alia, he denied committing the alleged sexual assault and suggested
    that he had been denied the opportunity to confront his accusers “to refute the[ ]
    kidnapping charges.” 
    Id. at 348.
    However, the district court ultimately rejected
    Mr. Sadler’s various objections, accepted the PSR’s findings, and imposed the
    statutorily authorized maximum sentence of 120 months. Mr. Sadler has timely
    appealed.
    II
    Turning to Mr. Sadler’s challenges to the sentence he received, “[w]e
    review sentences for reasonableness under a deferential abuse of discretion
    standard.” United States v. Haley, 
    529 F.3d 1308
    , 1311 (10th Cir. 2008); see
    United States v. Smart, 
    518 F.3d 800
    , 803 (10th Cir. 2008) (noting that “[s]ince
    the Supreme Court’s decision in [United States v. Booker, 
    543 U.S. 220
    (2005)],
    which relegated the Sentencing Guidelines to an advisory status, district courts
    8
    have been free to apply any sentence that is ‘reasonable’ under the sentencing
    factors listed at 18 U.S.C. § 3553(a)”). Our assessment of reasonableness
    “includes both procedural reasonableness, which encompasses the manner in
    which a sentence was calculated, and substantive reasonableness, which concerns
    the length of the sentence.” United States v. Caiba-Antele, 
    705 F.3d 1162
    , 1165
    (10th Cir. 2012); accord United States v. Scott, 
    529 F.3d 1290
    , 1299–1300 (10th
    Cir. 2008).
    On appeal, Mr. Sadler disputes the procedural and substantive
    reasonableness of his 120-month sentence. We address his arguments in turn.
    A
    “A sentence is procedurally unreasonable if the district court incorrectly
    calculates or fails to calculate the Guidelines sentence, treats the Guidelines as
    mandatory, fails to consider the § 3553(a) factors, relies on clearly erroneous
    facts, or inadequately explains the sentence.” 
    Haley, 529 F.3d at 1311
    ; accord
    United States v. Zapata, 
    546 F.3d 1179
    , 1192 (10th Cir. 2008). In our assessment
    of procedural reasonableness, we ask whether the district court “set forth enough
    to satisfy the appellate court that [it] has considered the parties’ arguments and
    has a reasoned basis for exercising [its] own legal decisionmaking authority.”
    United States v. Lente, 
    759 F.3d 1149
    , 1156 (10th Cir. 2014) (alterations in
    original) (quoting Rita v. United States, 
    551 U.S. 338
    , 356 (2007)). Ultimately,
    because a procedural error “amounts to an abuse of discretion . . . , ‘we review a
    9
    district court’s legal interpretation of the Guidelines de novo and its factual
    findings for clear error.’” United States v. Cook, 
    550 F.3d 1292
    , 1295 (10th Cir.
    2008) (citation omitted) (quoting United States v. Smith, 
    534 F.3d 1211
    , 1226
    (10th Cir. 2008)).
    Mr. Sadler contends that the district court committed procedural error when
    it cross-referenced from U.S.S.G. § 2K2.1, the felon-in-possession guideline, to
    U.S.S.G. § 2A4.1, the kidnapping guideline. He advances three strands of
    reasoning to support his view that his sentence is procedurally
    unreasonable—namely, he argues that (1) facts supporting a cross-reference must
    be proven beyond a reasonable doubt; (2) various decisions of the Supreme Court
    demonstrate that the district court erred when it cross-referenced to the
    kidnapping guideline; and (3) the district court committed procedural error by
    violating his Sixth Amendment Confrontation Clause rights during the sentencing
    hearing. For the reasons that follow, we conclude that binding precedent easily
    forecloses each of Mr. Sadler’s theories and underscores the procedural
    reasonableness of his sentence.
    1
    In his first challenge to the procedural reasonableness of his sentence, Mr.
    Sadler avers generally that the cross-referencing mechanism “should not [have]
    be[en] used” unless facts supporting utilization of the kidnapping guideline were
    “proved beyond a reasonable doubt.” Aplt. Opening Br. at 17. However, Mr.
    10
    Sadler’s argument is predicated on a fundamental misunderstanding of the law of
    criminal sentencing. Accordingly, we decline to accept it.
    a
    Section 2K2.1 of the Guidelines, which governs unlawful possession of a
    firearm, directs a sentencing court as follows: “If the defendant used or possessed
    any firearm or ammunition in connection with the commission or attempted
    commission of another offense, . . . apply . . . § 2X1.1 (Attempt, Solicitation, or
    Conspiracy) in respect to that other offense, if the resulting offense level is
    greater than that determined above.” U.S.S.G. § 2K2.1(c)(1)(A). Application
    note 14 to § 2K2.1 defines “another offense,” for purposes of subsection (c)(1), as
    “any federal, state, or local offense, other than the explosive or firearms
    possession or trafficking offense, regardless of whether a criminal charge was
    brought, or a conviction obtained.” 
    Id. § 2K2.1
    cmt. n.14(C). With the foregoing
    in mind, turning to § 2X1.1, a court must utilize “[t]he base offense level from the
    guideline for the substantive offense, plus any adjustments from such guideline
    for any intended offense conduct that can be established with reasonable
    certainty.” 
    Id. § 2X1.1(a).
    This cross-referencing mechanism “permit[s] the sentencing court’s
    consideration of other offense conduct even though [the] defendant was only
    convicted of being a felon in possession of a firearm . . . .” United States v.
    O’Flanagan, 
    339 F.3d 1229
    , 1232 (10th Cir. 2003); see United States v. Willis,
    11
    
    925 F.2d 359
    , 361 (10th Cir. 1991) (“[T]he cross reference to § 2X1.1 requires
    that when a defendant uses an illegal firearm to commit other offense conduct that
    he be sentenced according to such other offense conduct even though his
    conviction is only for the unlawful possession of firearms.”). It preserves the
    sentencing court’s considerable discretion; “‘a perfect match is not required’
    between the defendant’s conduct and the . . . guideline selected as the most
    analogous” in terms of the substantive offense. United States v. Cherry, 
    572 F.3d 829
    , 831 (10th Cir. 2009) (quoting United States v. Fortier, 
    180 F.3d 1217
    , 1229
    (10th Cir. 1999)).
    Critically, as a matter of well-settled law, Ҥ 2X1.1, when cross-referenced
    by § 2K2.1(c), does not require a conviction before a district court may use the
    guideline provision applicable to the conduct underlying the firearm offense.”
    
    O’Flanagan, 339 F.3d at 1234
    (emphasis added); see 
    Willis, 925 F.2d at 360
    ;
    accord United States v. Earls, 
    704 F.3d 466
    , 474 (7th Cir. 2012); United States v.
    Drew, 
    200 F.3d 871
    , 877–79 (D.C. Cir. 2000); United States v. Branch, 
    91 F.3d 699
    , 742–43 (5th Cir. 1996); United States v. Fleming, 
    8 F.3d 1264
    , 1266–67 (8th
    Cir. 1993). Our interpretation and application of this guideline “is confirmed by
    an analysis of the express intent of the Sentencing Commission, the uniformity of
    persuasive authorities, the purpose of the Sentencing Guidelines, and the context
    in which § 2X1.1 is used.” 
    O’Flanagan, 339 F.3d at 1234
    –35. In that regard, the
    Guidelines instruct that a defendant’s base offense level “shall be determined on
    12
    the basis of . . . all acts and omissions committed.” U.S.S.G. § 1B1.3(a)(1)(A)
    (emphases added); see United States v. Dewberry, 
    790 F.3d 1022
    , 1034 (10th Cir.
    2015) (“The Guidelines authorize a sentencing court to consider ‘relevant
    conduct’ in determining a defendant’s base offense level.”). Commentary by the
    Sentencing Commission 5 also indicates that:
    The principles and limits of sentencing accountability under this
    guideline [i.e., the relevant-conduct guideline] are not always the
    same as the principles and limits of criminal liability. . . . [T]he
    focus is on the specific acts and omissions for which the
    defendant is to be held accountable in determining the applicable
    guideline range, rather than on whether the defendant is
    criminally liable for an offense as a principal, accomplice, or
    conspirator.
    U.S.S.G. § 1B1.3 cmt. n.1 (emphasis added).
    Indeed, it has been clear for some time that even “a jury’s verdict of
    acquittal does not prevent the sentencing court from considering conduct
    underlying the acquitted charge . . . .” United States v. Watts, 
    519 U.S. 148
    , 157
    (1997) (per curiam) (emphasis added); accord United States v. Lujan, 
    603 F.3d 850
    , 856 (10th Cir. 2010). “This result follows from the difference between the
    standard of proof at trial and the standard of proof at sentencing.” United States
    v. Mendez-Zamora, 
    296 F.3d 1013
    , 1019 (10th Cir. 2002) (citing Watts, 
    519 U.S. 5
                 “[C]ommentary in the Guidelines Manual that interprets or explains a
    guideline is authoritative unless it violates the Constitution or a federal statute, or
    is inconsistent with, or a plainly erroneous reading of, that guideline.” Stinson v.
    United States, 
    508 U.S. 36
    , 38 (1993); accord United States v. Evans, 
    782 F.3d 1115

    136 S. Ct. 171
    (2015).

    at 155). Specifically, the evidentiary standard applicable to a jury’s verdict is
    proof beyond a reasonable doubt, whereas the standard applicable to a sentencing
    court’s determination of the facts is proof by a preponderance of the evidence.

    408 F.3d 672
    , 684 (10th Cir. 2005) (“Both before and under
    the Guidelines, facts relevant to sentencing have generally been found by a
    preponderance of the evidence.”).
    b
    Having detailed the framework within which the district court was
    obligated to sentence Mr. Sadler, we discern no procedural error. The court
    applied the cross-reference provision of U.S.S.G. § 2X1.1 to find that the proper
    base offense level was supplied by U.S.S.G. § 2A4.1—the kidnapping
    guideline—which yielded a base offense level of thirty-two, as the PSR noted. In
    doing so, the court made specific findings of fact that pertained to the offense of
    kidnapping:
    [T]he evidence in support of this cross-reference came in at trial
    with the testimony of Alicia Klein testifying to what the
    defendant said to her and how he acted at the time. She testified
    that the defendant said that “This is a hostage situation.” [Her]
    demeanor at trial reinforced the point that she felt terrorized by
    the events that occurred. And the fact that she came back in the
    house after she was initially pushed out is of little consequence
    because it was at that time that she was back in the house that the
    gun appeared, as argued by the Government, and so . . . the
    significant time in considering this cross-reference is when the
    defendant was in possession of the firearm and what he said and
    14
    did at that point in time . . . . Certainly the events before show
    that this situation had escalated and then when Ms. Klein came
    back into the residence it’s the Court’s conclusion that it
    escalated yet again with the confinement of Ms. Klein and the
    threats applied by the defendant.
    R., Vol. 4, at 337–38 (emphases added). The court then found that “the pistol
    was . . . tapped against [Ms. Klein’s] head” and “was not only carried into the
    bedroom, but . . . was placed within reach and referred to by the defendant.” 
    Id. at 338.
    Moreover, the court acknowledged and accepted Corporal Pownall’s
    testimony “that [Ms. Klein’s] initial response to the suggestion of having sex
    [with Mr. Sadler] was rejection.” 
    Id. The court
    deemed it “clear” from the
    “course of testimony at trial that Ms. Klein was worried and scared throughout the
    course of the events,” 
    id., concluding that
    the PSR was correct in its finding that
    Mr. Sadler unlawfully confined Ms. Klein in Craig’s residence, see 
    id. at 338–39
    (accepting cross-referencing and sentencing enhancements of PSR); see also PSR,
    ¶ 14, at 37 (“[W]hile the defendant was preventing [Ms. Klein] from leaving the
    residence, he was also pushing her to have sex. She advised she ultimately gave
    in and had sex with the defendant, but only because he had the gun and she was
    scared.”).
    All of these findings made on the record at sentencing easily demonstrate
    that the district court properly found by a preponderance of the evidence that Mr.
    Sadler unlawfully confined and sexually assaulted Ms. Klein. Thus, the court was
    15
    correct to utilize the cross-referencing mechanism, which “merely allow[ed] the
    sentence for the charged crime—in this case illegal gun possession—to reflect the
    reality of the crime.” 
    Willis, 925 F.2d at 361
    . Contrary to Mr. Sadler’s view, the
    court was not required to accept his rendition of the evidence at sentencing to
    determine the true nature of the offense—or, for that matter, to entertain his
    unsupported averment that “contradictions and holes . . . can be drawn” from the
    sentencing-hearing testimony. Aplt. Opening Br. at 28. We have said that “the
    district court’s determination of a witness’s credibility at a sentencing hearing is
    ‘virtually unreviewable on appeal,’” United States v. Virgen-Chavarin, 
    350 F.3d 1122
    , 1134 (10th Cir. 2003) (quoting United States v. Jones, 
    160 F.3d 473
    , 480
    (8th Cir. 1998)), and we have no reason to disturb the court’s determinations here.
    In sum, we conclude that the district court applied the cross-referencing
    provision in a manner fully permissible by our circuit precedent. We reject Mr.
    Sadler’s overaching argument that the court procedurally erred by employing the
    cross-referencing mechanism without finding the substantive-offense facts (i.e.,
    those supporting utilization of the kidnapping guideline) beyond a reasonable
    doubt.
    2
    Next, Mr. Sadler insists that the district court flouted the Supreme Court’s
    instructions in Apprendi v. New Jersey, 
    530 U.S. 466
    (2000), Alleyne v. United
    States, --- U.S. ----, 
    133 S. Ct. 2151
    (2013), and Descamps v. United States, ---
    16
    U.S. ----, 
    133 S. Ct. 2276
    (2013). He believes that, by virtue of these decisions,
    the Supreme Court has admonished sentencing courts not to cross-reference under
    the Guidelines as the district court did here. We disagree.
    Specifically, Mr. Sadler opines that Apprendi, Alleyne, and Descamps
    illuminate that the district court’s mode of calculation “crossed the line” of
    judicial discretion, Aplt. Opening Br. at 19, because that calculus produced a
    sentence “based on judicially-determined facts,” 
    id. at 16.
    He contends in that
    vein that “[t]raditional notions of due process,” as set forth in these decisions of
    the Court, require “every element of an [offense] [to] be proved beyond [a]
    reasonable doubt, not [by a] preponderance of the evidence.” 
    Id. at 17.
    More to the point, Mr. Sadler suggests that these authorities forbade the
    district court from finding by a preponderance of the evidence that his underlying
    conduct on the night in question constituted kidnapping. He argues that this is so
    because, under Apprendi and its progeny, any fact that increases a defendant’s
    maximum sentence is considered an element of the charged offense that must be
    proven to a jury—and, in his view, “the cross-referencing guideline enhances a
    statutory maximum sentence of felon in possession,” Aplt. Opening Br. at 18, in
    violation of these cases. However, Mr. Sadler is mistaken.
    Apprendi is wholly inapposite to his circumstances because we have
    “applied Apprendi only where a sentencing court ha[s] imposed a sentence above
    the statutory maximum permitted by the statute of conviction, regardless of what
    17
    fact finding the court, rather than the jury, conducted to impose a sentence within
    that statutory maximum.” United States v. Price, 
    400 F.3d 844
    , 847 (10th Cir.
    2005). Stated otherwise, “Apprendi does not apply to sentencing factors that
    . . . do not increase the statutory maximum.” United States v. Fredette, 
    315 F.3d 1235
    , 1245 (10th Cir. 2003). Here, it is pellucid that the district court’s cross-
    referencing did not increase Mr. Sadler’s statutory-maximum sentence. Mr.
    Sadler was sentenced to serve 120 months in prison—the maximum sentence
    allowed by statute—which is patently at least 240 months below what he would
    have received under the advisory Guidelines range but for that statutory limit.
    The district court’s cross-referencing did not have the effect of elevating in any
    way the applicable statutory maximum. Therefore, Mr. Sadler’s circumstances
    fall outside the realm of scenarios contemplated by Apprendi.
    Second, by their own terms, the remaining cases upon which Mr. Sadler
    relies undermine his argument that a jury was required to find facts supporting the
    offense of kidnapping beyond a reasonable doubt. Notably, the Supreme Court
    spoke directly to this point in Alleyne as follows:
    In holding that facts that increase mandatory minimum sentences
    must be submitted to the jury, we take care to note what our
    holding does not entail. Our ruling today does not mean that any
    fact that influences judicial discretion must be found by a jury.
    We have long recognized that broad sentencing discretion,
    informed by judicial factfinding, does not violate the Sixth
    Amendment. See, e.g., Dillon v. United States, 560 U.S. [817,
    828–29] (2010) (“[W]ithin established limits[,] . . . the exercise
    of [sentencing] discretion does not contravene the Sixth
    18
    Amendment even if it is informed by judge-found facts”
    (emphasis deleted and internal quotation marks omitted));
    
    Apprendi, 530 U.S. at 481
    (“[N]othing in this history suggests
    that it is impermissible for judges to exercise discretion—taking
    into consideration various factors relating both to offense and
    offender—in imposing a judgment within the range prescribed by
    statute”).
    
    Alleyne, 133 S. Ct. at 2163
    (second through fifth alterations in original).
    We have discerned “no error in [sentencing] procedure under Alleyne”
    when “nothing in the record indicates the district court increased [the]
    [d]efendant’s statutory sentencing range or otherwise altered his legally
    prescribed punishment.” United States v. Cassius, 
    777 F.3d 1093
    , 1097 (10th
    Cir.), cert. denied, --- U.S. ----, 
    135 S. Ct. 2909
    (2015); see United States v. Zar,
    
    790 F.3d 1036
    , 1054–55 (10th Cir.) (“The defendants’ reliance on Apprendi and
    Alleyne is misplaced as none of the defendants were . . . sentenced beyond the
    statutory maximums for their convictions.”), cert. denied, --- U.S. ----, 
    136 S. Ct. 562
    (2015). That is certainly true here.
    Finally, we understand Mr. Sadler to invoke Descamps for the proposition
    that the Supreme Court has proscribed “sentencing courts [from] making findings
    of fact that properly belong to juries.” Aplt. Opening Br. at 19 (quoting
    
    Descamps, 133 S. Ct. at 2287
    ). Yet, the language of Descamps upon which Mr.
    Sadler relies must be placed in proper context; when this happens, it is apparent
    that he is misguided. In the relevant passage in Descamps, the Court was
    discussing the categorical approach to statutory interpretation (i.e., a legal
    19
    principle that is patently outside the scope of this appeal) and explaining why that
    approach was legally sound. The Court stated that this was so because “[the]
    elements-centric, ‘formal categorical approach’ . . . avoids the Sixth Amendment
    concerns that would arise from sentencing courts’ making findings of fact that
    properly belong to juries”—which, as relevant there, were findings of fact
    regarding prior convictions. 
    Descamps, 133 S. Ct. at 2287
    (quoting Taylor v.
    United States, 
    495 U.S. 575
    , 600 (1990)). This language does not speak to the
    district court’s sentencing calculus in Mr. Sadler’s case, and it certainly does not
    announce a rule that sentencing courts cannot make findings of fact.
    Ultimately, we find it beyond peradventure that these three Supreme Court
    decisions do not stand for the proposition that a district court may not make
    findings of fact by a preponderance of the evidence when sentencing a defendant
    within the statutory range. And Mr. Sadler offers no legally cogent reason for
    concluding otherwise. Therefore, we reject his contention that Supreme Court
    precedent demonstrates that his sentence is procedurally unreasonable.
    3
    Mr. Sadler also claims that his sentence is procedurally unreasonable
    because the district court “relie[d] on clearly erroneous facts,” Aplt. Opening Br.
    at 13 (quoting 
    Haley, 529 F.3d at 1311
    ), when it allowed Corporal Pownall to
    testify regarding Ms. Klein’s account of the crime at the sentencing hearing.
    Although Mr. Sadler does not identify with specificity the purportedly
    20
    objectionable testimony, he avers that the court’s consideration of Corporal
    Pownall’s testimonial hearsay statements (i.e., statements concerning what Ms.
    Klein told the officer) trenched upon his Sixth Amendment “right to confront [a]
    complaining witness.” 
    Id. at 30.
    He wisely acknowledges that he did not present
    this argument to the district court and that our review is consequently limited to
    an assay for plain error. See United States v. Olano, 
    507 U.S. 725
    , 731 (1993);
    United States v. Rosales-Miranda, 
    755 F.3d 1253
    , 1257–58 (10th Cir. 2014).
    In order to “successfully run the gauntlet created by our rigorous
    plain-error standard of review,” United States v. McGehee, 
    672 F.3d 860
    , 866
    (10th Cir. 2012), Mr. Sadler must demonstrate: “(1) an error, (2) that is plain,
    which means clear or obvious under current law, and (3) that affects substantial
    rights. If he satisfies these criteria, this Court may exercise discretion to correct
    the error if [4] it seriously affects the fairness, integrity, or public reputation of
    judicial proceedings,” United States v. Cooper, 
    654 F.3d 1104
    , 1117 (10th Cir.
    2011) (quoting United States v. Goode, 
    483 F.3d 676
    , 681 (10th Cir. 2007)). This
    standard is “difficult to overcome,” United States v. Frost, 
    684 F.3d 963
    , 971
    (10th Cir. 2012), and Mr. Sadler’s challenge does not even survive the first step
    because he cannot establish that the district court erred at all.
    According to Mr. Sadler, the district court’s consideration of sentencing-
    hearing testimony from Corporal Pownall regarding Ms. Klein’s allegations of
    sexual assault violated the Sixth Amendment’s Confrontation Clause as construed
    21
    in Crawford v. Washington, 
    541 U.S. 36
    (2004). The rule set forth in Crawford is
    that testimonial hearsay is inadmissible at trial unless the declarant is unavailable
    and the defendant had an earlier opportunity to cross-examine the declarant. 
    See 541 U.S. at 68
    ; accord Ohio v. Clark, --- U.S. ----, 
    135 S. Ct. 2173
    , 2179 (2015);
    United States v. Summers, 
    414 F.3d 1287
    , 1298–99 (10th Cir. 2005). Stated
    otherwise, we have said that “[t]he upshot [of Crawford] is that the
    [Confrontation] [C]lause ‘constitute[s] an absolute bar to the admissibility of a
    testimonial hearsay statement where the declarant was unavailable to testify at
    trial and the defendant had no prior opportunity to cross-examine the declarant.’”
    United States v. [Richard] Clark, 
    717 F.3d 790
    , 815 n.15 (10th Cir. 2013) (fifth
    alteration in original) (quoting United States v. Smalls, 
    605 F.3d 765
    , 774 (10th
    Cir. 2010)).
    Importantly, Crawford enunciated a trial right, not a sentencing right. See
    United States v. Battles, 
    745 F.3d 436
    , 462 (10th Cir.), cert. denied, --- U.S. ----
    , 
    135 S. Ct. 355
    (2014). As we have interpreted the Supreme Court’s Crawford
    decision, it “concerned the use of testimonial hearsay statements at trial and does
    not speak to whether it is appropriate for a court to rely on hearsay statements at a
    sentencing hearing.” United States v. Bustamante, 
    454 F.3d 1200
    , 1202 (10th Cir.
    2006); accord 
    Battles, 745 F.3d at 462
    . As such, we have been able to remain
    22
    faithful to “our [pre-Crawford] precedent [6] ‘that constitutional provisions
    regarding the Confrontation Clause are not required to be applied during
    sentencing proceedings.’” 
    Bustamante, 454 F.3d at 1202
    (quoting United States
    v. Hershberger, 
    962 F.2d 1548
    , 1554 (10th Cir. 1992)). The opinions of our sister
    circuits that have considered confrontation rights during sentencing proceedings
    also support the conclusion that we reach here—viz., that Mr. Sadler’s Crawford
    argument is unavailing. See, e.g., United States v. Isom, 
    635 F.3d 904
    , 907–08
    (7th Cir. 2011); United States v. Dyer, 
    589 F.3d 520
    , 532 (1st Cir. 2009); United
    States v. Ingham, 
    486 F.3d 1068
    , 1076 (9th Cir. 2007); United States v. Brown,
    
    430 F.3d 942
    , 944 (8th Cir. 2005); United States v. Martinez, 
    413 F.3d 239
    , 243
    (2d Cir. 2005).
    Further, in a post-Crawford case bearing many similarities to Mr.
    Sadler’s—most saliently, involving a cross-reference to kidnapping for a
    convicted felon in possession—a panel of this court discerned no procedural error
    when the district court considered hearsay statements from the alleged victim
    during sentencing. See United States v. McGuffin, 149 F. App’x 714, 718–19
    6
    See, e.g., United States v. Beaulieu, 
    893 F.2d 1177
    , 1180 (10th Cir.
    1990) (“The Supreme Court has made clear that the constitutional requirements
    mandated in a criminal trial as to confrontation and cross-examination do not
    apply at non-capital sentencing proceedings.” (footnote omitted)); United States
    v. Sunrhodes, 
    831 F.2d 1537
    , 1543 (10th Cir. 1987) (“[T]he requirements
    mandated in a criminal trial as to confrontation and cross-examination are not
    applicable at sentencing proceedings. The right to confrontation is basically a
    trial right.”)
    23
    (10th Cir. 2005). The panel noted that “the Guidelines allow a sentencing court
    to consider all relevant information ‘without regard to its admissibility under the
    rules of evidence applicable at trial, provided that the information has sufficient
    indicia of reliability to support its probable accuracy.’” 
    Id. at 719
    (quoting
    U.S.S.G. § 6A1.3(a)). It ultimately discerned no violation of the defendant’s
    Confrontation Clause rights as construed by Crawford. Applying McGuffin’s
    logic, we reach the same conclusion regarding Mr. Sadler’s challenge. 7
    In sum, we cannot say that the sentencing court committed any error at all,
    let alone error that would have been clear or obvious under current law. We
    therefore hold that this Confrontation Clause challenge fails under our plain-error
    7
    Mr. Sadler does not appear to challenge the admission of hearsay
    evidence per se at his sentencing proceeding. Even if his briefing could
    conceivably be read to include such a challenge, we would easily hold that it is
    meritless. Hearsay evidence bearing even minimal indicia of reliability is
    perfectly proper during sentencing proceedings. See United States v. Damato,
    
    672 F.3d 832
    , 847 (10th Cir. 2012) (noting that “we have consistently” permitted
    the consideration of hearsay at sentencing “if [the statements] bear some minimal
    indicia of reliability” (emphasis added) (quoting 
    Cook, 550 F.3d at 1296
    )); see
    also United States v. Ruby, 
    706 F.3d 1221
    , 1227 (10th Cir. 2013) (“Unlike at a
    criminal trial where the Federal Rules of Evidence limit the types of admissible
    evidence, at a sentencing hearing the court can have access to any relevant
    information, as long as it adheres to a preponderance of the evidence standard.
    Sentencing courts historically rely on a wide array of information relevant to the
    individualized needs of the offender, including hearsay evidence . . . .” (citation
    omitted)). And it is palpable from our review of the record that the hearsay
    evidence admitted here bore adequate indicia of reliability.
    24
    standard. And, having duly rejected all of Mr. Sadler’s averments of procedural
    error, we conclude that his sentence is procedurally reasonable. 8
    B
    Mr. Sadler also charges that the sentence he received was greater than
    necessary to serve the purposes of sentencing. 9 “A sentence is substantively
    unreasonable if the length of the sentence is unreasonable given the totality of the
    8
    Although Mr. Sadler nominally disputes the court’s two upward
    adjustments from the base offense level under the Guidelines—i.e., for use of a
    dangerous weapon and sexual exploitation of the victim—we note that the
    challenge to these increases is identical to the one he lodges regarding the base
    offense level cross-referencing. For the reasons we have already provided, we
    conclude that the district court did not commit clear error in accepting these two
    sentencing enhancements, and we reject Mr. Sadler’s invitation to reverse on that
    basis.
    9
    Mr. Sadler’s opening brief borders on inadequate because his only
    statements concerning substantive reasonableness are (1) that “[a] sentence is
    substantively unreasonable if the length ‘is unreasonable given the totality of the
    circumstances in light of [the] 18 U.S.C. § 3553(a) factors,’” Aplt. Opening Br. at
    13 (quoting 
    Haley, 529 F.3d at 1311
    ), and (2) cursory mentions in his table of
    contents and summary of the issues. In other words, he presents his appellate
    arguments without citations to the record for supporting facts or reasons for his
    contentions. See Fed. R. App. P. 28(a)(8); see Garrett v. Selby Connor Maddux &
    Janer, 
    425 F.3d 836
    , 841 (10th Cir. 2005) (“Under Rule 28, . . . a brief ‘must
    contain[ ] more than a generalized assertion of error . . . .’” (quoting Anderson v.
    Hardman, 
    241 F.3d 544
    , 545 (7th Cir. 2001))); Utahns for Better Transp. v. U.S.

    305 F.3d 1152
    , 1175 (10th Cir. 2002) (“We do not consider
    merely including an issue within a list to be adequate briefing.”). We may deem
    such appellate issues waived if they are insufficiently briefed. See Bronson v.
    Swensen, 
    500 F.3d 1099
    , 1105 (10th Cir. 2007); Adler v. Wal-Mart Stores, Inc.,
    
    144 F.3d 664
    , 679 (10th Cir. 1998). Nonetheless, in the exercise of our
    discretion, we have reviewed the merits of Mr. Sadler’s substantive-
    reasonableness challenge. See 
    Garrett, 425 F.3d at 840

    of appeals may still address issues raised in inadequate briefing).

    . We review the sentence imposed under a deferential abuse-of-discretion
    standard. See 
    Rita, 551 U.S. at 350
    –51; United States v. Shuck, 
    713 F.3d 563
    ,
    570 (10th Cir. 2013). Consequently, “we will ‘deem a sentence [substantively]
    unreasonable only if it is arbitrary, capricious, whimsical, or manifestly
    unreasonable.’” 
    Lente, 759 F.3d at 1158
    (quoting United States v. Gantt, 
    679 F.3d 1240
    , 1249 (10th Cir. 2012)).
    In our analysis, however, we presume a sentence to be substantively
    reasonable if it falls within the properly calculated advisory Guidelines range.
    See United States v. Sanchez-Leon, 
    764 F.3d 1248
    , 1267 (10th Cir. 2014); United
    States v. Chavez, 
    723 F.3d 1226
    , 1233 (10th Cir. 2013). We have “extend[ed] the
    rebuttable presumption of reasonableness to a below-guideline sentence
    challenged by the defendant as unreasonably harsh.” United States v. Balbin-
    10
    More specifically, these factors include:
    the nature and circumstances of the offense; the history
    and characteristics of the defendant; the need for the
    sentence imposed to afford adequate deterrence, protect
    the public, and provide the defendant with needed
    educational or vocational training, medical care or other
    correctional treatment in the most effective manner;
    pertinent guidelines; pertinent policy statements; the need
    to avoid unwanted sentence disparities; and the need to
    provide restitution.

    , 1242 n.3 (10th Cir. 2005)
    (citing 18 U.S.C. § 3553(a)).

    Mesa, 
    643 F.3d 783
    , 788 (10th Cir. 2011); accord United States v. Trent, 
    767 F.3d 1046
    , 1051 (10th Cir. 2014); see also United States v. Zaavedra, 590 F.
    App’x 828, 829 (10th Cir. 2015) (noting that “[a] statutory maximum sentence
    that is below the Guidelines range is functionally equivalent to a
    within-Guidelines sentence and is entitled to a presumption of reasonableness.”
    (citing United States v. Johnson, 
    445 F.3d 793
    , 798 (5th Cir. 2006))).
    “[T]he presumption of reasonableness ‘is a deferential standard that either
    the defendant or the government may rebut by demonstrating that the sentence is
    unreasonable when viewed against the other factors delineated in [18 U.S.C.]
    3553(a).’” United States v. Tindall, 
    519 F.3d 1057
    , 1066 (10th Cir. 2008)
    (quoting United States v. Kristl, 
    437 F.3d 1050
    , 1054 (10th Cir. 2006)). As
    germane here, we have concluded that the district court committed no procedural
    error in calculating Mr. Sadler’s advisory Guidelines range, and his ultimate
    sentence is well below that advisory range due to the ceiling established by the
    statutory maximum for his offense. See U.S.S.G. § 5G1.1(a). Accordingly, Mr.
    Sadler’s sentence is entitled to a presumption of reasonableness. Mr. Sadler thus
    bears the burden of convincing us otherwise; that is, he must explain why his
    sentence is “unreasonable when viewed in light of the § 3553(a) factors, i.e.,
    sentencing’s substantive component.” United States v. Grigsby, 
    749 F.3d 908
    ,
    910 (10th Cir.), cert. denied, --- U.S. ----, 
    135 S. Ct. 214
    (2014). This he has not
    done. Mr. Sadler’s failure to discuss the ostensible unreasonableness of his
    27
    sentence in light of the § 3553(a) factors sounds the death knell for his
    substantive-reasonableness challenge. 11 Accordingly, we have no occasion to
    disturb the district court’s imposition of a sentence of 120 months.
    III
    For the reasons discussed above, we AFFIRM the judgment of the district
    court.

    In any event, our thorough review of the record leaves us with no
    reason to question the substantive reasonableness of the court’s sentence.
    Notably, the court properly weighed the sentencing factors, particularly insofar as
    those factors bear on “the nature and circumstances of the offense and the history
    and characteristics of the defendant,” 18 U.S.C. § 3553(a)(1), and “the need for
    the sentence imposed . . . to reflect the seriousness of the offense” and to deter
    future criminal conduct and “protect the public,” 
    id. § 3553(a)(2).
