    Before HARTZ, HOLMES, and BACHARACH, Circuit Judges.
    HOLMES, Circuit Judge.
    After planting a bomb near a gas pipeline, Daniel Herriman voluntarily
    turned himself in to the authorities and confessed. When he was criminally
    charged for his conduct, he pleaded not guilty and presented a defense to the jury
    based on his mental illness. Unpersuaded, the jury voted to convict him. Mr.
    Herriman then sought a downward adjustment to his sentence under § 3E1.1 of
    the U.S. Sentencing Guidelines (“U.S.S.G.” or “Guidelines”) on the ground that
    he had accepted responsibility for his actions. The district court declined to make
    the adjustment. Mr. Herriman now appeals from that decision, which we review
    under the jurisdiction conferred by 
    28 U.S.C. § 1291
    . The district court did not
    abuse its discretion in denying the requested adjustment, and we consequently
    affirm the court’s sentence.
    I
    On August 10, 2011, an explosive device was discovered near a gas
    pipeline in Okemah, Oklahoma. When Mr. Herriman saw the bomb reported on
    the news, he called the police and informed them that he was responsible. Law
    enforcement interviewed Mr. Herriman, and he offered details relating to the
    bomb, including what materials he had used and where they could be located in
    his home.
    Based on this information and the ensuing investigation, the government
    charged Mr. Herriman with attempting to destroy or damage property by means of
    an explosive, in violation of 
    18 U.S.C. § 844
    (i), and illegally making a
    destructive device, in violation of 
    26 U.S.C. §§ 5861
    (f), 5822, and 5871. The
    2
    district court became concerned at the preliminary and detention hearings that Mr.
    Herriman was potentially incompetent to stand trial. As a result, it ordered a
    mental evaluation to determine “whether he [was] suffering from a mental disease
    or defect rendering him mentally incompetent.” R., Vol. I, at 20 (Order, filed
    Aug. 18, 2011). Pursuant to that order, Jeremiah Dwyer, Ph.D., a forensic
    psychologist employed by the Bureau of Prisons, examined Mr. Herriman and
    found no objective evidence that his mental-health condition “would impair his
    present ability to understand the nature and consequences of the court proceedings
    against him, or his ability to properly assist counsel in his defense.” 
    Id.,
     Vol. III,
    at 36 (Forensic Evaluation, dated Oct. 11, 2011). The court accepted Dr. Dwyer’s
    conclusion and ruled that Mr. Herriman was fit to stand trial. A jury trial was
    scheduled, and Mr. Herriman gave notice that he would be asserting an insanity
    defense.
    During trial, in its case-in-chief, the government naturally elicited
    testimony to prove that Mr. Herriman had engaged in the charged conduct, i.e.,
    that he had constructed and placed the explosive device. Defense counsel almost
    entirely declined to contest the description of Mr. Herriman’s actions offered by
    the government’s witnesses.
    When the government rested its case, Mr. Herriman cursorily and
    unsuccessfully moved for a judgment of acquittal pursuant to Federal Rule of
    Criminal Procedure 29. The defense then called a series of witnesses to testify to
    3
    Mr. Herriman’s psychological problems and his mental condition at the time of
    the incident. Their accounts overlap in large measure, and there is no need to
    recite each individual’s remarks in detail. It suffices for our purposes to describe
    the overall narrative conveyed by the defense’s witnesses. According to that
    narrative, Mr. Herriman had several mental-health problems—specifically, manic
    depression, schizoaffective disorder, and post-traumatic stress disorder; the last of
    these was caused by sexual abuse Mr. Herriman suffered as a minor. Mr.
    Herriman’s symptoms included a tendency to hallucinate voices inside his head.
    Some of those voices were “command hallucinations,” i.e., “voices [that] actually
    instruct [one] to do things.” 
    Id.,
     Vol. II, at 819 (Trial Tr., dated May 9–14,
    2012).
    When he was thirteen years old, Mr. Herriman attempted to take his own
    life, and he has been hospitalized repeatedly for psychotic episodes. Mr.
    Herriman was deeply shaken by the suicide of his mother and by the death of his
    sister, which may also have been a suicide. Mr. Herriman’s mental condition
    worsened after he moved into his sister’s home, where he had seen her dead body.
    Psychiatrists had prescribed medications for Mr. Herriman’s mental issues, but
    the medications did not always work. More specifically, the medications did not
    always subdue the voices in Mr. Herriman’s head. At the time of the incident
    leading to his charged crimes, Mr. Herriman was taking antipsychotic medications
    for his manic depression and for his psychosis and was seeing a psychiatrist
    4
    regularly.
    Under the narrative Mr. Herriman advanced at trial, his mental condition
    was exacerbated in August 2011 due to the anniversary of his mother’s death,
    which had taken place that same month. In his unstable state, Mr. Herriman
    planted the bomb at the behest of the imaginary voices that spoke to him. The
    voices, which “identified themselves as al Qaeda,” 
    id. at 830
    , threatened to hand
    Mr. Herriman over to the individuals who had sexually abused him in his youth if
    he disobeyed. At the time he built and planted the bomb, Mr. Herriman was
    affected by his delusions to such an extent that he was not aware of what he was
    doing and could not distinguish between right and wrong. When he heard a story
    on the news about the bombing, he “became lucid,” 
    id. at 655
    , and, realizing what
    he had done, immediately called the police and took responsibility for his actions.
    Without any solicitation from law enforcement, Mr. Herriman volunteered every
    detail relating to the bomb, including what materials he had used and where they
    were located in his residence. In so doing, he effectively solved the crime and
    saved the authorities from having to conduct any investigation.
    Rejecting Mr. Herriman’s defense, the jury convicted him of both charged
    offenses. The Presentence Investigation Report (“PSR”) that followed stated that
    Mr. Herriman “maintained his innocence by reason of insanity throughout these
    proceedings. Therefore, he is not entitled to an adjustment [for acceptance of
    5
    responsibility] under the provisions of [U.S.S.G. §] 3E1.1.” 1 Id., Vol. III, at 67
    (PSR, filed Nov. 5, 2012). 2
    Mr. Herriman objected to the recommendation, arguing at the sentencing
    hearing “that it was an irresistible impulse that caused [the crime] to happen.”
    Id., Vol. II, at 317 (Sentencing Tr., dated Dec. 5, 2012). In elaboration, defense
    counsel explained that “under the law it would have been improper for Mr.
    Herriman to stand in front of a court and plead guilty because there was a true
    question of whether he possessed the necessary intent.” Id. at 317–18. Thus, the
    fact that Mr. Herriman pleaded not guilty and went to trial did not, in defense
    counsel’s eyes, overshadow the fact that he called law enforcement “out of the
    blue” and “solved their crime for them.” Id. at 318. The government responded
    that by “contesting the issue of intent by raising the defense of insanity [Mr.
    Herriman] [was] contesting a factual issue[,] . . . requiring the government to go
    to trial,” and he had thereby lost any rightful claim to the acceptance-of-
    responsibility reduction. Id. at 319.
    Having heard the parties’ respective positions, the district court overruled
    Mr. Herriman’s objection and declined to apply the acceptance-of-responsibility
    1
    In preparing the PSR, the U.S. Probation Office used the 2011
    version of the Guidelines. Neither party disputes its decision to do so, and we
    will therefore rely on the same version.
    2
    Initially, the PSR advised the district court to apply the reduction,
    but the probation officer who drafted the report changed her mind upon the
    government’s objection and reversed her recommendation to the district court.
    6
    adjustment. It reasoned as follows:
    One of the elements that the government was required to prove
    at trial was that the defendant committed the offenses knowingly
    and intentionally. By raising insanity as an affirmative defense,
    the defendant’s denial of his intentionality and knowingly
    committing the offenses directly challenges one of the elements
    of guilt. Therefore, the defendant is not eligible for reduction
    [for] acceptance of responsibility in this case.
    Id. at 322–23. In light of its ruling, the district court sentenced Mr. Herriman to
    sixty-three months in prison on each of the two counts of the indictment, to be
    served concurrently, followed by three years of supervised release. Mr. Herriman
    timely appealed his sentence to our court.
    II
    On appeal, Mr. Herriman attacks the district court’s refusal to apply the
    acceptance-of-responsibility adjustment in two related respects: (1) the district
    court committed reversible error by denying the adjustment; and (2) the district
    court committed reversible error by failing to offer any factual findings to
    supports its decision. As explained below, both arguments are foreclosed by our
    binding precedent, and we are therefore compelled to reject them and affirm the
    sentence imposed by the district court.
    A
    Mr. Herriman urges us to reverse the district court on the basis that it
    improperly refused to adjust his sentence downward to reflect his acceptance of
    responsibility, as permitted by U.S.S.G. § 3E1.1, and that it found insufficient
    7
    facts to warrant that refusal. “Our overall standard of review is abuse of
    discretion.” United States v. Lopez-Avila, 
    665 F.3d 1216
    , 1218 (10th Cir. 2011).
    More specifically, both of Mr. Herriman’s contentions must be analyzed under the
    rubric of procedural error. See United States v. McGehee, 
    672 F.3d 860
    , 874
    (10th Cir. 2012) (deeming a challenge to the district court’s denial of an
    acceptance-of-responsibility adjustment “a claim of procedural error”); United
    States v. Koufos, 
    666 F.3d 1243
    , 1254 (10th Cir. 2011) (“A court may commit
    procedural error in imposing a sentence by . . . ‘failing to adequately explain the
    chosen sentence.’” (quoting Gall v. United States, 
    552 U.S. 38
    , 46 (2007)), cert.
    denied, --- U.S. ----, 
    132 S. Ct. 2787
     (2012).
    Within the specific context of acceptance-of-responsibility adjustments, we
    have acknowledged that “‘[t]he sentencing judge is in a unique position to
    evaluate a defendant’s acceptance of responsibility’ and ‘is entitled to great
    deference on review.’” 3 United States v. Collins, 
    511 F.3d 1276
    , 1280–81 (10th
    Cir. 2008) (alteration in original) (quoting United States v. Hamilton, 
    413 F.3d 1138
    , 1145 (10th Cir. 2005)); see United States v. Melot, 
    732 F.3d 1234
    , 1243–44
    (10th Cir. 2013) (“A district court has wide discretion in determining whether a
    3
    Mr. Herriman proposes a less deferential standard on the ground that
    the district court found inadequate facts in refusing the adjustment. In Part II.C.,
    infra, we reject the premise of this argument, i.e., that the district court’s
    explanation of its sentence was inadequate, so we will proceed to apply the
    deferential standard articulated above.
    8
    defendant qualifies for the acceptance-of-responsibility reduction, and this court
    will not reverse the court’s decision unless it is clearly erroneous.”); see also
    United States v. Sarracino, 
    340 F.3d 1148
    , 1174 (10th Cir. 2003) (noting that a
    sentencing court’s denial of the reduction “should not be disturbed unless it is
    without foundation”). A defendant must prove to the district court “‘by a
    preponderance of the evidence that he is entitled’ to the acceptance of
    responsibility adjustment.” United States v. Benoit, 
    713 F.3d 1
    , 24 (10th Cir.
    2013) (quoting United States v. Portillo-Valenzuela, 
    20 F.3d 393
    , 394 (10th Cir.
    1994)).
    B
    We turn first to Mr. Herriman’s argument that the district court committed
    reversible error when it declined to recognize that he had accepted responsibility
    within the meaning of the Guidelines and thus declined to grant a downward
    adjustment to his sentence. For the reasons that follow, we cannot accept Mr.
    Herriman’s argument and instead conclude that the district court did not abuse its
    discretion in this regard.
    1
    Our analysis begins with the plain language of the sentencing provision at
    issue, and its admonition to district courts that “[i]f the defendant clearly
    demonstrates acceptance of responsibility for his offense,” the sentencing court
    should “decrease the offense level by 2 levels.” U.S.S.G. § 3E1.1(a).
    9
    Application Note 2 to § 3E1.1 brings us even closer to the crux of the dispute, as
    it forms the basis for the district court’s ruling and the grounds for Mr.
    Herriman’s appeal. To quote the Note in full, it clarifies that the acceptance-of-
    responsibility
    adjustment is not intended to apply to a defendant who puts the
    government to its burden of proof at trial by denying the essential
    factual elements of guilt, is convicted, and only then admits guilt
    and expresses remorse. Conviction by trial, however, does not
    automatically preclude a defendant from consideration for such
    a reduction. In rare situations a defendant may clearly
    demonstrate an acceptance of responsibility for his criminal
    conduct even though he exercises his constitutional right to a
    trial. This may occur, for example, where a defendant goes to
    trial to assert and preserve issues that do not relate to factual
    guilt (e.g., to make a constitutional challenge to a statute or a
    challenge to the applicability of a statute to his conduct). In each
    such instance, however, a determination that a defendant has
    accepted responsibility will be based primarily upon pre-trial
    statements and conduct.
    Id. § 3E1.1 cmt. n.2. Reduced to its essence, Mr. Herriman’s thesis is that his
    case represented one of the “rare situations” in which a defendant insists upon a
    trial and yet is still entitled to the benefit of the downward adjustment.
    Only once before in a precedential decision have we upheld a district
    court’s decision to grant an acceptance-of-responsibility adjustment to a
    defendant who forced the government to take its evidence to a jury—specifically,
    United States v. Gauvin, 
    173 F.3d 798
     (10th Cir. 1999). See United States v.
    Alvarez, 
    731 F.3d 1101
    , 1105 (10th Cir. 2013) (characterizing Gauvin as “the one
    case in which we approved [application of § 3E1.1 after trial]” (alteration in
    10
    original) (quoting United States v. Sims, 
    428 F.3d 945
    , 961 (10th Cir. 2005))
    (internal quotation marks omitted)), pet. for cert. filed (U.S. Dec. 30, 2013) (No.
    13-8104).
    The defendant in Gauvin committed an assault while intoxicated. 
    173 F.3d at 801
    . Believing that Mr. Gauvin’s circumstances constituted one of the “rare
    situations” discussed in Application Note 2, the district court adjusted his
    sentence for acceptance of responsibility. See 
    id. at 805
    . The government
    appealed, and we affirmed. “Mr. Gauvin,” we explained, “admitted to all the
    conduct with which he was charged. He simply disputed whether his
    acknowledged factual state of mind met the legal criteria of intent to harm or
    cause apprehension.” 
    Id. at 806
     (emphasis added). Going into further detail, we
    observed that “[w]hile a jury disagreed with Mr. Gauvin’s defense that he lacked
    the requisite intent to commit the crime, that does not undermine the good faith in
    which the district court found this defense was asserted.” 
    Id.
     We emphasized
    that “Mr. Gauvin argued that he did not intend, while drunk and scared, to cause
    injury to others. Further, he contended that his drunkenness rendered him
    incapable of forming the requisite mens rea.” 
    Id.
    For all intents and purposes, as we saw it, Mr. Gauvin’s argument
    represented “essentially a challenge to the applicability of the statute to his
    conduct” and was thus compatible with an adjustment for acceptance of
    responsibility. 
    Id.
     Our analysis then concluded with the caveat that “[a]lthough
    11
    we recognize that such adjustments are ‘rare,’ and [although we] might not have
    reached the same decision [as the district court], in light of the deference afforded
    the sentencing judge, we hold the district court did not err in granting a
    downward [adjustment] for acceptance of responsibility.” 
    Id.
     (citation omitted).
    Since handing down our decision in Gauvin, we have had occasion to
    clarify and refine it. In particular, we have taken care to highlight the importance
    of the deferential standard of review to Gauvin’s holding. That is to say, “in
    Gauvin, we merely accorded the district court the requisite deference in upholding
    its decision to grant the two-level reduction.” McGehee, 
    672 F.3d at 877
    ; cf.
    Benoit, 713 F.3d at 25 (affirming a district court’s refusal to apply the adjustment
    with reference to the deference Gauvin gave to the opposite determination).
    Significantly, “[w]e did not indicate that other sentencing courts would be obliged
    to reach the same conclusion on similar facts.” McGehee, 
    672 F.3d at 877
    ; see
    United States v. Saffo, 
    227 F.3d 1260
    , 1272 (10th Cir. 2000) (“Here, under the
    same principles used in Gauvin that looked to the good faith of the defendant’s
    defense and afforded deference to the sentencing judge’s determination on that
    issue, we hold that the district court did not err in denying [the defendant] a
    downward [adjustment] for acceptance of responsibility.” (emphasis added)).
    Quite to the contrary, “we might well uphold their decisions on similar facts to
    deny the acceptance-of-responsibility adjustment.” McGehee, 
    672 F.3d at 877
    ;
    see United States v. Day, 
    223 F.3d 1225
    , 1231 (10th Cir. 2000) (“Just as we gave
    12
    deference to the district court’s determination in Gauvin, we also give deference
    to the district court’s determination here [that the defendant was not entitled to
    the adjustment] absent any compelling evidence to the contrary.”).
    Furthermore, significantly, we have interpreted Gauvin to allow for
    adjustments only where a “defendant admitted to all the conduct with which he
    was charged but simply disputed whether his acknowledged factual state of mind
    met the legal criteria of intent required by the applicable statute.” United States
    v. Tom, 
    494 F.3d 1277
    , 1281 (10th Cir. 2007) (quoting Sims, 
    428 F.3d at 961
    )
    (internal quotation marks omitted); see McGehee, 
    672 F.3d at 878
     (drawing a
    distinction between Mr. Gauvin, who exercised his constitutional right to a trial
    “only to ‘preserve issues that do not relate to factual guilt,’” and a defendant who
    “declined in significant measure to relieve the government of its burden of
    establishing his factual guilt of the charged offenses” (emphasis added) (quoting
    U.S.S.G. § 3E1.1 cmt. n.2)).
    Understood in this light, Gauvin offers no relief “where defendants have
    challenged the factual element of intent.” See Tom, 
    494 F.3d at 1281
     (emphasis
    added); see also Melot, 732 F.3d at 1244 (deeming the granting of a § 3E1.1
    adjustment clear error where the defendant “did not proceed to trial to preserve an
    issue unrelated to his factual guilt” but rather “exercised his constitutional right to
    trial so he could challenge the mens rea element of the crimes charged in the
    indictment”); Alvarez, 731 F.3d at 1105 (“[W]hile a defendant who proceeds to
    13
    trial to challenge ‘whether [his] acknowledged factual state of mind met the legal
    criteria of intent’ may, in rare cases, be eligible for a § 3E1.1 reduction, a
    defendant who disputes the ‘factual element of intent’ itself will not.” (second
    alteration in original) (quoting Tom, 
    494 F.3d at 1281
    )).
    2
    To distill the foregoing analysis, we conclude that, in light of the operative
    deferential standard of review, Gauvin’s outcome does not dictate the appropriate
    resolution here (and would not do so even if the facts were similar). Therefore,
    we focus instead on the general legal principles embodied in Gauvin and our other
    precedent and conclude that, in order to prevail, Mr. Herriman must demonstrate
    that he only disputed purely legal questions in going to trial and did not contest
    material facts relating to his guilt of the charged offenses. Mr. Herriman has not
    made that showing.
    a
    Putting a finer point on the analysis, the resolution of the question of
    whether Mr. Herriman was entitled to the acceptance-of-responsibility reduction
    turns on the nature of what was disputed between the parties at trial: the fact of
    Mr. Herriman’s mental condition or the legal ramifications of that condition. To
    ascertain the substance of the dispute between the government and the defense
    regarding Mr. Herriman’s mental condition, it is instructive to consider the
    parties’ dueling presentations to the jury.
    14
    Before delving into the trial transcript, a word should be said to clarify the
    terms of our inquiry. Although the line between them is often blurred, a
    challenge to the mens rea element of an offense and the presentation of an
    insanity defense proceed on different procedural paths and implicate distinct
    concepts regarding the mental condition of the defendant. See Stephen J. Morse
    & Morris B. Hoffman, The Uneasy Entente Between Legal Insanity and Mens
    Rea: Beyond Clark v. Arizona, 
    97 J. Crim. L. & Criminology 1071
    , 1072 (2007)
    (“Ever since the affirmative defense of insanity took its first truly modern breath
    . . . its relationship to its cousin, mens rea, has been plagued with confusion.”
    (footnotes omitted)); see generally United States v. Allen, 
    449 F.3d 1121
    ,
    1126–27 (10th Cir. 2006) (exploring the distinction between the two concepts).
    Mens rea is “the mental element of the crime charged.” Clark v. Arizona, 
    548 U.S. 735
    , 742 (2006). As such, the government must prove the mens rea element
    beyond a reasonable doubt. See United States v. Johnson, 
    57 F.3d 968
    , 973 (10th
    Cir. 1995). On the other hand, insanity is an affirmative legal defense a
    defendant must raise and prove by clear and convincing evidence; in particular, a
    defendant must show that “at the time of the commission of the acts constituting
    the offense, the defendant, as a result of a severe mental disease or defect, was
    unable to appreciate the nature and quality of the wrongfulness of his acts.” See
    
    18 U.S.C. § 17
    . See generally Morse & Hoffman, supra, at 1074 (“Even if the
    state can prove all the elements beyond a reasonable doubt, the defendant may
    15
    avoid criminal liability by establishing an affirmative defense of justification or
    excuse.”); id. at 1089–90 (“[E]ven the most delusional or hallucinating person can
    form the requisite mental state. . . . [A] person suffering from auditory
    hallucinations who hears God’s voice command him to kill surely forms the
    intention to kill when he kills in response to the hallucinated command.”
    (footnotes omitted)).
    We need not examine additional distinctions between the two
    concepts—i.e., the mens rea element and the insanity defense. For our purposes,
    the significant point is that both concepts relate to a defendant’s mental condition
    at the time of the offense and both may form the foundation for a defendant’s
    acquittal—either through an identified failure of proof as to the mens rea element
    of the crime or through the affirmative establishment of an insanity defense. See
    id. at 1096–97 (“[T]he mens rea issue is entirely distinct from the legal insanity
    issue, even if precisely the same evidence would be relevant to adjudicating both
    claims. . . . [T]he same evidence that a defendant was delusional may both negate
    mens rea and support a finding of legal insanity, but the questions being answered
    by the evidence are different.” (footnote omitted)). And, from our review of the
    record, it is patent that Mr. Herriman relied on both concepts with the precise
    objective of acquittal in mind. 4

    Although the district court’s analysis in denying Mr. Herriman a

    Specifically, Mr. Herriman’s counsel explained why he went to trial during
    the sentencing proceeding: “[U]nder the law it would have been improper for Mr.
    Herriman to stand in front of a court and plead guilty because there was a true
    question of whether he possessed the necessary intent.” R., Vol. II, at 317–18.
    That is a mens rea argument. 5 See United States v. Brown, 
    326 F.3d 1143
    ,
    1146–47 (10th Cir. 2003) (discussing how a defendant’s mental condition can
    show that he was incapable of having the requisite mens rea to commit the crime).
    As for the insanity defense, it was explicitly presented to the jury. See R., Vol. I,
    at 120 (Jury Instrs., filed May 14, 2012).
    Furthermore, it is also beyond peradventure that Mr. Herriman’s mens rea
    argument and his insanity argument were both related to his guilt. Simply put,
    4
    (...continued)
    downward adjustment for acceptance of responsibility is arguably not entirely
    pellucid in drawing a line of demarcation between the two related concepts of
    mens rea and insanity, we are confident that the court recognized that Mr.
    Herriman’s defense at trial implicated both concepts, and that this defense was
    aimed at producing an acquittal. See R., Vol. II, at 322 (discussing mens rea as
    “[o]ne of the elements that the government was required to prove at trial,” which
    Mr. Herriman’s defense contested, and specifically noting that Mr. Herriman’s
    “raising [of] insanity as an affirmative defense” “directly challenge[d]” his guilt).
    5
    During his closing argument, Mr. Herriman’s counsel at times
    conflated his insanity defense with his mens rea argument. See R., Vol. II, at 995
    (“The law punishes intent. Did the person intend to commit the crime? Because
    if someone does not have the free will, the volitional ability to know what is right
    or wrong, then we as a society don’t punish that person.”); id. at 1007 (“[I]f the
    person doesn’t have mens rea, the thought process, the free will, then he’s not
    guilty by reason of insanity.”). At the very least, the jury and the prosecution
    could have understood Mr. Herriman to be putting both concepts at issue.
    17
    had the jury embraced either argument, it likely would have acquitted Mr.
    Herriman. See id. at 121 (“You should render a verdict of ‘not guilty only by
    reason of insanity’ if you find, by clear and convincing evidence, that the
    defendant was insane when he committed the crime charged.”); United States v.
    Dyke, 
    718 F.3d 1282
    , 1286 (10th Cir.) (reiterating that where “the defendant
    failed to form the necessary mens rea for an offense, he must be acquitted”), cert.
    denied, --- U.S. ----, 
    134 S. Ct. 365
     (2013). 6
    Having concluded that Mr. Herriman raised his mental condition to show
    both that he did not possess the necessary mens rea and that, even if he did, he
    was not guilty by virtue of his insanity, and having resolved that both issues were
    related to Mr. Herriman’s guilt, the only question that remains in our analysis is
    whether the parties agreed to the facts regarding those issues and disputed only
    how the law applied to those facts. See Melot, 732 F.3d at 1244 (deeming the
    granting of a § 3E1.1 adjustment clear error where the defendant “did not proceed
    to trial to preserve an issue unrelated to his factual guilt” (emphasis added));
    6
    The jury instructions listed as an element of the 
    18 U.S.C. § 844
    (i)
    charge that “the defendant acted maliciously,” R., Vol. I, at 102, which the
    instructions defined as “intentionally or with willful disregard of the likelihood
    that damage or injury will result,” 
    id. at 106
    . With respect to the 
    26 U.S.C. § 5861
    (f) charge, the instructions required the jury to find that Mr. Herriman
    “knowingly made a firearm,” 
    id. at 109
    , and defined “knowingly” as “voluntarily
    and intentionally, and not because of mistake or accident,” 
    id. at 112
    . The
    instructions required the government to prove beyond a reasonable doubt “each
    and every essential element constituting the offense[s].” See 
    id. at 98
    .
    18
    McGehee, 
    672 F.3d at 878
     (drawing a distinction between Mr. Gauvin, who
    exercised his constitutional right to a trial “only to ‘preserve issues that do not
    relate to factual guilt,’” and a defendant who “declined in significant measure to
    relieve the government of its burden of establishing his factual guilt of the
    charged offenses” (quoting U.S.S.G. § 3E1.1 cmt. n.2)).
    We can simplify the question even further. Mr. Herriman’s mens rea
    argument and his insanity defense were both based on his mental condition. The
    dispositive question, then, is whether the parties were in agreement regarding the
    facts relating to that condition and the condition’s effects on Mr. Herriman at the
    time of the charged crime. After reviewing the record, we are confident that they
    were not.
    We have already outlined the defense’s straightforward theory regarding
    Mr. Herriman’s mental condition and need not reiterate it at length. Suffice it to
    say, the defense’s theory was that Mr. Herriman was in a profoundly delusional
    state at the time he committed the alleged offense. As demonstrated by the
    following review of the trial transcript, the government took the opposite
    position: it maintained that Mr. Herriman was not in fact delusional or psychotic
    at the time he created the bomb and placed it near the gas pipeline.
    At first, it is true, the government’s case focused on Mr. Herriman’s
    actions rather than his mental condition. But as soon as the defense put on its
    own witnesses to speak to Mr. Herriman’s psychological condition, the
    19
    prosecution took sharp exception to the defense’s narrative. For example, when
    the defense put on Mr. Herriman’s son and ex-wife, the prosecution on cross-
    examination asked a series of questions plainly designed to illustrate Mr.
    Herriman’s cogency and lucidity at the time of the offense. See R., Vol. II, at 667
    (“Your dad didn’t make any wrong turns trying to get to your aunt’s house, did
    he?”); id. (“Isn’t it true that he made it there without any problem[?]”); id. at 668
    (“And I take it your dad didn’t have any problem buying that tire, did he? . . .
    Got his money out and paid for it; is that right?”); id. at 670 (“And is [Mr.
    Herriman] explaining the problems? . . . He’s making sense; right?”); id. at
    769–70 (suggesting that Mr. Herriman’s plan to buy a bicycle to ride ten miles to
    work every day was not outlandish, as the defense had argued); cf. id. at 770–71
    (in response to defense counsel’s discussion of Mr. Herriman’s “obsession with”
    rabbits and goats, asking, “[W]hen he bought a rabbit, did he call it a goat?”).
    Along similar lines, other questions submitted by the government to the
    defense’s witnesses were clearly intended to persuade the jury that Mr.
    Herriman’s mental condition was being adequately treated at the time the bomb
    was made and planted. See id. at 768 (asking Mr. Herriman’s ex-wife whether
    Mr. Herriman was aware “that, if any time he has a problem, he can just call [his
    psychiatrist]; isn’t that correct?”); id. at 785 (“And when he had a problem, he
    would call [his psychiatrist] or he would just come in; is that correct?); id. at 791
    (“Did . . . Mr. Herriman . . . indicate that he was being compliant with his
    20
    medication?”).
    Perhaps most significantly of all, the government pushed back on the
    purported truth of Mr. Herriman’s claim that his construction and planting of the
    bomb was entirely a function of the orders he received from the imaginary voices.
    See id. at 788 (asking Mr. Herriman’s psychiatrist whether, around the time of the
    incident, Mr. Herriman had “indicate[d] to you . . . that he was having any type of
    auditory hallucinations”); id. at 860 (“[T]hat would be very unusual for auditory
    hallucinations to be [so] specific [as to take Mr. Herriman through the steps of
    putting the bomb together]; isn’t that correct?”); id. at 862 (“[I]n reference to how
    to build this bomb, . . . it was his design, and . . . the voices just told him to build
    the bomb; correct?”). In the same vein, the government elicited testimony to
    bolster the notion that Mr. Herriman was not having a psychotic episode when he
    committed the acts for which he was charged. See id. at 789–90 (“When you
    were talking to Mr. Herriman on the 13th of July, did he present any symptoms of
    someone who was having a manic episode? . . . Did you observe any behavior
    which would give you the impression that Mr. Herriman was having some sort of
    serious depressed episode?”).
    The government painted a similarly positive picture of Mr. Herriman’s
    mental condition through its two rebuttal witnesses. The first, a physician’s
    assistant who observed Mr. Herriman shortly before he deposited the bomb, was
    called solely to testify that Mr. Herriman did not appear to be in a manic
    21
    condition at the time. Following the physician’s assistant’s testimony, the
    government called Dr. Dwyer (i.e., the psychologist employed by the Bureau of
    Prisons). Dr. Dwyer was asked whether someone with schizoaffective disorder
    would “be unable to understand right and wrong necessarily.” Id. at 899. In his
    estimation, “[i]t would depend on the nature of the symptoms at the time that we
    were talking about.” Id. at 899–900. As it did during its cross-examination of the
    defense’s witnesses, the government encouraged Dr. Dwyer to underscore how
    unlikely it was that Mr. Herriman was forced by the voices to make the bomb.
    See id. at 902 (“So [Mr. Herriman] indicated that he understood that these were
    voices . . . that were communicating with him?”).
    The government also used Dr. Dwyer to rebut the proposition—asserted by
    the psychologist who testified on behalf of the defense—that Mr. Herriman’s
    apparent attempt to spray-paint the bomb in order to sabotage it was reflective of
    delusional behavior. In Dr. Dwyer’s opinion, the spray-painting was possibly the
    product of delusional thoughts, “but not necessarily.” Id. at 906–07. The
    prosecutor then queried, following up on the same subject, “The desire to not
    want to hurt someone, is that delusional behavior?” Id. at 907. “Generally
    speaking, no,” Dr. Dwyer replied. Id. While Dr. Dwyer was on the stand, the
    government returned to the theme that Mr. Herriman was in possession of his
    faculties around the time of the alleged offense. In particular, Dr. Dwyer
    described Mr. Herriman’s inculpatory statements to a 911 operator as “coherent,
    22
    logical,” and indicative of an ability to “provide directions and make factual
    statements.” Id. at 908.
    In its closing argument, the government tied all of these various points
    together. It began by acknowledging that there was no question but that Mr.
    Herriman had a mental disease or defect. But it then turned to the factual matter
    of whether Mr. Herriman was in the throes of his mental disease at the time he
    made and planted the bomb. On that issue, the government disagreed strenuously
    with the theory put forth by the defense. The government’s perspective was
    illuminated as the prosecutor ran through each of the points he had made through
    his cross-examinations of the defense’s witnesses and through his direct
    examinations of the rebuttal witnesses: (1) Mr. Herriman could and would have
    sought help if he had needed it, and he did not do so; (2) Mr. Herriman was lucid
    and not in a manic state at the time of the incident; and (3) the voices did not
    provide any specifics on how to assemble the bomb.
    b
    To summarize, the defense averred at trial that Mr. Herriman was
    delusional and psychotic at the time he constructed and placed the bomb, whereas
    the government depicted him as someone who is sometimes psychotic and
    delusional but was not so while committing the crime of which he was accused.
    As such, there can be no serious contention that the parties were in agreement
    regarding the fact of Mr. Herriman’s mental condition at the time he made and
    23
    placed the bomb. And the nature of their factual disagreement was, at the very
    least, material to Mr. Herriman’s guilt of the charged offenses. Accordingly, on
    this record, we cannot discern how Mr. Herriman could qualify for a § 3E1.1
    downward adjustment. See, e.g., Melot, 732 F.3d at 1244 (deeming the granting
    of a § 3E1.1 adjustment clear error where the defendant “did not proceed to trial
    to preserve an issue unrelated to his factual guilt” (emphasis added)).
    To be sure, there was a legal dimension to the dispute over Mr. Herriman’s
    mental condition, in the sense that the parties were at odds over whether Mr.
    Herriman was sufficiently conscious or aware of the wrongfulness of his conduct
    to satisfy the legal criteria of an insanity defense. See R., Vol. I, at 120 (“For you
    to return a verdict of not guilty only by reason of insanity, the defendant must
    prove 1) that he suffered from a severe mental disease or defect when the crime
    was committed; and 2) that, as a result of this mental disease or defect, he was
    not able to understand what he was doing or to understand that it was wrong.”).
    However, that is not enough; our law demands more. Specifically, it demands a
    showing that the legal aspect of Mr. Herriman’s mental condition was the only
    dimension of his condition that he put at issue by going to trial. See McGehee,
    
    672 F.3d at 878
     (limiting post-trial § 3E1.1 reductions to defendants who insist on
    presenting their claims to a jury “only to ‘preserve issues that do not relate to
    factual guilt’” (emphasis added) (quoting U.S.S.G. § 3E1.1 cmt. n.2)). And this is
    where Mr. Herriman falls short.
    24
    We are not insensitive to the reality that it may not always be easy to tell
    when a challenge is purely legal—thereby making a defendant who advanced such
    a challenge at trial eligible for a § 3E1.1 adjustment—and when a challenge
    embodies a factual component, such that the defendant who pursued such a
    challenge at trial would be disqualified from receiving a § 3E1.1 adjustment.
    Nevertheless, wherever in this context the line between law and fact is, we have
    no doubt that Mr. Herriman’s claim falls cleanly on the wrong (i.e., factual) side
    of it. For, he and the government fiercely contested whether he was—as a factual
    matter—psychotic at the time he committed the charged acts. We are content to
    leave to our colleagues in the future—in cases that present closer questions—the
    task of sketching in greater detail the contours of this law-fact line.
    C
    In addition to his argument predicated on Gauvin, Mr. Herriman lodges a
    closely related claim that the factual findings underlying the district court’s
    decision to deny him the benefit of a § 3E1.1 adjustment were inadequate. Mr.
    Herriman believes that the defects in the district court’s findings have two
    ramifications: (1) we should accord no deference to the district court’s factual
    findings regarding the acceptance-of-responsibility issue; and (2) the absence of
    findings is itself a procedural error that calls for reversal. No matter how Mr.
    Herriman frames the argument or its implications, it is meritless.
    It is well-established that a district court has no obligation to “explain why
    25
    a particular adjustment [under the guidelines] is or is not appropriate.” United
    States v. Bowen, 
    437 F.3d 1009
    , 1019 (10th Cir. 2006) (alteration in original)
    (emphases added) (quoting United States v. Maldonado-Campos, 
    920 F.2d 714
    ,
    718 (10th Cir. 1990)) (internal quotation marks omitted). However, “when it is
    apparent from the court’s optional discussion that its factual finding may be based
    upon an incorrect legal standard, we must remand for reconsideration in light of
    the correct legal standard.” 
    Id.
     (emphasis added) (quoting Maldonado-Campos,
    
    920 F.2d at 718
    ) (internal quotation marks omitted).
    Recall that the district court explained its decision with the following
    remarks:
    One of the elements that the government was required to prove
    at trial was that the defendant committed the offenses knowingly
    and intentionally. By raising insanity as an affirmative defense,
    the defendant’s denial of his intentionality and knowingly
    committing the offenses directly challenges one of the elements
    of guilt. Therefore, the defendant is not eligible for reduction
    [for] acceptance of responsibility in this case.
    R., Vol. II, at 322–23.
    The only authority Mr. Herriman cites in support of his view that the
    district court’s stated rationale here was deficient is United States v. Montoan-
    Herrera, 
    351 F.3d 462
     (10th Cir. 2003). There, we remanded for resentencing
    because the district court, over the government’s objection, had granted a
    downward adjustment—that we assumed to be for acceptance of
    responsibility—without even acknowledging the specific Guidelines basis for the
    26
    adjustment. See 
    id. at 467
    . At bottom, we concluded that the district court
    committed reversible error because it did not even take the minimal step—in the
    face of the government’s objection—of identifying the particular conduct of the
    defendant that warranted the acceptance-of-responsibility adjustment. Compare
    
    id.
     (“The district court did not state what the adjustment was for nor did it make a
    finding that the requirements for the adjustment were satisfied.”), with 
    id.
     at 467
    n.6 (“In sentencing Herrera’s co-conspirators, the district court found that they
    were entitled to the acceptance of responsibility adjustment because they had
    provided an adequate factual basis for their guilty pleas. . . . We held that these
    were sufficient ‘findings’ because they were supported by the record.” (citations
    omitted)).
    In reaching this conclusion, we did not suggest that the court was obliged
    to go further and explain why the conduct found to be sufficient to support the
    Guidelines adjustment was in fact sufficient. Cf. 
    id. at 467
     (suggesting that in
    those cases where we did not require further findings, the requisite act had been
    done, in that “the district court specifically found defendant was entitled to an
    adjustment”). It should be obvious then that Montoan-Herrera offers Mr.
    Herriman no succor. Not only did the district court do what Montoan-Herrera
    required—identify the conduct of Mr. Herriman that disqualified him for the
    acceptance-of-responsibility downward adjustment—it went further and
    optionally explained why that conduct disqualified him for the reduction.
    27
    Thus, we can only reverse on this claim if “it is apparent from the court’s
    optional discussion that its factual finding may be based upon an incorrect legal
    standard.” Bowen, 
    437 F.3d at 1019
     (quoting Maldonado-Campos, 
    920 F.2d at 718
    ) (internal quotation marks omitted). We believe it is clear from our analysis
    in the preceding section that the district court’s rationale was grounded in the
    governing law. Accordingly, we discern no error here.
    III
    For the reasons explicated above, we AFFIRM Mr. Herriman’s sentence.
