PRISCILLA R. OWEN, Circuit Judge:
A jury convicted Paul Suarez for his involvement in a drug trafficking conspiracy and for firearms offenses. Suarez appeals contending that the convictions were not supported by sufficient evidence. He also asserts that the district court erred in imposing a 120-month (ten year) mandatory minimum prison sentence for possession of a sawed-off shotgun in furtherance of a drug trafficking crime. The evidence was sufficient to sustain each of Suarez’s convictions, and they are affirmed. But that the mandatory minimum sentence of 120 months of imprisonment was inapplicable, and we therefore vacate the sentence and remand to the district court for resentenc-ing.

After discovering methamphetamine in Timothy Sharp’s truck during the course of a traffic stop, Cooke County Police obtained a warrant to search the residence of Erica Gutierrez, from whom Sharp said he purchased the drugs. When police searched Gutierrez’s home, they found her and Paul Suarez—who, according to Sharp, acted as “consul or overseer” for Gutierrez’s drug deals—in the master bedroom. Also found in that room were a distributable amount of methamphetamine, baggies, scales, security cameras, a .380 caliber Davis pistol, shotgun shells, body armor, and a .20 gauge Winchester .sawed-off shotgun that, though disassembled, had ammunition in its chamber. Police also found a .20 gauge Ithaca sawed-off shotgun underneath a mattress in a second bedroom. During the search, officers answered a call to Gutierrez’s cell phone from Travis Puckett, who wanted t'o buy methamphetamine. Puckett agreed to meet at a local hotel, and he was arrested when he arrived there to consummate the transaction.
Gutierrez and Puckett were witnesses at Suarez’s trial. Gutierrez testified that Suarez distributed methamphetamine and split the profits with her, had stayed at the house the previous night, gave her the pistol, and knew about the Winchester but not the Ithaca. Puckett testified that Suar rez was often present when he bought methamphetamine from Gutierrez and that Suarez made the sale if Gutierrez was unavailable. Puckett also testified that the Ithaca, which he identified by the tape on its handle, was “always” in the master bedroom when he made purchases, there.
. Count-1 of the indictment charged Suarez with conspiracy to possess with intent to distribute narcotics in violation, of 21 U.S.C. § 846. Count II charged possession of the pistol and Winchester shotgun in furtherance of a drug trafficking offense in violation of 18 U.S.C. § 924(c). Counts III and IV alleged possession of the , unregistered Winchester and Ithaca shotguns in violation of 26 U.S.C. § 5861(d). Suarez moved for acquittal on Counts III and IV under Federal Rule of Criminal Procedure 29, but the district court denied the motion. The proposed jury charge and verdict form for Count II did not require the jury to specify which firearm—the pistol or the Winchester—supported guilt on Count II, and Suarez did not object at trial.
The jury found Suarez guilty on all four counts. The Presentence Investigation Report (PSR) recommended 60 months of imprisonment for Counts I, III, and IV and concluded that Count II required a ten-year minimum prison sentence, to run consecutively to any other counts. The district court adopted the recommendation and sentenced Suarez to 180 months of imprisonment, but stated on the record that it- would have sentenced Suarez to a shorter term but for the ten-year mandatory minimum sentence that it had concluded was applicable. This appeal followed.

The standard of review for insufficiency-of-the-evidence claims depends on whether the claims were preserved. We review claims preserved through a Rule 29 motion de novo, but “with substantial deference to the jury verdict.”1 We affirm “if a reasonable trier of fact could conclude ... the elements of the offense were established beyond a reasonable doubt.”2 Claims not preserved are. reviewed for plain error.3 Suarez must show a clear or obvious legal error that affects his substantial rights and “seriously affect[s] the fairness, integrity, or public reputation of the judicial proceedings.”4 In reviewing the sufficiency of the evidence, an error is “clear or obvious” “only if the record is ‘devoid of evidence pointing to guilt,’ or ... ‘the evidence on a key element of the offense [i]s so tenuous that a conviction would be shocking.’ ”5 Relief is appropriate under this exacting standard only if the Government’s evidence is “obviously insufficient”6 and the defendant shows “a manifest miscarriage of justice.”7 Under both standards, we “view[ ] the evidence in the light most favorable to the verdict and draw[] all reasonable'inferences from the evidence to support the verdict.”8
A
We- review the conviction under Count I for plain error.9 Count I charged Suarez with conspiracy to distribute, and possession with intent to distribute, 50 grams or .more of a mixture or substance containing a detectable amount of methamphetamine in violation of 21 U.S.C. §§ 841(a)(1) and 846. Defense counsel conceded that the evidence supported conviction under this count, and we agree that the evidence was sufficient.
To prove a drug conspiracy, the Government must prove, (1) an agreement between two or more persons to violate narcotics laws; (2)-knowledge of the agreement; and (3) voluntarily participation in the agreement.10 Gutierrez’s testimony alone provides sufficient evidence to establish all three elements. “A conviction, especially one accompanied by an accomplice instruction, may be sustained on the uncorroborated testimony of an accomplice so long as ‘the testimony is not incredible or otherwise insubstantial on its face.’ ”11 The district court gave the jury an accomplice instruction. Gutierrez testified that Suarez assisted her in selling methamphetamine and- divided the proceeds with her. Her testimony is neither incredible nor insubstantial on its face. .....
Gutierrez’s testimony was not the only evidence of Suarez’s involvement in the drug distribution conspiracy. Officers testified that they found Suarez in the master bedroom with Gutierrez and that the bedroom contained a distributable quantity of methamphetamine, packing and weighing materials, security cameras, guns, and body armor. Puckett testified that Suarez was usually present when he bought drugs from Gutierrez, Suarez had answered Gutierrez’s phone before, and Puckett went to the hotel where he was arrested because he assumed the male officer who answered Gutierrez’s phone was Suarez, Suarez argues that Gutierrez and Puckett .are unreliable' witnesses, but we generally “will not' disturb (the jury’s) verdict [or] weigh the-' credibility of witnesses.”12 The record is not “devoid of evidence pointing to guilt,” nor is the evidence “so tenuous that a conviction is shocking.”13
B
We also review the conviction on Count II for plain error. Count II charged Suarez with violating 18 U.S.C. § 924(c) by possessing firearms in furtherance of a drug trafficking crime. The firearms identified in Count II were the sawed-off Winchester .20 gauge shotgun and the Davis .380 caliber pistol.
To support a conviction for possession of a firearm in furtherance of a drug trafficking crime, the Government must prove that Suarez had either actual or constructive possession of a firearm14 and that the possession “further[ed], advance[d], or help[ed] forward” the drug .trafficking offense.15 The following non-exclusive factors are relevant to determining whether possession is “in furtherance” of a drug trafficking crime: (1) the type of drug activity conducted; (2) the accessibility of the firearm; (3) the type of firearm; (4) whether the firearm is stolen; (5) the legality of the possession; (6) whether the gun is loaded; (7) the proximity of the weapon to the drugs; and (8) the time and circumstances under which the firearm is found.16 “The mere presence of a firearm” is insufficient.17 When evidence of more than one firearm is presented to the jury to support a single count under 18 U.S.C. § 924(c)(1)(A), the jury is not required to agree unanimously on which weapon the defendant possessed.18
On plain error review, we conclude that the record is sufficient to sustain the conviction under § 924(c)(1)(A), and the consequent imposition of a five-year mandatory minimum sentence under § 924(c)(1)(A)®. The indictment alleged that “[o]n or about February 4, 2015,” the date that the search warrant was executed, Suarez possessed the Winchester shotgun and the Davis .380 caliber pistol in furtherance of a drug trafficking crime.
There is some question as to whether the Winchester shotgun could function as a firearm at the time it was found in the master bedroom. The shotgun was partially disassembled and was in three pieces. The stock was not connected and was lying on the floor under the bed. The portion of the shotgun that contained a shell was in a black bag under the mattress, and the top piece of the shotgun was along the bed rail. The testimony at trial was that in this disassembled' condition, the weapon could be fired but that it would not be safe to do so because “[t]here’s not a very good spot to hold onto the shotgun unless you’re holding near the breach.” There was “a possibility, a very distinct one” that “if you had made an attempt to fire that weapon, you probably would have injured yourself.” There was no evidence as to how quickly the Winchester could have been re-assembled. Nevertheless, we cannot say that “the record is ‘devoid of evidence pointing to guilt,’ or ... ‘the evidence on a key element of the offense [i]s so tenuous that a conviction would be shocking’ ”19 had the jury based its verdict on the Winchester shotgun.
In any event, both the Winchester and the pistol were in the same- room as, and accessible to, Suarez when the police found him, as were the drugs and distribution paraphernalia, surveillance equipment, and body armor. Gutierrez testified that Suarez knew about the Winchester and that he gave her the pistol. Suarez was an overnight guest at the house. Officer Benavides testified that Sharp identified Suarez as “consul” for Gutierrez and stated that Suarez would sit with a firearm during drug deals. Another officer testified that Suarez’s role as a “male overseer” to Gutierrez was typical in drug deals.
The jury was entitled to credit this evidence and testimony and find that Suarez actively assisted Gutierrez in her drug trafficking operations. There is support for the jury’s conclusion that Suarez possessed at least one of the two firearms found in the master bedroom and that such possession furthered the drug trafficking crimes.20
Suarez also challenges his conviction on Count II based on the failure of the district court to require that the jury unanimously determine which firearm formed the basis of the conviction. Because he did not object to the instruction at trial, we review for plain error.21 We have previously approved of the pattern jury instruction given at trial as a correct statement of the law.22 We have also held that the jury need not unanimously agree on which firearm supports the conviction for this offense.23 For purposes of a conviction under 18 U.S.C. § 924(c)(1)(A), whether a defendant used a particular firearm pertains to the means by which the crime was committed, and therefore a jury is not required to determine unanimously that a particular .firearm was used when an indictment charges that more-than one firearm was possessed.24 This is distinct from what is required to impose a statutory minimum sentence under § 924(c)(l)(B)(i), as we will discuss below.25 Possession of a particular type of firearm is an element of the offense for purposes of the statutory ten-year minimum sentence but not for a conviction of possession of a firearm in furtherance of drug trafficking crime.26 The district court therefore did not err in failing to instruct the jury to specify upon which firearm it based the conviction under § 924(c)(1)(A). While the jury instruction does not affect the validity of Suarez’s conviction, it does affect the validity of his sentence, as we consider in section III.
C
Because Suarez properly preserved his challenge to the verdicts on Counts III- and IV, we review the convictions on those counts de novo.27 On a sufficiency-of-the-evidence challenge, however, de novo review-permits us to evaluate only the reasonableness of the jury’s verdict, and not whether we believe that verdict was correct.28 Counts III and IV charged Suarez with possession of unregistered firearms—the- Winchester and the Ithaca—in violation of 26 U.S.C. § 5861(d). “[Possession may be actual or constructive.”29 Constructive possession is established when the evidence supports “a plausible inference that the defendant had knowledge of and access to the weapon or contraband.”30
Police found parts of the Winchester in plain sight and close proximity to Suarez, who was an overnight guest in the house.31 Gutierrez ancj Benavides testified that Suarez knew of the Winchester and sometimes carried a sawed-off shotgun during drug deals. The Government therefore met its burden to establish constructive possession.
The evidence is also sufficient to support the conviction as to Count IV, involving the Ithaca. Puckett testified that Suarez was usually at the house when Puckett purchased drugs and that the Ithaca shotgun was “always” by the dresser in the master bedroom. Though Gutierrez testified that neither she nor Suarez knew the Ithaca shotgun was in the house, a reasonable jury could have credited Puckett’s testimony over Gutierrez’s,32-Puckett’s testimony supports an inference of constructive possession.33

Congress has determined that if a person possessed .“a short-barreled rifle, short-barreled shotgun, or semiautomatic assault weapon,” in committing a crime defined in 18 .U.S.C. § 924(c), “the person shall be sentenced to a term of imprisonment of not less than 10 years.”34 Suarez challenges the district court’s imposition of a consecutive 120-month (ten-year) mandatory minimum sentence under § 924(c)(1)(B)© as to Count II. Because he failed to object to the imposition of this mandatory minimum sentence in the district court, we review for plain error.35 A sentencing error is plain if it is contrary to Supreme Court, or circuit precedent.36 The error affects substantial rights if “there is ‘a reasonable probability that, but for the error, [the defendant] would have received a lesser sentence.’”37 We may exercise our discretion to remand for resentencing if “the error ‘seriously affect[s] the fairness, integrity or public reputation of judicial proceedings,’ ”38 .The Government concedes plain error and,- in its brief, did not oppose remand. At oral argument, the Government affirmatively urged this court to remand • and to take into account- its concession of error.39 Though we must “give the issue independent review,”40 we conclude that remand is warranted/ • •
The district court’s imposition of. the ten-year mandatory minimum sentence was plain error. The Supreme Court determined in United. States v. O’Brien41 that, a court may not impose a thirty-year mandatory minimum under § 924(c)(l)(B)(ii), unless the jury determines beyond a reasonable doubt that the firearm at issue was a machine gun.42 Subsequently, in .Alleyne v. United States,43 the Supreme Court held .that any fact issue that, increases the. mandatory- minimum sentence must be submitted .-to a jury and found.beyond a reasonable doubt.'44 A mandatory minimum sentence of five years is generally required under 18 U.S.C. § 924(c)(1)(A)© for possession of a firearm in furtherance of a drug crime, but, as earlier noted, the minimum term of imprisonment increases to ten years if the firearm is a sawed-off shotgun.45 The Supíneme Court has held that jury unanimity is required in a federal criminal trial as to each element of a federal crime.46 Read together, the Supreme Court’s decisions make clear that the mandatory minimum ten-year sentence under § 924(c)(l)(B)(i) could not be imposed in the present case unless the factfinder at trial, which was a jury, unanimously found beyond a reasonable doubt that Suarez possessed a sawed-off shotgun in furtherance of a drug trafficking crime. The jury instruction did not require that the jury find which of the two firearms charged in Count II—the pistol or the sawed-off Winchester shotgun— formed the basis of its verdict. One or more jurors could have failed to find that the Winchester sawed-off shotgun was possessed in furtherance of drug trafficking. In light of Alleyne, the district court’s sentencing error was plain.47
This error affected Suarez’s substantial rights. Suarez received a sentence of imprisonment that the district court said it would not have imposed but for its conclusion that a mandatory minimum ten-year sentence under § 924( c) (1) (B) (i) was required. The district court’s statement establishes with reasonable probability that Suarez would have received a lesser sentence but for the court’s error.
The error seriously affects the fairness, integrity, and public reputation of the judicial process for a number of reasons. Principles found in Alleyne itself support this conclusion. The Court recognized in Al-leyne that “[ejlevating the low-end of a sentencing range heightens the loss of liberty associated with the crime: the defendant’s ‘expected punishment has increased as a result of the narrowed range’ and ‘the prosecution is empowered, by invoking the mandatory minimum, to require the judge to impose a higher punishment than he might wish.’ ”48 The Supreme Court reasoned that “[t]his reality demonstrates that the core crime and the fact triggering the mandatory minimum sentence together constitute a new, aggravated crime, each element of which must be submitted to the jury.”49 In this same vein, the Court observed that “[w]hen a finding of fact alters the legally prescribed punishment so as to aggravate it, the fact necessarily forms a constituent part of a new offense and must be submitted to the jury.”50 The error here is a Sixth Amendment violation, not solely a sentencing error. When a court fails to submit an issue to a jury, in violation of the Sixth Amendment, “the fairness, integrity, or'public reputation of judicial proceedings” is implicated, when, as here, the consequences for the defendant are an additional five years of imprisonment and the evidence that would have supported a jury’s finding on the omitted element is not “ ‘overwhelming’ or ‘essentially uncontroverted.’ ’•’51
The Court explained in Alleyne that the Sixth Amendment is violated because “[i]t is no answer to say that the defendant could have received the same sentence with or without that fact [that must be found by a jury].”52 That is because “[i]t is obvious, for example, that a defendant could not be convicted and sentenced for assault, if the jury only finds the facts for larceny, even if the punishments prescribed for each crime are identical. One reason is that each crime has different elements and a defendant can be convicted only if the jury has found each element of the crime of conviction.”53 The Court explained that an aggravating fact is “an element of a separate, aggravated offense that must be found by the jury, regardless of what sentence the defendant might have received if a different range had been applicable.” 54 “Indeed, if a judge were to find a fact that increased the statutory maximum sentence, such a finding would violate the Sixth Amendment, even if the defendant ultimately received a sentence falling within the original sentencing range (i.e., the range applicable without that aggravating fact).”55 In the present case, if we permitted the sentence to stand, Suarez would be imprisoned for an offense that a jury never found he committed. The district court said that it would not punish Suarez as it did but for the ten-year mandatory minimum sentence, which the district court erroneously thought applied. A Sixth Amendment violation seriously affects the fairness, integrity, and public reputation of the judicial process in this case because it results in the imposition of a sentence of an additional five years of imprisonment for a crime for which there was no conviction, and the evidence that might have supported a conviction under § 924(c)(l)(B)(i) is not strong.
This determination regarding the fourth prong of plain error review is consistent with prior decisions of this court, even absent a Sixth Amendment violation.56 Similarly, in United States v. John,57 we held that the fourth prong was met when the guidelines sentencing range was improperly calculated, and the sentence imposed exceeded the applicable range by 21 months of imprisonment.58 We based that determination on a number of considerations, including the fa'ct .that the sentence was reached without consideration of the correct range and because, were the sentence affirmed, it would be imposed without any findings-that ordinarily must accompany a sentence that is significantly above the guidelines range.59 We know in the case before us today that' the district court would not have imposed an additional five years of imprisonment had it known that the mandatory minimum ten-year sentence was inapplicable.. •
In a case involving monetary restitution, rather than liberty, this court vacated a sentence after applying the plain error standard of. review when the defendant was ordered to pay $164,988.98, and “without the error, the court could not have ordered restitution in an amount greater than $54,384.43.”60 Resentencing was similarly required after plain error review when the award ‘exceeded the permissible amount of restitution by $70,000.61 It is difficult, if not impossible, to place a monetary value on one’s liberty. But it is apparent that being subjected to five additional year? of imprisonment without any jury finding to authorize -that punishment is at least as offensive to notions of fairness as the imposition of restitution that is excessive by $70,000.
We may exercise our discretion to vacate a sentence imposed without the requisite finding by a jury62 if the evidence of the unproven factual predicate for a statutory minimum sentence enhancement is not “‘overwhelming’ and ‘essentially un-controverted.’”63 Here, the evidence regarding the Winchester shotgun is not overwhelming and essentially uncontro-verted.
IV
The dissenting opinion contends that we should not vacate the sentence or remand for resentencing, advancing several arguments. First, the dissenting opinion asserts that Suarez failed to address the fourth prong of plain error review in his briefing in our court.64 We disagree. There is no requirement that a defendant use the words “fourth prong” in order to raise sufficiently an issue that is subject to plain error review. Federal Rule of Appellate Procedure 28(a)(8)(A) requires that an appellant’s brief contain his or her “contentions and the reasons for them, with citations to the authorities and parts of the record on which the appellate relies.”.65 Under “a prudential construct that requires the exercise of discretion,” “[f]ailure to satisfy the requirements of Rule 28 .... ordinarily constitutes abandonment of the issue.”66 However, in exercising our discretion on this matter, “we must liberally construe briefs in determining what issues have been presented for appeal.”67
Suarez’s brief sufficiently presented his argument. His contentions regarding the ten-year mandatory minimum sentence are pertinent to his positions regarding both the Sixth Amendment violation and the sentence of imprisonment itself, both of which Suarez concedes in his brief are reviewed under the plain error standard. In contending that the district court plainly erred when it failed to require the jury to find which specific firearm formed the basis of the guilty verdict on Count II, Suarez explained that prior to trial, in the Notice of Penalty issued by the court, he was apprised that Count II carried a term of imprisonment of not less than 5 years. His brief also recounts that in his initial appearance, the magistrate judge admonished him that the minimum sentence for Count II was five years (not ten years) and that no mention was made of the ten-year minimum. He asserts in his brief that the failure of the court to require the jury to indicate which firearm, or firearms listed in the indictment was possessed in furtherance of a drug trafficking crime was not a “minor” omission because if the jury had “attributed the pistol to Mr. Suarez and not the disassembled Winchester shotgun, the mandatory minimum would have remained at five years instead of being increased to ten.” Suarez argues that the district court’s “hand was forced into sentencing Mr. Suarez to an enhanced [ten-year] minimum sentence that nobody was anticipating.” The brief then quotes .the district court’s statement.-that.it had'no discretion regarding the length of the sentence because of its conclusion that a. ten-year mandatory ■ minimum sentence applied. These are facts, not boilerplate assertions about the fourth prong of plain error, that .pertain to the gravity of the Sixth Amendment violation. and corresponding error in sentencing.
The very next section of Suarez’s brief, challenging the sentence of 180-months of imprisonment, reflects that Suarez filed a notice of no objections to the PSR, conceding that his sentencing arguments are subject to plain error review. The first subheading in this section of the brief asserts that “[b]y judicially fact-finding the enhancement increasing the mandatory minimum sentence from five year to ten years, the district court removed a required fact-question [sic] from the province of the jury.” This again reflects the argument that the Sixth Amendment violation and ten-yéar minimum, sentence are inextricably related. The brief then discusses Supreme .Court decisions which have held that any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and the brief asserts that “the finding that Suarez possessed the sawed-off shotgun in furtherance of drug-trafficking activity was a fact question to be decided by the jury,” He continues with further argument, including the assertion that his “sentence of 180 months was procedurally unreasonable because it was based upon a. judicial fact-finding of an issue that was required to be submitted to, and found by the jury. Appellant’s sentence was increased by five years due to an enhancement he had no notice of, and that was not proven to the requisite burden of proof. Therefore, this sentence should be vacated.” These facts coupled with citations to Supreme Court decisions regarding the Sixth Amendment’s requirements are more than adequate to support a conclusion that the Sixth Amendment error and consequent sentencing error seriously affects the fairness, integrity or public reputation of judicial proceedings.
None of the many decisions of our court cited by the dissenting opinion hold that in order to brief the fourth prong of plain error review adequately, the words “fairness, integrity or public reputation of judicial proceedings” must be used.68 To the contrary, the cases cited hold only that there must be a “showing” regarding the fourth prong.69 A “showing” regarding the fourth prong has been made by Suarez in his initial brief as to why the sentence imposed for a crime for which no jury convicted him must be vacated, if the principles sought to be embodied in the fourth prong have any réal meaning and power. This court evaluates substantive, not formulaic, arguments and rules accordingly. Suarez explained that his sentence is predicated on a crime that the jury never found was committed, the district court would not have imposed the sentence but for its error, and that his sentence of imprisonment was increased by five years. The fourth prong has not only been adequately briefed, but satisfied.
The dissenting opinion quotes this court’s unpublished decision in United States v. Monroe,70 in support of the proposition that “Suarez’s brief waives any claim to plain-error relief for the reasons we identified” in that case.71 The only error alleged on appeal in Monroe was “that the district court did not have a sufficient factual basis to accept his plea.”72 The defendant sought reversal of his conviction. His sentence was not at issue. This court held with regard to the third prong of the plain error standard of review, that Monroe had failed to show that his substantial rights were affected because he failed to “show a reasonable probability that, but for the error, he would not have entered the plea.”73 With regard to the fourth prong of plain error review, we explained that the defendant had “pointed to nothing beyond” the alleged failure to require presentation of a sufficient factual basis to accept Monroe’s guilty plea to establish that the error impugned the fairness, integrity or public reputation of the court system.74 We did not hold in Monroe that a defendant’s brief is inadequate unless it expressly recites the well-known elements of the fourth prong of plain error review.
Consistent with Monroe, Suarez has pointed to more than the Sixth Amendment error. He has “pointed to”75 facts. These include the fact that the district court stated that “if it werén’t for the mandatory mínimums, ! probably would go less than [120 months], but I don’t have that power.” He pointed to the fact that the result of the district court’s error was the imposition of a ten-year mandatory minimum sentence of imprisonment.
The circumstances of this case involve a “material and substantial” over-sentencing,76 a government concession of plain error, and facts that do not overwhelming support the conclusion that the disassembled Winchester was possessed in furtherance of drug trafficking at the time alleged. The fourth prong of plain error review is satisfied.
The dissenting opinion argues that the facts in this case do not “seriously call[] into question the integrity of our judicial system,” and that “[n]o one should reasonably think that the result here 'is unfair to this unobjecting defendant.”77 In determining on plain error review whether Sixth Amendment error seriously affects the fairness, integrity, or public reputation of judicial proceedings, courts should consider whether evidence of the element of the crime that was not submitted to the jury was “ ‘overwhelming’ and ‘essentially uncontroverted.’ ”78 As discussed above regarding the sufficiency of the evidence to support a conviction under Count II and the consequent five-year mandatory minimum sentence, we cannot say that there was no evidence to support a reasonable juror’s conclusion that Suarez possessed the Winchester, shotgun in furtherance of drug trafficking. But that evidence does not overwhelmingly establish that the disassembled Winchester was possessed in furtherance of drug trafficking at the time alleged in the indictment.
It is clear that Sixth Amendment error flowing from the failure to submit an element of a crime to a jury “may be forfeited ... by the failure to make timely assertion i of the right,” and that when a. jury “surely” would have found the missing element, a defendant should not be permitted to escape the more severe punishment prescribed by Congress.79 The Supreme Court made plain in Cotton that “[t]he real threat then to the ‘fairness, integrity, and public reputation of judicial proceedings’ would be if Respondents, despite the overwhelming and uncontrovert-ed evidence that they were involved in a vast drug conspiracy, were to receive á sentence prescribed for those committing less substantial ‘drug' offenses because of an error that was never objected to at trial.”80 But we cannot say, based on the facts of this case, that the jury “surely” would have found that Suarez possessed the Winchester shotgun in furtherance of drug trafficking at the time alleged in the indictment. We therefore exercise the discretion under the plain error standard of review to remand to the district court for resentencing.

Fox’ the foregoing reasons, Suarez’s conviction's on all counts are AFFIRMED. However, we VACATE the district court’s sentencing order as to' Count II and REMAND for resentencing. • ■
