Jаmes Andrew King pled guilty to being a felon in possession of a firearm, in violation of 18 U.S.C. § 922(g). The district court found that King had three previous convictions for violent felony offenses and was therefore subject to a minimum term of 180 months’ imprisonment under the Armed Career Criminal Act (ACCA). The court sentenced King to the statutory minimum. The question presented in this appeal is whether King’s adjudication of juvenile delinquency in 1995 qualifies as a conviction for a violent felony. Because we find that question cannot be answered without resorting to conjecture, we vacate King’s sentence and remand for resentencing.
I. BACKGROUND
The ACCA provides that a defendant who violates § 922(g) is subject to a mandatory minimum term of 180 months’ imprisonment if he has “three previous convictions ... for a violent felony.” 18 U.S.C. § 924(e)(1). A “previous conviction” for purposes of § 924(e)(1) “includes a finding that a person has committed an act of juvenile delinquenсy involving a violent felony.” § 924(e)(2)(C). The statute defines the term “violent felony” as
any crime punishable by imprisonment for a term exceeding one year, or any act of juvenile delinquency involving the use or carrying of a firearm, knife, or destructive device that would be punishable by imprisonment for such term if committed by an adult that—
(i) has as an element the use, attempted use, or threatened use of physical force against the person of another; or
(ii) is burglary, arson, or extortion, involves use of explosives, or otherwise involves conduct that presents a serious potential risk of physical injury to another....
§ 924(e)(2)(B). Under this definition, an act of juvenile delinquency involving the use or carrying of a firearm, knife, or destructive device may qualify as a violent felony, but only if the act of delinquency meets the other statutory criteria. Id.
King admits that he has two adult convictions for violent felony offenses. And King does not contest the fact that he was adjudicated a juvenile delinquent in 1995 for violating section 5-73-104 of the Arkansas Code, which at that time provided that
*1045 [a] person commits the offense of criminal use of prohibited weapons if ... he uses, possesses, makes, repairs, sells, or otherwise deals in any bomb, machine gun, sawed-off shotgun or rifle, firearm specially made or specially adapted for silent discharge, metal knuсkles, or other implement for the Infliction of serious physical injury or death which serves no common lawful purpose.
The disputed issue concerns the nature of the underlying act of juvenile delinquency; more precisely, which part of section 5-73-104 did King violate?
The Government produced two documents to prove the fact of King’s juvenile adjudication and the nature of the underlying act of delinquency: the delinquent conduct adjudicatiоn order (a fill-in-the-blanks form used by the county chancery court) and the predisposition report (a one-page report prepared by a juvenile intake officer). The adjudication order says that King was charged with “criminal use of a weapon,” in violation of section 5-73-104, but the order does not identify the weapon or the way that King allegedly used it. The label “criminal use of a weapon” is ambiguous; for while the title of section 5-73-104 is “criminal use of prohibited weapons,” the statute criminalizes using, possessing, making, repairing, selling, or otherwise dealing in prohibited weapons. Effectively, “criminal use” is defined to include simple possession of certain weapons and various other acts that might not constitute actual use of such weapons.
The predisposition report does not resolve the ambiguity regarding the weapons charge, though it does recite some of the relevant facts (“Andy” is the defendant):
On 4-9-95, 911 received a disturbance call that Andy was involved in. As the deputy was on his way to the call he saw Andy walking carrying a rifle. Statements were made to the officers that shots had been fired. Also, at one point Andy had a knife and was told to drop the knife, which he did. (These actions took place at the King’s home after the fight at [a] relative’s home.) Andy and his brother Tim had been fighting at his relative’s home, upsetting family members enough that they called 911 asking for help. The boys were physically fighting and calling each other names. 2
King conceded at sentencing that the predisposition report shows that he possessed a rifle. Nevertheless, King argued that his juvenile adjudication could not be counted as a conviction for a violent felony because neither the predisposition report nor the adjudication order establish that the riflе he possessed was sawed off (sawed-off rifles are prohibited under section 5-73-104, but the statute says nothing about typical full-length rifles).
The district court accepted the premise that the records of King’s juvenile adjudication do not conclusively establish that he possessed a sawed-off rifle. But the court suggested that it need not determine what weapon King was charged with “using” (i.e., using, possessing, making, repairing, selling, or otherwise dealing in) because the fact of King’s juvenile adjudication proved that King possessed either a sawed-off rifle or some “other implement for the infliction of serious physical injury or death which serves no common lawful purpose.” As the court put it,
to be legitimately convicted under the statute [section 5-73-104], he would have to be in possession of a sawed-off rifle, or, you know, I mean, that’s the way it’s charged, “or other implement for the infliction of serious physicаl injury or death which serves no common lawful purpose.” The knife is not de *1046 scribed, but the knife could meet that definition, depending on what it was. I mean, an ordinary pocketknife has lots of lawful purposes, but there may be some kinds of knives that have no purpose other than inflicting injury on a human being. But he was convicted of possessing one of these kinds of implements, that has no purpose other than infliction of physical injury or death and which can serve no common lawful purpose.
The court went on to find that this case “is directly on point with
Vincent,”
referring to a decision in which we held that the defendant’s previous conviction under section 5-73-104 was for a violent felony.
United States v. Vincent (Vincent I),
II. DISCUSSION
As we said at the outset, the question presented in this appeal is whether King’s adjudication of juvenile delinquency in 1995 qualifies as a conviction for a violent felony. We begin our analysis by winnowing that general question down to more manageable size. We can state with confidence that the underlying act of juvenile delinquency satisfies one of the criteria for classification as a violent felony, since it would be punishable by imprisonment for more than one year if committed by an adult. See 18 U.S.C. § 924(e)(2)(B); Ark.Code Ann. §§ 5-73-104(c) (1995) (providing that a violation of the statute is at least a Class D felony), 5-4-401(a)(5) (1995) (providing that the maximum sentence for a Class D felony is six years’ imprisonment). And King has never challenged the notion that his act of juvenile delinquency involved the use or carrying of a firearm or knife, so we will assume for purposes of this appeal that the use-or-carry provision of § 924(e)(2)(B) is satisfied as well. The Government does not argue that the underlying act of juvenile delinquency “has as an element the use, attempted use, or threatened use of physical force against the person of another.” § 924(e)(2)(B)(i). Nor does the Government argue that the act of juvenile delinquency “is burglary, arson, or extortion, [or] involves use of explosives.” § 924(e)(2)(B)(ii). The dispositive question thus becomes whether King’s juvenile adjudication was for an act of delinquency that “otherwise involves conduct thаt presents a serious potential risk of physical injury to another.” Id.
After
Begay v. United States,
To decide whether an adult сonviction meets the two-part test set out in
Begay,
courts must apply the “categorical approach” adopted by the Supreme Court in
Taylor v. United States,
The Supreme Court has said that “[the] categorical approach requires courts to choose the right category. And sometimes the choice is not obvious.”
Chambers v. United States,
555 U.S. -,
We hold that the district court misapplied the categorical approach by failing to “choose the right category” in which to place the underlying act of juvenile delinquency; indeed, the court failed to choose a category at all. On the present record, we cannot determine in the first instance
*1048
whether King’s juvenile adjudication involved possеssing a sawed-off rifle as opposed to possessing some “other implement,” such as a knife. If we put the Government’s proof in its best light, the most we can say is that King was likely charged with possession of a prohibited weapon.

Although the narrative in the predisposition report indicates that King possessed a rifle and a knife, it does not identify which weapon King was charged with possessing. In the end, we cannot choose one of thesе categories without resorting to conjecture. Thus, we cannot affirm King’s sentence, for it should go without saying that a sentence enhancement may not be applied on the basis of guesswork.
See United States v. Chambers,
The Government suggested at sentencing that the uncertainty concerning the underlying act of juvenile delinquency did not matter because this court had held that any conviction under section 5-73-104 “necessarily is going to be a crime of violence [i. e., violent felony] as 924(e) would define it.” The district court adopted the Government’s suggestion, finding that our decision in Vincent I was controlling. The Government’s and the district court’s interpretation of Vincent I was too broad.
To be sure, we held in
Vincent I
that the defendant’s previous conviction under section 5-73-104 was for a violent felony.
In any event, after King had been sentenced, the Supreme Court granted Vincent’s petition for a writ of certiorari, vacated our decision in
Vincent I,
and remanded for further consideration in light of
Begay
and
Chambers. Vincent v. United States,
555 U.S. -,
We acknowledge that
Vincent II
sometimes refers to “possession of a dangerous weapon” rather than “possession of a sawed-off shotgun.”
See
At present, we decline to decide in the abstract whether the crime of possеssing a generic “implement for the infliction of serious physical injury or death which serves no common lawful purpose” (or a knife with those characteristics) qualifies as a violent felony under the ACCA’s “otherwise” clause. The Government did not brief that question because it simply assumed that Vincent II was controlling. In the absence of a threshold finding about the underlying act of juvenile delinquency, addressing all of the various ways that King might have violated section 5-73-104 would be unwise; in fact, it would almost certainly produce a partially advisory opin *1050 ion. Accordingly, we remand to the district court for further proceedings consistent with our description of the categorical approach and our explanation of the holding in Vincent II. 6
We do not impose any limitations on the evidence that the district court may consider on remand, so the court “can hear any relevant evidence ... that it could have heard at the first hearing,”
United States v. Dunlap,
Finally, we wish to make clear that nothing in this opinion should be read as casting doubt on the validity of King’s juvenile adjudication. To the extent King makes a collateral attack on the validity of the 1995 adjudication, we summarily reject his argument.
See Daniels v. United States,
*1051 III. CONCLUSION
For the foregoing reasons, we vacate King’s sentence and remand for resentencing.
Notes
. We have normalized the capitalization and corrected obvious punctuation errors.
. Throughout this opinion, we use the ACCA term "act of juvenile delinquency” in a generic sense, analogous to how we use the terms “offense” or “crime” when applying thе categorical approach in cases involving contested adult convictions.
See Begay,
. Again, we are assuming for purposes of this appeal that King's juvenile adjudication satisfies the use-or-carry provision of § 924(e)(2)(B), even though that requirement apparently was overlooked by the parties and the district court. Indeed, the Government's position at sentencing and on appeal appears to be that King was chargеd with simple possession of a prohibited weapon. See Government's Br. at 6 ("[T]hough King argues that he was not in possession of a sawed-off rifle, his conviction serves as conclusive proof that he possessed a weapon which could have inflicted serious physical injury or death on another.” (emphasis added)); id. at 14 ("King's [juvenile] conviction conclusively establishes that he was in possession of a weapon which had the capacity to inflict serious physical injury or death....” (emphasis added)). Obviously, a person can possess a weapon without using or carrying it, but we are willing to assume that the underlying act of juvenile delinquency in this case involved carrying a firearm or knife rather than possession simpliciter. We will go no further than that, however, since the Government has not proved that King was charged with using a weapon, in the sense of actual use (e.g., brandishing or firing the weapon). For the sake of concision, we will continue to refer to the сrime of "possessing” a weapon rather than “possessing by carrying.”
. We noted in
Vincent II
that "the Arkansas Supreme Court has held that a conviction for use of each prohibited weapon listed in [section 5-73-104] — including a sawed-off shotgun — has the element that the weapon 'will inflict serious physical injury or death
and
serves no lawful purpose.’ ”
. If it is possible to determine on remand that King’s juvenile adjudication involved possessing a sawed-off rifle, then
Vincent II
will control, even though
Vincent II
addressed the crime of possessing a sawed-off shotgun. In our view, the crimes of possessing a sawed-off shotgun and possessing a sawed-off rifle "amount to variations on a single theme,” so the district court may "consider them as together constituting a single category.”
