Justice KAGAN took no part in the consideration or decision of these cases.

As one of several measures to punish gun possession by persons engaged in crime, Congress made it a discrete offense to use, carry, or possess a deadly weapon in connection with "any crime of violence or drug trafficking crime." 18 U.S.C. § 924(c)(1). The minimum prison term for the offense described in § 924(c) is five years, § 924(c)(1)(A)(i), in addition to "any other term of imprisonment imposed on the [offender]," § 924(c)(1)(D)(ii). The two consolidated cases before us call for interpretation of § 924(c) as that provision was reformulated in 1998.

Kevin Abbott and Carlos Rashad Gould, petitioners here, defendants below, were charged with multiple drug and firearm offenses; charges on which they were convicted included violation of § 924(c). Each objected to the imposition of any additional prison time for his § 924(c) conviction. Their objections rested on the "except" clause now prefacing § 924(c)(1)(A). Under that clause, a minimum term of five years shall be imposed as a consecutive sentence "[e]xcept to the extent that a greater minimum sentence is otherwise provided by [§ 924(c) itself] or by any other provision of law."

Abbott and Gould read § 924(c)'s "except" clause to secure them against prison time for their § 924(c) convictions. They claim exemption from punishment under § 924(c) because they were sentenced to greater mandatory minimum prison terms for convictions on other counts charging different offenses. The "except" clause, they urge, ensures that § 924(c) offenders will serve at least five years in prison. If conviction on a different count yields a mandatory sentence exceeding five years, they maintain, the statutory requirement is satisfied and the penalty specified for the § 924(c) violation becomes inoperative.

The courts below, agreeing with the Government's construction of the statute, read § 924(c)(1) as independently requiring a sentence of at least five years, tacked onto any other sentence the defendant receives. The "except" clause refers to "a greater minimum sentence ... otherwise provided." "[O]therwise provided" for what, the courts below asked; their answer, for conduct offending § 924(c), i.e., possessing a firearm in connection with a crime of violence or drug-trafficking crime.

A defendant is not spared from a separate, consecutive sentence for a § 924(c) conviction, the lower courts determined, whenever he faces a higher mandatory minimum for a different count of conviction. Instead, according to the courts below and the Government here, the "except" clause applies only when another provision—whether contained within or placed outside § 924(c)—commands a longer term for conduct violating § 924(c). For example, the mandatory minimum sentence for a § 924(c) offense is five years, but if the firearm is brandished, the minimum rises to seven years, and if the firearm is discharged, to ten years. § 924(c)(1)(A)(i), (ii), (iii). A defendant who possessed, brandished, and discharged a firearm in violation of § 924(c) would thus face a mandatory minimum term of ten years.

We hold, in accord with the courts below, and in line with the majority of the Courts of Appeals, that a defendant is subject to a mandatory, consecutive sentence for a § 924(c) conviction, and is not spared from that sentence by virtue of receiving a higher mandatory minimum on a different count of conviction. Under the "except" clause as we comprehend it, a § 924(c) offender is not subject to stacked sentences for violating § 924(c). If he possessed, brandished, and discharged a gun, the mandatory penalty would be 10 years, not 22. He is, however, subject to the highest mandatory minimum specified for his conduct in § 924(c), unless another provision of law directed to conduct proscribed by § 924(c) imposes an even greater mandatory minimum.

Abbott and Gould, defendants in unrelated prosecutions, were each charged with violating § 924(c)(1)(A)(i) by possessing a firearm in furtherance of a drug-trafficking crime. Abbott's case was tried to a jury in the Eastern District of Pennsylvania, which convicted him on the § 924(c) count and three others: two predicate trafficking counts, 21 U.S.C. §§ 841, 846, and being a felon in possession of a firearm, 18 U.S.C. § 922(g). Given Abbott's extensive criminal history, his felon-in-possession conviction triggered a 15-year mandatory minimum under the Armed Career Criminal Act (ACCA), 18 U.S.C. § 924(e). The District Court sentenced Abbott to the 15 years mandated by ACCA, and to an additional five years for the § 924(c) violation, yielding a total prison term of 20 years.1

Gould's indictment listed seven separate drug and firearm charges. In return for Gould's agreement to plead guilty, the Government dropped all but two: one § 924(c) offense and one predicate drug-trafficking crime. The latter, for conspiracy to possess with intent to distribute cocaine base, carried a ten-year mandatory minimum under § 841(b)(1)(A). Firearm involvement was not an element of that offense. The United States District Court for the Northern District of Texas imposed a sentence of 11 years and 5 months for the trafficking offense and an additional five years for the § 924(c) violation, for a total of 16 years and 5 months.

On appeal, Abbott and Gould challenged the five-year consecutive sentence each received under § 924(c). Abbott urged that ACCA's 15-year mandatory minimum triggered § 924(c)'s "except" clause, because ACCA qualified as "[an]other provision of law" that "provided" a "greater minimum sentence." Gould said the same of the ten years commanded by his predicate trafficking crime.

The United States Court of Appeals for the Third Circuit affirmed Abbott's sentence, concluding that the "except" clause "refers only to other minimum sentences that may be imposed for violations of § 924(c)." United States v. Abbott, 574 F.3d 203, 208 (2009). Gould fared no better before the Fifth Circuit. United States v. Gould, 329 Fed.Appx. 569, 570 (2009) (per curiam). That court's precedent already confined the exception to conduct offending § 924(c). United States v. London, 568 F.3d 553, 564 (2009). To resolve the division among the Circuits on the proper construction of § 924(c)'s "except" clause,2 we granted certiorari in both cases and consolidated them for argument. 559 U.S. ___, 130 S.Ct. 1283, 1284, ___ L.Ed.2d ___ (2010).

A

Congress enacted 18 U.S.C. § 924(c) as part of the Gun Control Act of 1968, 82 Stat. 1213. The "except" clause, which did not appear in § 924(c) as originally composed, was introduced by statutory amendment in 1998. See An Act [t]o throttle criminal use of guns, 112 Stat. 3469. We begin by setting out § 924(c), first as it read before 1998, then as amended that year.

The earlier version read in relevant part:

If this pre-1998 text governed, all agree, separate counts of conviction would have no preemptive force, and Abbott and Gould would have been correctly sentenced under § 924(c). The question we confront is whether Congress' 1998 reformulation of § 924(c) rendered the sentences imposed on Abbott and Gould excessive.

The 1998 alteration responded primarily to our decision in Bailey v. United States, 516 U.S. 137, 116 S.Ct. 501, 133 L.Ed.2d 472 (1995). In proscribing "use" of a firearm, Bailey held, § 924(c)(1) did not reach "mere possession" of the weapon. Id., at 144, 116 S.Ct. 501. Congress legislated a different result; in the 1998 revision, "colloquially known as the Bailey Fix Act," the Legislature brought possession within the statute's compass. United States v. O'Brien, 560 U.S. ___, ___, 130 S.Ct., at 2179 (2010) (internal quotation marks omitted).

In addition to the change prompted by Bailey, Congress increased the severity of § 924(c) sentences in two other respects: The 1998 revision "changed what were once mandatory sentences into mandatory minimum sentences," O'Brien, 560 U.S., at ___, 130 S.Ct., at 2179 ; and it elevated the sentences for brandishing and discharging a firearm and for repeat offenses. Congress also restructured the provision, "divid[ing] what was once a lengthy principal sentence into separate subparagraphs." Id., at ___, 130 S.Ct., at 2176. And it added the prefatory "except" clause at issue in the cases now before us. As amended, § 924(c)(1)(A) prescribes:

The 1998 reformulation, furthermore, removed to separate paragraphs the provisions commanding higher penalties for especially destructive weapons and "second or subsequent" offenses. See § 924(c)(1)(B), (C).3 While leaving the penalties for highly destructive weapons unchanged, the revision raised the base punishment for "second or subsequent" offenses from 20 years to 25. Ibid. The reformulation also transferred the bar on concurrent sentences to § 924(c)(1)(D)(ii):

B

The leading portion of the "except" clause, which now prefaces § 924(c)(1)(A), refers to a "greater minimum sentence ... otherwise provided by this subsection," i.e., by § 924(c) itself; the second segment of the clause refers to a greater minimum provided outside § 924(c) "by any other provision of law." Beyond debate, the latter instruction does not relieve a § 924(c) offender of additional punishment "simply because a higher mandatory minimum sentence exists in the United States Code." Brief for Petitioner in No. 09-479, p. 19 (hereinafter Abbott Brief). Were it otherwise, the statute's ascending series of minimums, set out in § 924(c)(1)(A)-(C), would have no work to do; the only possible § 924(c) sentence would be the Code's highest—life. The "except" clause, it is therefore undisputed, "has to have some understood referent to be intelligible." United States v. Parker, 549 F.3d 5, 11 (C.A.1 2008). What should that referent be? As we comprehend the clause, to determine whether a greater minimum sentence is "otherwise provided ... by any other provision of law," the key question one must ask is: otherwise provided for what? As earlier noted, see supra, at 23, most courts, in line with the courts below and the Government, have answered: for the conduct § 924(c) proscribes, i.e., possessing a firearm in connection with a predicate crime.

Abbott and Gould disagree and offer diverse readings. Gould principally would apply the "except" clause to preclude a § 924(c) sentence whenever "any of a defendant's counts of convictio[n] at sentencing" require a greater minimum sentence. Brief for Petitioner in No. 09-7073, p. 14 (hereinafter Gould Brief).

In lieu of Gould's position that any greater minimum sentence on a different count of conviction will do, Abbott advances a somewhat narrower "transactional approach." Any sentence imposed on the defendant fits the bill, he urges, so long as the sentence was imposed "because of the criminal transaction that triggered § 924(c) in the first place." Abbott Brief 10. Accord United States v. Williams, 558 F.3d 166, 171 (C.A.2 2009).

Abbott also tenders an alternative construction: The minimum sentence "otherwise provided" must be for a firearm offense—for example, Abbott's felon-in-possession charge—involving the same firearm that triggered § 924(c).4 Conceding that this reading is "not commanded by the [statute's] plain language," Tr. of Oral Arg. 24, Abbott asserts that it advances § 924(c)'s goal—to discourage bearing arms in furtherance of crime—while avoiding the imposition of "two consecutive mandatory minimum sentences for the single use of a single firearm," Abbott Brief 47 (emphasis omitted).

The three interpretations just described share a common premise. In adding the "except" clause in 1998, all three posit, Congress adopted a less aggressive mode of applying § 924(c), one that significantly reduced the severity of the provision's impact on defendants. Like the courts below, we regard this premise as implausible. As earlier observed, see supra, at 24-26, the pre-1998 version of § 924(c) prescribed a discrete sentence—punishment to be imposed regardless of the sentence received for the predicate crime or any separate firearm conviction. Abbott and Gould think the "except" clause installed, instead, a modest scheme designed simply to ensure that all § 924(c) offenders "serve at least 5 years in prison." Gould Brief 5; see Abbott Brief 10. We doubt that Congress meant a prefatory clause, added in a bill dubbed "An Act [t]o throttle criminal use of guns," to effect a departure so great from § 924(c)'s longstanding thrust, i.e., its insistence that sentencing judges impose additional punishment for § 924(c) violations.

Were we to accept any of the readings proposed by Abbott or Gould, it bears emphasis, we would undercut that same bill's primary objective: to expand § 924(c)'s coverage to reach firearm possession. In 1999, more than half of those who violated § 924(c) in connection with a drug-trafficking offense received a mandatory minimum of ten years or more for that trafficking offense. Letter from Glenn R. Schmitt, United States Sentencing Commission, to Supreme Court Library (Nov. 10, 2010) (available in Clerk of Court's case file). Congress, however, imposed only a five-year minimum for firearm possession "in furtherance of" a drug offense. As construed by Abbott and Gould, the amendment to include firearm possession as a § 924(c) offense would spare the most serious drug offenders from any discrete punishment for the very firearm activity the amendment targeted. "We are disinclined to say that what Congress imposed with one hand ... it withdrew with the other...." Logan v. United States, 552 U.S. 23, 35, 128 S.Ct. 475, 169 L.Ed.2d 432 (2007).

Abbott's and Gould's proposed readings, moreover, would result in sentencing anomalies Congress surely did not intend. We note first that § 924(c), as they construe it, would often impose no penalty at all for the conduct that provision makes independently criminal. Tr. of Oral Arg. 52. For example, an individual who sold enough drugs to receive a ten-year minimum sentence under § 841(b)(1)(A) could, so far as § 924(c) is concerned, possess or even brandish a gun without incurring any additional punishment.

Stranger still, under the Abbott and Gould readings, the worst offenders would often secure the shortest sentences. Consider two defendants convicted of trafficking in cocaine. The first possesses 500 grams and is subject to a mandatory minimum of five years, § 841(b)(1)(B); the second possesses five kilograms and is subject to a mandatory minimum of ten years, § 841(b)(1)(A). Both brandish firearms, calling for a sentence of seven years under § 924(c)(1)(A)(ii). The first defendant, under all readings, will spend at least 12 years in prison. The second defendant's ten-year drug minimum, according to Abbott and Gould, triggers the "except" clause and wipes out that defendant's § 924(c) penalty; though the more culpable of the two, the second defendant's minimum term would be just ten years. Brief for United States 40. Like the Third Circuit below, "[w]e are confident that Congress did not intend such a bizarre result." 574 F.3d, at 209.

Abbott's alternative construction, which homes in on other firearm offenses, gives rise to similar oddities. On this reading, Abbott's 15-year ACCA sentence for being a felon-in-possession would preempt his five-year § 924(c) sentence, and his minimum term would be 15 years, rather than 20.5 But if ACCA were not at issue, Abbott's minimum term would be the same 15 years: his five-year § 924(c) sentence on top of his ten-year drug sentence. Qualification as a career criminal would carry no consequence.

Nor does Abbott's second construction necessarily promote more equitable outcomes. Suppose, for example, that a career criminal sold drugs together with a first-time offender, and both brandished firearms in the process. The first-time offender, lacking a felon-in-possession conviction, would serve a seven-year § 924(c) sentence on top of a ten-year drug sentence, for a total of 17 years. But the career criminal's ACCA sentence would preempt the § 924(c) sentence; he would serve only 15 years.

Abbott and Gould respond that sentencing judges may take account of such anomalies and order appropriate adjustments. We observe first that no correction or avoidance appears possible for the anomaly that, while § 924(c) "defines a standalone crime," a § 924(c) sentence would be wiped out by a wholly separate and independent conviction. United States v. Easter, 553 F.3d 519, 526 (C.A.7 2009) (per curiam) ("A determination of guilt that yields no sentence is not a judgment of conviction at all."). We do, however, agree that a judge exercising discretion under 18 U.S.C. § 3553(a) "would [not] be required to sentence" a more culpable defendant to a lesser term; the judge could increase that defendant's sentence for a predicate crime to make up for § 924(c)'s failure to effect any enlargement of the time served. United States v. Whitley, 529 F.3d 150, 155 (C.A.2 2008). But we doubt Congress had such a cure in mind in 1998, seven years before we held, in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), that district courts have discretion to depart from the Sentencing Guidelines on the basis of § 3553(a).

Abbott and Gould alternatively contend that Congress could have anticipated that the then-mandatory Guidelines would resolve disparities. See Abbott Brief 32-35; Gould Brief 30-32. On this view, the "except" clause ensures that a § 924(c) offender incurs a minimum sentence of considerable length; the Guidelines would then control, elevating that sentence based on firearm possession or use. See United States Sentencing Commission, Guidelines Manual §§ 2D1.1(b)(1), 2K2.1(b)(5) (Nov. 1998) (increasing offense level for defendants who use or possess firearms in course of violent crime or drug trafficking); §§ 2D1.1(b)(1), 2K2.1(b)(6) (Nov. 2009) (same).

We do not gainsay that Abbott and Gould project a rational, less harsh, mode of sentencing. But we do not think it was the mode Congress ordered. Congress expressly rejected an analogous scheme in 1984, when it amended § 924(c) in the same law that created the Sentencing Commission and the Guidelines. Pub.L. 98-473, 98 Stat. 1987, 2138. Four years earlier, in Busic v. United States, 446 U.S. 398, 404, 100 S.Ct. 1747, 64 L.Ed.2d 381 (1980), we had read § 924(c) to impose no penalty when the predicate crime itself prescribed a firearm enhancement; similarly, Abbott and Gould now read § 924(c) to impose no penalty when the Guidelines prescribe a firearm enhancement to the predicate sentence. The 1984 legislation "repudiated" Busic, clarifying that § 924(c) applied even when the predicate crime already "provides for an enhanced punishment if committed by the use of a deadly or dangerous weapon or device." United States v. Gonzales, 520 U.S. 1, 10, 117 S.Ct. 1032, 137 L.Ed.2d 132 (1997) (internal quotation marks omitted).

Between 1984 and 1998, Congress expanded the reach or increased the severity of § 924(c) on four occasions, never suggesting that a Guidelines firearm enhancement might suffice to accomplish § 924(c)'s objective.6 Nor is there the slightest indication that Congress was contemplating the Guidelines' relationship to § 924(c) when it added the "except" clause in the 1998 amendments.7

The "except" clause, we note, would have been a most haphazard way to achieve a Guidelines-driven rollback of § 924(c). If Congress wanted to ensure that § 924(c) offenders "receive at least five years in prison," and to rely on the Guidelines for the rest, Abbott Brief 10, there was an obvious solution: Congress could have excised all prescriptions ordering that § 924(c) sentences shall run consecutively to other sentences. Without such a requirement, all defendants would benefit from a minimum-plus-Guidelines regime—not just the most culpable offenders. Congress did not adopt that obvious solution, we think, because it did not want the Guidelines to supplant § 924(c).

C

The Government's reading of the "except" clause, we are convinced, makes far more sense than the interpretations urged by Abbott and Gould. In imposing a sentence for a § 924(c) violation "[e]xcept to the extent that a greater minimum sentence is otherwise provided ... by any other provision of law," Congress meant:

This reading gives effect to the statutory language commanding that all § 924(c) offenders shall receive additional punishment for their violation of that provision, a command reiterated three times. First, the statute states that the punishment specified in § 924(c)(1) "shall" be imposed "in addition to" the penalty for the predicate offense. § 924(c)(1)(A). Second, after Busic, § 924(c) demands a discrete punishment even if the predicate crime itself "provides for an enhanced punishment if committed by the use of a deadly or dangerous weapon or device." Ibid. Third, § 924(c)(1)(D)(ii) rules out the possibility that a § 924(c) sentence might "run concurrently with any other term of imprisonment." We doubt that Congress, having retained this thrice-repeated instruction, would simultaneously provide an exception severely limiting application of the instruction. Cf. Greenlaw v. United States, 554 U.S. 237, 251, 128 S.Ct. 2559, 171 L.Ed.2d 399 (2008) ("We resist attributing to Congress an intention to render a statute so internally inconsistent.").

Interpreting the "except" clause to train on conduct offending § 924(c) also makes sense as a matter of syntax. The "except" clause is not a standalone enactment, or even a standalone sentence. Rather, it precedes and qualifies § 924(c)(1)(A)'s principal clause, which punishes the possession of a firearm in connection with specified predicate crimes. The "grammatical and logical scope" of a proviso, we have held, "is confined to the subject-matter of the principal clause" to which it is attached. United States v. Morrow, 266 U.S. 531, 534-535, 45 S.Ct. 173, 69 S.Ct. 425 (1925). As a proviso attached to § 924(c), the "except" clause is most naturally read to refer to the conduct § 924(c) proscribes. Accord United States v. Villa, 589 F.3d 1334, 1343 (C.A.10 2009).

There is strong contextual support for our view that Congress intended the "except" clause to serve simply as a clarification of § 924(c), not as a major restraint on the statute's operation. At the same time Congress added the "except" clause, it made the rest of § 924(c) more complex. The 1998 revision divided the statute's existing sentencing prescriptions into four paragraphs in lieu of one, and added new penalties for brandishing and discharging a firearm. § 924(c)(1)(A)-(D). We know that Congress thought the restructuring might confuse sentencing judges: Warding off confusion, all agree, was the Legislature's sole objective in adding the initial part of the "except" clause, which covers greater minimums provided "by this subsection." That portion of the clause instructs judges to pick the single highest sentence stipulated for a § 924(c) violation within § 924(c) itself, and not to stack ten years for discharging a gun on top of seven for brandishing the same weapon, whenever a defendant does both.

In referencing greater minimums provided by "any other provision of law," we think, the second portion of the "except" clause simply furnishes the same no-stacking instruction for cases in which § 924(c) and a different statute both punish conduct offending § 924(c). Congress likely anticipated such cases when the "except" clause was framed in 1998, for the bill that reformulated the text of § 924(c) did just one thing more: It amended 18 U.S.C. § 3559(c) to command a life sentence when certain repeat felons are convicted of "firearms possession (as described in § 924(c))." Pub.L. 105-386, § 1(b), 112 Stat. 3470.

Our interpretation, Abbott and Gould protest, renders the second part of the "except" clause effectively meaningless. Section 3559(c) is the only existing statute, outside of § 924(c) itself, the Government places within the "except" clause. Tr. of Oral Arg. 32-35, 42-44.8 But § 3559(c) already imposes a life sentence. A defendant would find little comfort in knowing that no § 924(c) sentence, say five years or seven, will be tacked on to his § 3559(c) life term.

As Courts of Appeals have observed, however, the "any other provision of law" portion of the "except" clause installs a "safety valve." United States v. Studifin, 240 F.3d 415, 423 (C.A.4 2001). It "allow[s] for additional § 924(c) sentences," akin to the sentence prescribed in § 3559(c), that Congress may codify outside § 924(c) "in the future." See Abbott, 574 F.3d, at 208. We do not regard this allowance as "implausible." See Abbott Brief 22; Gould Brief 21. As the Government points out, "there is nothing unusual about Congress prescribing mandatory minimum penalties for substantive offenses codified in other provisions." Brief for United States 22. See, e.g., § 3559(c) (prescribing penalties for violations of, inter alia, 49 U.S.C. § 46502 and 18 U.S.C. §§ 1111, 2111, 2113, and 2118); § 3559(d) (prescribing penalties for violations of, inter alia, 18 U.S.C. §§ 2422, 2423, and 2251); 18 U.S.C. § 924(e) (prescribing penalty for violation of § 922(g)). See also 18 U.S.C. § 924(j)(1) (prescribing a nonmandatory penalty of death for individuals who commit murder with a firearm in the course of a § 924(c) offense).

Our decisions in Gonzales and Republic of Iraq v. Beaty, 556 U.S. ___, 129 S.Ct. 2183 (2009), do not warrant a different conclusion. We observed in Gonzales that "the word `any' [ordinarily] has an expansive meaning." 520 U.S., at 5, 117 S.Ct. 1032 (holding that "any other term of imprisonment" includes terms imposed by state courts). See also Beaty, 556 U.S., at ___, 129 S.Ct., at 2189 (the word "any" in "any other provision of law" was "no warrant to limit the class of provisions of law"). But our decision on the petitions of Abbott and Gould does not turn on artificial confinement of the phrase "any other provision of law." We rely, instead, on the different direction Congress prescribed for the "except" clause: It applies only when "a greater minimum sentence is otherwise provided." "In the contest between reading" that phrase "to refer to penalties for the [§ 924(c)] offense in question or to penalties for any [other] offense [a defendant commits], we believe the former is the most natural." Easter, 553 F.3d, at 526.9
