Rashad Jacobs and Rasul Gatford each pled guilty, pursuant to a plea agreement, to brandishing a firearm during a drug trafficking crime, in violation of 18 U.S.C. §§ 2, 924(c) (2012). The district court sentenced them to 120 months’ imprisonment, an upward variance of 36 months from the Sentencing Guidelines range. See U.S. Sentencing Guidelines Manual § 2K2.4(b) (2013). Jacobs and Gatford appeal, claiming that their sentences are substantively unreasonable. We affirm.

We review the district court’s sentence, “whether inside, just outside, or significantly outside the Guidelines range[,]” for reasonableness “under a deferential abuse-of-diseretion standard.” Gall v. United States, 552 U.S. 38, 41, 51, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007). Because Jacobs and Gatford do not challenge the procedural reasonableness of their sentences, we turn our attention to substantive reasonableness and consider “the totality of the circumstances, including the extent of any variance from the Guidelines range.” Id. at 51, 128 S.Ct. 586. An upward variance is permitted where justified by the 18 U.S.C. § 3553(a) (2012) factors. See id. We “must give due deference to the district court’s decision that the § 3553(a) factors, on a whole, justify the extent of a variance,” and “[t]he fact that [we] might reasonably have concluded that a different sentence was appropriate is insufficient to justify reversal of the district court.” Id.

Jacobs and Gatford assert that the district court improperly relied upon the need to avoid unwarranted sentencing disparities under 18 U.S.C. § 3553(a)(6) to the exclusion of the other statutory sentencing factors. We disagree. The district court described how Appellants’ individual actions were more culpable than those of defendants with similar charges and were analogous to discharging a firearm. We also conclude that the court did not improperly rely upon the sentence imposed on a codefendant to determine the length of the variance.

Jacobs and Gatford also argue that their sentences are contrary to Congress’ intent for different mandatory minimum sentences to apply to brandishing and discharging a firearm. However, Congress left district courts with the option of imposing sentences of seven years or more *252 for brandishing a firearm if the facts so warranted. See 18 U.S.C. § 924(c)(1)(A) (declining to set maximum sentence). Therefore, Congress’ intent in formulating § 924(c) does not render unreasonable the district court’s imposition of 120-month sentences under § 924(c)(i)(A)(ii). *

Accordingly, we hold that the upward variance imposed by the district court is substantively reasonable, and we affirm the judgment of the district court. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.

AFFIRMED.
