Defendant-Appellant Fernando Mangui-la-Paez appeals his sentence for possession with the intent to distribute methamphetamine, distribution of methamphetamine, and possession of a firearm during a drug trafficking crime. 21 U.S.C, § 841(a), (b)(1)(C); 18 U.S.C. § 924(c)(1)(A). The district court sentenced him within the guidelines range to a total of 157 months of imprisonment. Manguila-Paez challenges the district court’s denial of a mitigating role reduction under U.S.S.G. § 3B1.2.

Whether a defendant was a minor or minimal participant is a factual question that we' review for clear error. United States v. Gomez-Valle, 828 F.3d 324, 328 (5th Cir. 2016)., A district court need not expressly weigh each factor in deciding whether to grant a mitigating role reduction. United States v. Torres-Hernandez, 843 F.3d 203, 209 (5th Cir. 2016). Mangui-la-Paez drove a vehicle to a location where he picked up another co.conspirator, and they traveled together to a preplanned, secondary location where they intended to sell approximately one pound of methamphetamine to a buyer who, unbeknownst to them, was an undercover agent. In denying Manguila-Paez a § 3B1.2 adjustment, the district court relied on the fact that (1) he understood the nature of the transaction and his role in it, (2) a large quantity of methamphetamine was involved; (3) he was armed in case trouble ensued; and (4) he had previously been involved in drug transactions with one of his codefendants. The district court did not err in relying on these factors in refusing to grant Mangui-la-Paez a § 3B1.2 adjustment. See United States v. Jimenez, 687 Fed.Appx. 395, 398 (5th Cir. 2017); United States v. Ramirez-Esparza, 703 Fed.Appx. 276, 278, 279 n.3 (5th Cir. 2017).

Moreover, Manguila-Paez has failed to satisfy his burden of establishing the culpability of an average participant and that he was substantially less culpable than the average participant. See United States v. Castro, 843 F.3d 608, 613 (5th Cir. 2016). The district court’s finding that Manguila-Paez was not substantially less culpable than the average participant was thus plausible in light of the record as a whole. § 3B1.2, comment. (n.3(A)); see Torres-Hernandez, 843 F.3d at 207.

AFFIRMED.
