The only conviction at issue in this appeal is for violating 18 U.S.C. § 924(c) by possessing firearms in furtherance of a drug-trafficking crime. 1 He makes two interrelated arguments: (1) that there was insufficient evidence to convict him, and (2) that the “in furtherance of” language in § 924(c) was unconstitutionally vague as applied to him.

And in the back-seat area they found a Ziploc bag containing 84 grams of methamphetamine. At trial the government introduced expert testimony that Defendant’s firearms functioned as designed, that the amount of methamphetamine he possessed was consistent with distribution and worth up to $10,800, and that drug
