Noe Delarosa appeals from his conviction of illegal possession of a machine gun and aiding and abetting. He argues that the district court erred by denying him a three-level downward adjustment to his offense level pursuant to U.S.S.G. § 3E1.1 for acceptance of responsibility. He asserts that the district court incorrectly characterized as frivolous his objection to a four-level upward adjustment under § 2K2.1 (b)(6)(A) for knowing or having reason to know that the firearms his group purchased from undercover agents were intended to be transported to Mexico.

*626 The denial of the adjustment for acceptance of responsibility was not without foundation. See United States v. Juarez-Duarte, 513 F.3d 204, 211 (5th Cir. 2008). First, Delarosa refused to answer questions during his interview with the probation officer about the destination of the firearms or the purpose for which they were being purchased. Second, the transcripts of surveillance videos indicated that Delarosa either knew or should have known that the firearms were destined for Mexico.

AFFIRMED.
