MEMORANDUM **

Vincent Martinez appeals from the 353-month term of imprisonment imposed upon resentencing following his jury trial conviction for conspiracy to possess with intent to distribute methamphetamine, in violation of 21 U.S.C. §§ 841(a)(1) and 846, *793and use of a firearm during a drug trafficking crime, in violation of 18 U.S.C. § 924(c). We have jurisdiction pursuant to 28 U.S.C. § 1291.

Martinez challenges the district court’s enhancement based on drug quantity. Because this challenge was preserved below, we vacate the sentence and remand for resentencing under the now-advisory Guidelines. See United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005); United States v. Kortgaard, 425 F.3d 602, 610-11 (9th Cir. 2005).

Martinez’s motion for leave to file supplemental briefing is denied as moot.

SENTENCE VACATED and REMANDED.
