Aaron Alexander Boutte, federal prisoner # 09562-035, appeals the district court’s denial of his 18 U.S.C. § 3582(c)(2) motion to reduce the 324-month sentence he received following his guilty plea conviction for conspiracy to distribute and distribution of crack cocaine. Boutte contends that the district court’s denial of his § 3582(c)(2) motion was error. Although he concedes that, because he was held *5 accountable for more than 4.5 kilograms of crack cocaine, his guidelines range was unaffected by the retroactive crack cocaine amendments, he nevertheless urges that United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), Kim-brough v. United States, 552 U.S. 85, 128 S.Ct. 558, 169 L.Ed.2d 481 (2007), and Gall v. United States, 552 U.S. 38, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007), should apply in § 3582(c)(2) proceedings, allowing district courts to impose sentences lower than the two-level adjustment contemplated by the crack cocaine amendments based on the factors set forth in 18 U.S.C. § 3553(a).

We review the district court’s decision for an abuse of discretion. United States v. Boe, 117 F.3d 830, 831 (5th Cir. 1997). As Boutte concedes, because his offense involved more than 4.5 kilograms of crack cocaine, the retroactive crack amendment does not lower his guidelines range, and the district court did not abuse its discretion in refusing to reduce his sentence. See § 3582(c)(2); U.S.S.G. §§ 1B1.10, comment. (n.lA) and 2D1.1. Moreover, the Supreme Court’s decision in Booker does not apply to sentence reductions under § 3582(c)(2) because such proceedings are not full resentencings. United States v. Doublin, 572 F.3d 235, 238 (5th Cir.), cert. denied, — U.S.-, 130 S.Ct. 517, 175 L.Ed.2d 366 (2009); see also Dillon v. United States, — U.S.-,---, 130 S.Ct. 2683, 2691-93, 177 L.Ed.2d 271 (2010). Boutte’s argument based on Booker and its progeny is therefore unavailing.

AFFIRMED.
