Lorenzo Prado appeals his sentence following his guilty plea conviction for possession with intent to distribute 255 kilograms of marijuana, a violation of 21 U.S.C. § 841.

Prado contends that § 841 is unconstitutional in light of Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000). As Prado concedes, his argument is foreclosed by circuit precedent. See United States v. Slaughter, 238 F.3d 580, 582 (5th Cir.2000). He raises the issue only to preserve it for Supreme Court review.

Prado also contends that the district court erred by finding that his prior Texas state conviction for burglary of a habitation constitutes a “crime of violence” for purposes of the career offender enhancement provision of U.S.S.G. § 4B1.1. The district court correctly found that Prado’s prior conviction for burglary of a habitation was a conviction for a crime of violence under § 4B1.2(a). See United States v. Hornsby, 88 F.3d 336, 339 (5th Cir. 1996); see also United States v. Garcia- Mendez, 420 F.3d 454, 456-57 (5th Cir. 2005) (applying Hornsby to enhancement pursuant to § 2L1.2(b)(l)(A)(ii)).

Finally, although the district court’s imposition of a sentence of 188 months of imprisonment was within the applicable guidelines range, Prado contends that the sentence was unreasonable under United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). This court recently held that a discretionary sentence imposed within a properly calculated guideline range is presumptively reasonable. See United States v. Alonzo, 435 F.3d 551 (5th Cir.2006). Prado has not rebutted the presumption that his sentence was reasonable.

AFFIRMED.
