John Mark Richardson pled guilty to being a felon in possession of a weapon under 18 U.S.C. § 922(g)(1) (2000). Both his plea agreement and plea hearing reveal that Richardson was informed that the Government considered him an armed career criminal under 18 U.S.C.A. § 924(e) (West Supp. 2005) and that his minimum sentence under the statute was fifteen years of imprisonment.

Counsel conceded at Richardson’s sentencing hearing that the designation was proper but argued that the sentencing enhancement was invalid in light of the Supreme Court’s decision in Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004). The district court sentenced Richardson to 180 months of imprisonment, the mandatory minimum under § 924(e). Since Richardson’s appeal, the Supreme Court has extended its decision in Blakely to federal criminal defendants. See United States v. Booker, — U.S. -, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005) (striking down the mandatory provisions of the Federal Sentencing Guidelines). On appeal, Richardson argues (1) that the sentence is invalid in light of Blakely and (2) that his criminal history, as calculated in his presentence report, is also invalid. For the reasons that follow, we affirm.

Richardson has preserved his Blakely arguments for appellate review. He first alleges that his armed career criminal designation does not survive Blakely. Richardson, however, does not deny the fact of his five prior North Carolina convictions for “Felonious Robbery With a Dangerous Weapon” or that such convictions are a proper predicate for the armed career criminal enhancement he received. Because Richardson’s fifteen-year sentence was mandated by statute, the then-mandatory sentencing guidelines did not affect his sentence. Accordingly, we find there is no error under Booker. See United States v. Robinson, 404 F.3d 850, 862 (4th Cir. 2005) (“Booker did nothing to alter the rule that judges cannot depart below a statutorily provided minimum sentence.”). Moreover, we recently rejected the argument that a defendant’s Sixth Amendment rights are violated under Booker when his sentence is statutorily enhanced under § 924(e). See United States v. Cheek, 415 F.3d 349 (4th Cir. 2005).

Second, Richardson alleges that his criminal history, as calculated in his presentence report, was erroneous in light of Blakely. This claim fails, however, as Richardson’s sentence was not increased based on his criminal history. Rather, Richardson was sentenced to the mandatory minimum sentence under § 924(e).

Thus, we affirm Richardson’s conviction and sentence. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
