Federal inmate Ronald H. Brewster appeals from the district court’s 1 dismissal of his 28 U.S.C. § 2241 petition, in which he argued that his 168-month sentence for conspiring to distribute cocaine base is invalid under Apprendi v. New Jersey, 530 *718 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000). Having conducted careful de novo review, see United States v. Lurie, 207 F.3d 1075, 1076 (8th Cir. 2000), we agree with the district court that habeas relief was not warranted: not only did Brewster fail to show that a motion under 28 U.S.C. § 2255 was inadequate or ineffective to test the legality of his detention, but his arguments are foreclosed under United States v. Moss, 252 F.3d 993, 1001 (8th Cir. 2001), and United States v. Aguayo-Delgado, 220 F.3d 926, 933 (8th Cir.), cert. denied, 531 U.S. 1026, 121 S.Ct. 600, 148 L.Ed.2d 513 (2000).

Accordingly, we affirm. See 8th Cir. R. 47B.
