    UNITED STATES of America, Appellee, v. David Paul GAMMONS, Appellant.
    No. 02-1003.
    United States Court of Appeals, Eighth Circuit.
    Submitted: Sept. 27, 2002.
    Filed: Oct. 2, 2002.
    Before WOLLMAN, MORRIS SHEPPARD ARNOLD, and MELLOY, Circuit Judges.
   PER CURIAM.

David Paul Gammons pleaded guilty to conspiring to distribute methamphetamine, distributing methamphetamine, and possessing methamphetamine with intent to distribute, in violation of 21 U.S.C. §§ 841(a)(1), 841(b)(1)(A)-(C), and 846. The district court sentenced him to a total of 168 months of imprisonment and 5 years of supervised release. On appeal, counsel has filed a brief and moved to withdraw as to all but one issue under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). Gammons has filed a pro se supplemental brief.

Gammons is foreclosed from raising claims that he should have received a 3-level, rather than a 2-level, aeceptance-ofresponsibility reduction; that he should have been sentenced based on a smaller amount of methamphetamine; and that he should not have received a 3-level increase for his role in the offense. Gammons withdrew his objections to the presentence report (PSR) on these grounds at sentencing in exchange for the 2-level reduction and a recommendation for a 168-month sentence. See United States v. Gutierrez, 130 F.3d 330, 332 (8th Cir.1997) (right that is intentionally relinquished extinguishes claim altogether); United States v. Durham, 963 F.2d 185, 187 (8th Cir.) (defendant who voluntarily exposes himself to specific sentence may not challenge that punishment on appeal), cert. denied, 506 U.S. 1023, 113 S.Ct. 662, 121 L.Ed.2d 587 (1992). In any event, as to the aeceptaneeof-responsibility claim that counsel believes is meritorious, Gammons did not meet the conditions for the additional reduction because he did not present evidence that his proffer statement was either timely or complete. See U.S.S.G. § 3E1.1(b); United States v. Robinson, 73 F.3d 747, 754 & n. 8 (7th Cir.1996) (district court did not err in denying additional reduction when defendant did not show that she timely demonstrated acceptance of responsibility).

Gammons further argues that for a variety of reasons the district court lacked jurisdiction to sentence him to more than 10 years. His arguments fail because the district court properly adopted the factual findings in the PSR, see United States v. Beatty, 9 F.3d 686, 690 (8th Cir.1993) (district court may accept as true all factual allegations in PSR not specifically objected to); the district court stated its reasons for imposing the 168-month sentence; and his sentence did not exceed the applicable statutory maximum, see United States v. Aguayo-Delgado, 220 F.3d 926, 932 (8th Cir.), cert. denied, 531 U.S. 1026, 121 S.Ct. 600, 148 L.Ed.2d 513 (2000). Gammons’s pro se allegation of Federal Rule of Criminal Procedure 11 violations fails, as he was properly informed of the nature of the charge, and of the applicable statutory maximum and minimum penalty for each count. His ineffective-assistance claims are not properly raised on direct appeal. See United States v. Cain, 134 F.3d 1345, 1352 (8th Cir.1998).

Following our independent review, see Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we find no nonfrivolous issues. Accordingly, we grant counsel’s motion to withdraw, we deny Gammons’s motion to supplement the record, and we affirm. 
      
      . The Honorable Catherine D. Perry, United States District Judge for the Eastern District of Missouri.
