Before MELLOY, HANSEN, and COLLOTON, Circuit Judges.
                           ___________

PER CURIAM.

       Charles Johnson appeals the sentence the district court1 imposed after he
pleaded guilty to a drug charge. Following our review of counsel’s brief filed under
Anders v. California, 386 U.S. 738 (1967), as well as Johnson’s pro se supplemental
brief, we conclude that Johnson cannot challenge an offense-level enhancement for
possession of a dangerous weapon after stipulating to such an enhancement in the
plea agreement, see United States v. Nguyen, 46 F.3d 781, 783 (8th Cir. 1995), and

      1
       The Honorable George Howard, Jr., United States District Judge for the
Eastern District of Arkansas.
that his ineffective-assistance arguments would be more properly raised in a collateral
proceeding, see United States v. Cain, 134 F.3d 1345, 1352 (8th Cir. 1998). In
addition, we have reviewed the record independently for nonfrivolous issues under
Penson v. Ohio, 488 U.S. 75 (1988), and we find none.

      Accordingly, we affirm. Counsel’s motion to withdraw is granted.
                     ______________________________
