Before WOLLMAN, BEAM, and HANSEN, Circuit Judges.
                          ___________

PER CURIAM.

       Mark Edward Wabasha pleaded guilty to being a felon in possession of a
firearm, in violation of 18 U.S.C. §§ 922(g)(1) and 2; to breaking into a United States
Post Office with the intent to commit a larceny and other depredation, in violation of
18 U.S.C. §§ 2115 and 2; and to stealing firearms from a licensed dealer, in violation
of 18 U.S.C. §§ 922(u) and 924(i)(1). The district court1 sentenced Wabasha to a total
of 180 months’ imprisonment and four years’ supervised release, and ordered

      1
      The Honorable Michael J. Melloy, Chief Judge, United States District Court for
the Northern District of Iowa.
restitution. This appeal followed. After appellate counsel moved to withdraw pursuant
to Anders v. California, 386 U.S. 738 (1967), we granted Wabasha permission to file
a pro se supplemental brief, and he has done so. We affirm.

       The Anders and pro se briefs each contain an argument that the district court
erred in classifying Wabasha as an armed career criminal because his prior convictions
were neither violent nor separate felonies as required for application of the 15-year
mandatory minimum sentence under 18 U.S.C. § 924(e)(1). We reject this argument,
as Wabasha stipulated in the plea agreement to his status as an armed career criminal
under section 924(e)(1) and to the resulting base offense level. See United States v.
Early, 77 F.3d 242, 244 (8th Cir. 1996) (per curiam) (defendant cannot challenge
Guidelines application on appeal where defendant&s plea agreement expressly sets forth
base offense level and defendant does not challenge validity of plea agreement); United
States v. Fritsch, 891 F.2d 667, 668 (8th Cir. 1989) (where defendant voluntarily
exposed himself to specific sentence and did not object in district court, he waived his
right to appeal punishment). To the extent Wabasha is alleging in his supplemental
brief that his counsel was ineffective, we conclude that this argument would be more
appropriately addressed in a 28 U.S.C. § 2255 proceeding where a record can be fully
developed. See United States v. Mitchell, 136 F.3d 1192, 1193 (8th Cir. 1998).

      Upon review of the record in accordance with Penson v. Ohio, 488 U.S. 75, 80
(1988), we find no nonfrivolous issues. Accordingly, the judgment is affirmed.

      A true copy.
