Before WOLLMAN, McMILLIAN, and RILEY, Circuit Judges.
                         ___________

PER CURIAM.

      Dale D. Mitchell, Jr., appeals from the final judgment entered in the District
     1
Court for the Western District of Missouri after he pleaded guilty to a firearms
offense. The district court sentenced Mitchell to 86 months imprisonment and 3 years
supervised release. Counsel has filed a brief pursuant to Anders v. California, 

(1967), arguing the district court erred in imposing a 4-level enhancement
under U.S.S.G. § 2K2.1(b)(5) based on Mitchell’s possession of the firearm in
connection with another felony offense (aggravated assault), because the facts

District of Missouri.
underlying the aggravated assault were in dispute and the government failed to satisfy
its burden of proof that Mitchell possessed the firearm in connection with the
aggravated assault. Mitchell has filed a pro se supplemental brief, arguing the section
2K2.1(b)(5) enhancement violates his Sixth Amendment rights, citing Blakely v.
Washington, 

(2004), and challenging the sentencing court’s use of
his prior conviction for second-degree robbery to determine his base offense level.
For the reasons discussed below, we affirm the judgment of the district court.

      In pleading guilty, Mitchell expressly waived the right to appeal his sentence
on any ground except for an upward departure, a sentence in excess of the statutory
maximum, or a sentence in violation of law apart from the federal Sentencing
Guidelines. We enforce this appeal waiver, concluding no miscarriage of justice
would result from such enforcement because the district court conducted a proper
Fed. R. Crim. P. 11 colloquy at the plea hearing, Mitchell indicated his plea was
voluntary and knowing, his adjusted offense level was consistent with what the plea
agreement contemplated, and the court mentioned and explained the waiver at the
plea hearing and asked Mitchell if he understood the plea agreement, which included
the waiver the court had just explained. See United States v. Andis, 

,
889-91 (8th Cir.) (en banc) (court should enforce appeal waiver and dismiss appeal
where it falls within scope of waiver, both plea agreement and waiver were entered
into knowingly and voluntarily, and no miscarriage of justice would result; one
important way district court can ensure plea agreement and appeal waiver are
knowing and voluntary is to properly question defendant about decision to enter
agreement and to waive right to appeal), cert. denied, 

(2003).

       Our enforcement of the appeal waiver bars all of the arguments on appeal,
except for Mitchell’s pro se argument that the section 2K2.1(b)(5) enhancement
violates his Sixth Amendment rights as set forth in Blakely. Because Mitchell did not
object to this enhancement at sentencing, our review is for plain error. See United
States v. Gonzales, 

, 728 (8th Cir. 2003) (standard of review). We see

                                         -2-
none given that Mitchell waived his right to have a jury determine the enhancement
issue by stipulating to the 4-level increase in his plea agreement, and by not objecting
to the PSR’s description of the offense (aggravated assault) conduct. See 

(nothing prevents defendant from waiving his Apprendi v. New
Jersey, 

(2000), rights; when defendant pleads guilty, government is free
to seek judicial sentence enhancements so long as defendant either stipulates to
relevant facts or consents to judicial factfinding).

      Following our independent review, see Penson v. Ohio, 

(1988), we
find no nonfrivolous issues. Accordingly, we affirm.
