Christopher Mark Kern appeals the 120-month prison sentence the district court 1 imposed after he pleaded guilty to being a felon in possession of a firearm and ammunition, in violation of 18 U.S.C. § 922(g)(1), and a forfeiture count. His counsel has moved to withdraw and has filed a brief under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), arguing that the sentence is unreasonable.

We conclude that the district court committed no procedural error and imposed a substantively reasonable sentence. See Gall v. United States, 552 U.S. 38, 51, 128 *33 S.Ct. 586, 169 L.Ed.2d 445 (2007) (in reviewing sentence, appellate court first ensures that district court committed no significant procedural error, then considers substantive reasonableness of sentence under abuse-of-discretion standard; if sentence is within applicable Guidelines range, appellate court may apply presumption of reasonableness); United States v. Haack, 403 F.3d 997, 1004 (8th Cir. 2005) (describing abuse of discretion).

Having reviewed the record under Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we have found no non-frivolous issues. Accordingly, we grant counsel’s motion to withdraw, and we affirm.
