While serving a period of supervised release on a federal criminal sentence, Charles Southern admitted to the district court 1 that he had violated his release *669 conditions. The court revoked supervised release and imposed a revocation sentence of 5 months in prison — a sentence falling below the advisory Guidelines revocation range — and 41 months of additional supervised release. Mr. Southern appeals, and argues for reversal that the sentence is substantively unreasonable.

Upon careful review of the record before us, we reject Mr. Southern’s argument, and conclude that the sentence is substantively reasonable. See United States v. Miller, 557 F.3d 910, 917 (8th Cir. 2009). Accordingly, the judgment is affirmed, and we grant counsel leave to withdraw.
