MEMORANDUM **

Roger Benson appeals from the 33-month sentence imposed following his guilty-plea conviction for escape from custody, in violation of 18 U.S.C. § 751. We have jurisdiction pursuant to 28 U.S.C. § 1291, and we affirm.

Benson contends that the district court plainly erred when it failed to give him credit for the time served on an undis *484 charged concurrent state sentence, under U.S.S.G. § 5G1.3(b)(l).

Benson’s contention lacks merit because the state sentence did not result from “relevant conduct,” see U.S.S.G § 1B1.3, and was not used to increase Benson’s base offense level. Cf. United States v. Armstead, 552 F.3d 769, 783-84 (9th Cir. 2008).

AFFIRMED.
