MEMORANDUM **

William Aills appeals his 63-month sentence imposed after his guilty plea to possession of a firearm by a prohibited person, in violation of 18 U.S.C. § 922(g)(1). We have jurisdiction pursuant to 28 U.S.C. § 1291, and we remand.

Because appellant was sentenced under the then-mandatory Sentencing Guidelines, and we cannot reliably determine from the record whether the sentence imposed would have been materially different had the district court known that the Guidelines were advisory, we remand to the sentencing court to answer that question, and to proceed pursuant to United States v. Ameline, 409 F.3d 1073, 1084-85 (9th Cir. 2005) (en banc). See United States v. Moreno-Hernandez, 419 F.3d 906 (9th Cir. 2005) (extending Ameline’s limited remand procedure to cases involving non-constitutional Booker error).

REMANDED.
