*634MEMORANDUM **

William Gene Scribner appeals his conviction and sentence for possession of a listed chemical with intent to manufacture a controlled substance in violation of 21 U.S.C. § 841(c)(1). We have jurisdiction under 28 U.S.C. § 1291, and we affirm his conviction. We remand his sentence under United States v. Ameline.1 Because the parties are familiar with the facts, we do not recount them here.

The district court properly denied Scribner’s motion to dismiss based on outrageous government conduct.2 The Government’s conduct was not outrageous because the Government did not “initiate the criminal activity,” but merely worked in concert with Scribner and his co-defendant.3

The district court properly denied Scribner’s request for a jury instruction on entrapment.4 An entrapment instruction was not warranted because no evidence indicated that the Government induced Scribner to participate in criminal activity.5 Accordingly, we affirm Scribner’s conviction.

We review Scribner’s unpreserved Booker claim for plain error.6 We cannot determine from the record whether the district court would have imposed a materially different sentence if it had known that the Guidelines were advisory, as the Supreme Court held in United States v. Booker.7 Therefore, under Armline, we remand for the limited purpose of making that determination.8 In fulfilling this mandate, the district court may hold such hearings and enter such orders as it determines to be necessary, including, without limitation, modifying or vacating its previous sentence.

Conviction AFFIRMED; Sentence REMANDED.
