Clayton W. Hackney pled guilty to manufacturing methamphetamine, in violation of 21 U.S.C. § 841(a)(1) (2000); possession of a firearm while an unlawful user of a controlled substance, in violation of 18 U.S.C. §§ 922(g)(3), 924(a)(2) (2000); and *543 possession of an unregistered firearm, in violation of 26 U.S.C. §§ 5861(d), 5871 (2000). His sentencing occurred on March 21, 2005, after the Supreme Court’s decision in United States v. Booker, — U.S. ——, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), ruling that its decision in Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), was applicable to the federal sentencing guidelines. The district court, in sentencing Hackney, carefully and thoroughly applied the holding in Booker. The court sentenced Hackney to sixty-three months of imprisonment, followed by three years of supervised release.

On appeal, Hackney raises one issue, which he did not raise in the district court. He argues that his due process rights, as informed by ex post facto principles, are violated by the imposition of a sentence under the Supreme Court’s remedial decision in Booker (referring to the Court’s opinion expressed through Justice Breyer, which makes the guidelines advisory rather than mandatory), rather than under the mandatory guidelines applicable at the time of his offense. Reviewing this claim for plain error, we find none. See United States v. Olano, 507 U.S. 725, 731-32, 113 S.Ct. 1770, 123 L.Ed.2d 508 (1993) (plain error standard); United States v. Jamison, 416 F.3d 538 (7th Cir. 2005) (rejecting ex post facto claim); United States v. Lata, 415 F.3d 107 (1st Cir. 2005) (same); United States v. Scroggins, 411 F.3d 572, 576 (5th Cir. 2005) (same); United States v. Duncan, 400 F.3d 1297 (11th Cir. 2005) (same), petition for cert. filed, — U.S. -, — S.Ct. -, — L.Ed.2d - (U.S. July 20, 2005) (No. 05-5467).

Having found that Hackney failed to establish plain error under the Olano standard, we affirm his sentence. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
