Willie Lee Dumas, Jr. pled guilty to one count of armed robbery in violation of 18 U.S.C. § 2113(a),(d) (2000) and the use of a “deadly weapon” in the commission of that offense. Dumas was sentenced based on a base offense level of twenty-four, pursuant to the United States Sentencing Guidelines Manual (“USSG”) § 2D3.1(2) (2003), enhanced two levels under USSG § 2B3.1(b)(l) because property of a financial institution was taken, and enhanced five levels under USSG § 2B3.1(b)(2)(C) because a firearm was brandished or possessed during the offense. Citing Blakely v. Washington, — U.S. -, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), Dumas objected on the basis that he should only have been subject to a three-level guideline enhancement for use of a deadly weapon, see USSG § 2B3.1(b)(2)(E), not a five-level enhancement for use of a firearm, because the facts underlying the five-level enhancement were not found by a jury and *607 because Dumas pled guilty only to an unspecified “dangerous weapon.”

We agree with Dumas that the district court erred in imposing a sentence based on facts not found by a jury or admitted by Dumas, in violation of the Sixth Amendment. See United States v. Booker, — U.S. -, -, 125 S.Ct. 738, 756, 160 L.Ed.2d 621 (2005). 1 However, we reject Dumas’ contention that Blakely deprived the district court of the authority to impose a term of supervised release.

In view of the Supreme Court’s holding in Booker, and because Dumas does not challenge the validity of his conviction, we therefore affirm the conviction, vacate the sentence and remand for resentencing. 2 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.

AFFIRMED IN PART, VACATED IN PART, AND REMANDED
