Eric Lee Evans appeals the sentence imposed following his guilty-plea conviction for possession of a firearm by a convicted felon in violation of 18 U.S.C. §§ 922(g)(1) and 924(a)(2). Evans argues that, in light of United States v. Booker, — U.S.-, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), the district court erred in sentencing him under a mandatory guidelines system and in sentencing him based upon facts that were not admitted by him or found by a jury.

The two-level adjustment to Evans’s sentence pursuant to U.S.S.G. § 2K2.1(b)(4) violated his Sixth Amendment right to a trial by jury, and the Government has not carried its burden of demonstrating that the error was harmless. See United States v. Pineiro, 410 F.3d 282, 286 (5th Cir. 2005); United States v. Akpan, 407 F.3d 360, 376-77 (5th Cir. 2005). Accordingly, Evans’s sentence is VACATED, and the case is REMANDED FOR RESENTENCING. Because it is necessary to vacate Evans’s sentence based upon the Sixth Amendment Booker error, we do not address Evans’s argument that his sentencing pursuant to a mandatory guidelines scheme constitutes reversible error. See Akpan, 407 F.3d at 377 n. 62.
