Unpublished opinions are not binding precedent in this circuit.

Jackie Victor Adams, a federal prisoner, appeals the district court’s order accepting the magistrate judge’s recommendation to dismiss with prejudice Adams’ 28 U.S.C. § 2241 (2012) petition in which Adams sought to challenge his armed career criminal designation. We have reviewed the record and find no reversible error. Adams has failed to satisfy his burden of demonstrating that 28 U.S.C. § 2255 (2012) is an inadequate or ineffective means of challenging the validity of his detention. See Rice v. Rivera, 617 F.3d 802, 807 (4th Cir. 2010); United States v. Poole, 531 F.3d 263, 267 n.7 (4th Cir. 2008). As such, the district court lacked jurisdiction to consider the merits of Adams’ petition. Rice, 617 F.3d at 807. Accordingly, we grant leave to proceed in forma pauperis, modify the district court’s judgment to reflect that the dismissal of Adams’ petition is without prejudice, and affirm the district court’s judgment as modified. See S. Walk at Broadlands Homeowner’s Ass’n v. Open-Band at Broadlands, LLC, 713 F.3d 175, 185 (4th Cir. 2013). We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.
