Tyrees C. Whitehead seeks a writ of mandamus compelling the district court to consider his application for post-conviction relief as an initial petition filed pursuant to 28 U.S.C. § 2241 (1994), rather than as a successive petition under section 2255 of the same title. Whitehead maintains that [*229] his two convictions of violating 18 U.S.C.A. § 924(c)(1) (West Supp.2000) must be vacated in light of the recent decisions of the Supreme Court in Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000), and Castillo v. United States, 530 U.S. 120, 120 S.Ct. 2090, 147 L.Ed.2d 94 (2000).

The cited authorities are inapposite to Whitehead’s claims. Inasmuch as section 924(c)(1) prescribes no statutory maximum, Whitehead’s sentence does not implicate Apprendi. See 530 U.S. at 489, 120 S.Ct. 2348; United States v. Harris, 243 F.3d 806, 809 (4th Cir.2001). Moreover, Whitehead has not shown how Castillo (in which the Court concluded that enhanced penalties for particular firearms constitute separate crimes under § 924(c)(1)) bears on his situation, i.e., where the enhanced sentence was imposed as a result of a second conviction under the statute. Consequently, Whitehead cannot demonstrate a clear right to relief justifying issuance of the writ. See Allied Chem. Corp. v. Daiflon, Inc., 449 U.S. 33, 35, 101 S.Ct. 188, 66 L.Ed.2d 193 (1980).

Accordingly, we grant Whitehead’s motion for leave to proceed in forma pauperis, but we deny his petition for a writ of mandamus directing the district court to consider the underlying claims pursuant to § 2241. * We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before us, and argument would not aid the decisional process.

PETITION DENIED.
