OPINION

Petitioner Monroe Bullock petitions this Court for a writ of mandamus directing the District Court to impose a reduced sentence on his conviction for conspiracy to distribute cocaine base. Bullock’s petition appears to be an attempt to file a successive motion under 28 U.S.C. § 2255. Thus, we will deny the petition.

I.

Bullock has previously pursued direct and collateral review in this Court. We affirmed his judgment of conviction and sentence in 1997. See United States v. Bullock, C.A. No. 96-1639, 1997 WL 626881 (3d Cir. Sept. 18, 1997). He then filed his first motion under 28 U.S.C. § 2255 in 1998, which the District Court denied. We denied a certificate of appeal-ability. United States v. Bullock, C.A. No. 99-1175, Order (3d Cir. Oct. 27, 1999). In 2001, Bullock filed his first application for permission to file a second or successive § 2255 motion, which we also denied. In re Bullock, C.A. No. 01-2655, Order (3d Cir. Aug. 29, 2001).

II.

On June 22, 2005, Bullock filed the instant mandamus request raising two arguments: (1) the District Court found facts not supported by the record; and (2) the District Court erred in enhancing his sentencing score based on a finding that Bullock used a firearm in connection with a drug offense.

A writ of mandamus is an extraordinary remedy which should be invoked rarely. 1 See Kerr v. United States Dist. Ct. for N. Dist. of Cal., 426 U.S. 394, 402, 96 S.Ct. 2119, 48 L.Ed.2d 725 (1976). Bullock must show that he has an indisputable right to the writ and that there exists no other adequate remedy. See Haines v. Liggett Group Inc., 975 F.2d 81, 89 (3d Cir. 1992).

A § 2255 motion is the presumptive means for a federal prisoner to challenge the fact or duration of a conviction or sentence, unless such a motion would be “inadequate or ineffective to test the legality of his detention.” Okereke v. United States, 307 F.3d 117, 120 (3d Cir. 2002); 28 U.S.C. § 2255 ¶ 5. A § 2255 motion is inadequate or ineffective only when “some limitation of scope or procedure” prevents a movant from receiving an adjudication of *140 his claim. Cradle v. United States ex rel. Miner, 290 F.3d 536, 538 (3d Cir. 2002). Section 2255 is not “inadequate or ineffective” merely because the sentencing court previously denied relief or because the gatekeeping provisions of § 2255 make it difficult to pursue a successive motion. Id. at 539; see also In re Dorsainvil, 119 F.3d 245, 251 (3d Cir. 1997).

Upon thoroughly reviewing Bullock’s request, we find that he directly challenges the fact of his conviction and the duration of his sentence. He thus fails to show that there exists no other adequate remedy. We recognize that Bullock would not now be entitled to file a second or successive § 2255 motion raising the instant claims. See 28 U.S.C. § 2255 ¶ 7. However, as explained in Cradle, just because Bullock cannot meet the stringent standards of the revised § 2255 does not mean that he may now pursue his claims through a request for a writ of mandamus.

Accordingly, his petition for a writ of mandamus will be denied.
