Andre Leffebre, an inmate confined at the United States Penitentiary at Beaumont, Texas, proceeding pro se and in-forma, pauperis, appeals the dismissal of his suit for damages arising from his conviction and incarceration of being a felon in possession of a firearm. That conviction has not been reversed, expunged, invalidated, or called into question by the issuance of a writ of habeas corpus, and the district court properly dismissed the instant action for failure to state a claim upon which relief may be granted. Heck v. Humphrey, 512 U.S. 477, 486-87, 114 *354 S.Ct. 2364, 129 L.Ed.2d 383 (1994). Leffe-bre’s appeal is frivolous and without arguable merit, and is accordingly dismissed. See 5th Cir R. 42.2.

The district court’s dismissal of Leffe-bre’s action and this Court’s dismissal of his appeal count as two strikes under 28 U.S.C. § 1915(g). See Adepegba v. Ham-mons, 103 F.3d 383, 387-88 (5th Cir. 1996). Leffebre accumulated additional strikes for the dismissal of similar claims in Leffe-bre v. Carter, No. 3:06-CV-149, 2007 WL 4206180 (S.D.Tex., Nov. 26, 2007) and Leffebre v. Cothren, No. 3:06-CV-150, 2007 WL 4198554 (S.D.Tex., Nov. 26, 2007). As Leffebre has now accumulated at least three strikes under § 1915, he is barred from proceeding in forma pauperis while he is incarcerated or detained in any facility unless he is under imminent danger of serious physical injury. See § 1915(g).

APPEAL DISMISSED; 28 U.S.C. § 1915(G) BAR IMPOSED.
