Kenny Halfacre appeals the district court’s 1 preservice dismissal, without prejudice, of his 42 U.S.C. § 1983 action based on alleged deprivations of his liberty interests. Having carefully reviewed the record and Halfacre’s arguments on appeal, we find no basis for reversal. See Moore v. Sims, 200 F.3d 1170, 1171 (8th Cir. 2000) (per curiam) (28 U.S.C. § 1915(e)(2)(B)(ii) dismissal is reviewed de novo); see also Sandin v. Conner, 515 U.S. 472, 483-84, 115 S.Ct. 2293, 132 L.Ed.2d 418 (1995) (alleged deprivation of liberty interest *965 must impose atypical and significant hardship in relation to ordinary incidents of prison life); Phillips v. Norris, 320 F.3d 844, 846-47 (8th Cir. 2003) (demotion to segregation, even without cause, is not itself atypical and significant hardship; prisoner has no federal constitutional liberty interest in having prison officials follow prison regulations); cf. Moody v. Daggett, 429 U.S. 78, 88 n. 9, 97 S.Ct. 274, 50 L.Ed.2d 236 (1976) (federal prisoner had no statutory or constitutional entitlement to particular classification). Accordingly, the judgment is affirmed. See 8th Cir. R. 47B.
