PER CURIAM:

Daquan Tyrek Brown seeks to appeal the district court’s order denying his Fed. R. Civ. P. 60(b) motion for reconsideration of the district court’s orders denying relief on his 28 U.S.C. § 2255 (2012) motion as well as a motion for modification of sentence, 18 U.S.C. § 3582(c) (2012). To the extent that Brown seeks to appeal the denial of relief as to his § 2255 motion, the order is not appealable unless a circuit justice or judge issues a certificate of appealability. 28 U.S.C. § 2253(c)(1)(B) (2012). A certificate of appealability will not issue absent “a substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2) (2012). When the district court denies relief on the merits, a prisoner satisfies this standard by demonstrating that reasonable jurists would find that the district court’s assessment of the constitutional claims is debatable or wrong. Slack v. McDaniel , 529 U.S. 473, 484 (2000); see Miller-El v. Cockrell , 537 U.S. 322, 336-38 (2003). When the district court denies relief on procedural grounds, the prisoner must demonstrate both that the dispositive procedural ruling is debatable, and that the motion states a debatable claim of the denial of a constitutional right. Slack , 529 U.S. at 484-85.

We have independently reviewed the record and conclude that Brown has not made the requisite showing. Accordingly, we deny a certificate of appealability and dismiss the appeal as to the denial of § 2255 relief.

To the extent that Brown seeks to appeal the denial of reconsideration of the denial of relief on his § 3582(c) motion, we have reviewed the record and find no reversible error. Accordingly, we affirm as to the denial of § 3582(c) relief. We dispense with oral *3 argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.
