Unpublished opinions are not binding precedent in this circuit.2 PER CURIAM: Thomas Lee Brincefield appeal s his 121

- month sentence imposed after pleading guilty to distribution of heroin , in violation of 21 U.S.C. § 841 ( a ) (1), (b)(1)(C) (2012 ), and possession of a firearm by a convicted felon , in violation of 18 U.S.C. § § 922 ( g ) (1), 924(a)(2) (2012)

. Brincefi eld’s counsel has filed a brief pursuant to Anders v. California , 386 U.S. 738 (1967), certifying that there are no meritorious issues for appeal , but questioning whether the district court properly applied a two

- level Sentencing Guidelines premises enhancement and properly calculated the drug quantity attributable to Brincefield

. Brincefield has file d a pro se supplemental brief also challenging the drug quantity and contending that his appellate waiver is invalid, his criminal history score is inco rrect, the district court improperly applied a two

- level Guidelines enhancement for possessing a firearm, and his attorney rendered constitutionally ineffective assistance. The Government has moved to dismiss Brincefield’s appeal , invoking the appellate

w aiver contained in Brincefield’s plea agreement. We grant the Government’s motion to dismiss in part , dismiss the appeal in part, and affirm in part. We review the validity of an appellate waiver de novo and “will enforce the waiver if it is valid and the issue appealed is within the scope of the waiver.” United
States v. Adams , 814 F.3d 178, 182 (4th Cir. 2016). An appellate waiver must be knowing and voluntary. Id. We generally evaluate the validity of a waiver by reference to the totality of the cir cumstances. United States v. Thornsbury , 670 F.3d 532, 537 (4th Cir. 2012). “In the absence of extraordinary circumstances, a properly conducted [Fed. R. Crim. P.] 11 colloquy establishes the validity of the waiver.” Adams , 814 F.3d at 182.3 Upon review of the plea agreement and the transcript of the Rule 11 hearing, we conclude that Brincefield knowingly and voluntarily waived his right to appeal his sentence, and that the sentencing issues Brincefield seeks to raise on appeal fall squarely within the co mpass of his waiver of appellate rights. Accordingly, we grant the Government’s motion to dismiss in part and dismiss Brincefield’s appeal as to his sentencing claims

. In accordance with Anders , we have reviewed the entire record in this case and have ide ntified no unwaived meritorious issues for appeal. To the extent Brincefield argues that his attorney w as ineffective, we conclude that ineffective assistance of counsel does not conclusively appear from the record and, thus, we decline to address this cl aim on direct appeal. United States v. Baptiste , 596 F.3d 214, 216 n.1 (4th Cir. 2010). Brincefield’s ineffective assistance of counsel claims are more appropriately raised, if at all, in a 28 U.S.C. § 2255 (2012) motion. See United States v. Baldovinos , 434 F.3d 233, 239 & n.4 (4th Cir. 2006). We therefore affirm the remainder of the judgment of the district court . This court requires that counsel inform Brincefield , in writing, of the right to petition the Supreme Court of the United States for furth er review. If Brincefield requests that a petition be filed, but counsel believes that such a petition would be frivolous, then counsel may move in this court for leave to withdraw from representation. Counsel’s motion must state that a copy thereof was served on Brincefield

.4 We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process. DISMISSED IN PART, AFFIRMED IN PART
