OPINION
Harris appeals from his sentence for violating 18 U.S.C. § 922(g)(1) (2006). Because Harris waived the right to bring the instant appeal, we refuse to exercise jurisdiction over Harris’s claims, and we dismiss his appeal.
I.
On March 10, 2008, Harris pleaded guilty, pursuant to a written plea agreement, to being a felon in possession of a firearm and ammunition in violation of 18 U.S.C. § 922(g)(1). At sentencing, the government requested that Harris’s sentence be enhanced pursuant to U.S.S.G. § 2K2.1(a) based on Harris’s previous first-degree burglary conviction in California state court. According to the government, Harris’s prior burglary conviction qualified for the enhancement as a “crime
Before addressing the merits of Harris’s claims, we must consider the government’s argument that this appeal should be dismissed based on the appeal waiver contаined in Harris’s plea agreement. Generally, appellate courts “ ‘re-taint ] subject matter jurisdiction over [an] appeal by a defendant who has signed an appellate waiver.’ ”
United States v. Jacobo Castillo,
II.
“ ‘[A] defendant’s wаiver of his appellate rights is enforceable if (1) the language of the waiver encompasses his right to appeal on the grounds raised, and (2) the waiver is knowingly and voluntarily made.’ ”
United States v. Charles,
When considering a criminal defеndant’s appeal waiver, “ ‘[o]ur analysis begins with the fundamental rule that plea agreements are contractual in nature and are measured by contract law standards.’ ”

In his plea agreement, Harris stipulated that section 2K2.1(a)(4)(A)’s “crime of violence” enhancement was applicable under the Guidelines. He further stipulated to a total offense level of seventeen, which included the enhancement at issue. He then expressly agreed to the following appeаl waiver:
Defendant gives up the right to appeal any sentence ... and the manner in which the sentence is determined, provided that (a) the sentence is within the statutory maximum ... and is constitutional, (b) the Court in determining the applicable guideline range does not depart upward in offense level or criminal history category and determines that the total offense level is [seventeen] or below, and (c) the Court imposes a sentence within or below the range corresponding to the determined total offense level and criminal history category.
In other wоrds, Harris waived his right to challenge a sentence within a guideline range, even if his sentence included the “crime of violence” enhancement.
The record fully supports the validity of Harris’s wаiver. Harris does not contend that his waiver was unknowing or involuntary. Furthermore, “[i]n addition to the written terms of the plea agreement itself, the district court ‘reviewed the charges and each of the terms of the plea agreement and asked [Harris] questions to ensure that he understood the contents of his plea agreement.’ ”

Notwithstanding the record of his waiver, Harris contends that the government later modified the plea agreement to permit appeal of the district court’s total offense-level determination. While Harris stipulated in the plea agreement that his prior first-degree burglary was a “crime of violence” under section 2K2.1(a)(4)(A), he points to an email communication wherein the government allowed him to withdraw that stipulation. The government apparently allowed Harris to retract this stipulation based on our now-withdrawn decision in
United States v. Aguila-Montes De Oca,
RE: the issue of HARRIS’ base offense level. We agree that you should be allowed to аrgue that the base offense level should be changed in his favor because there is new law on the topic since the plea agreement. I’ll still likely maintain that the offense level shоuld be 20 and leave it to the Court to decide.
According to Harris, the government’s permission to challenge the enhancement extended not only to sentencing, but also to a potential appeal.
Harris’s argument, however, is foreclosed by the plain and unmodified language contained in his plea agreement. Subject to a few limited exceptions that arе not applicable here, the plea agreement provides that Harris “g[a]ve[ ] up the right to appeal
any
sentence ... and the
manner
in which the sentence is determined.... ” (Emphasis added.) This waiver clearly еncompasses his challenge to the district court’s decision to apply the “crime of violence” enhancement at issue. Nothing in the record indicates that the government latеr modified the
waiver provision
when it allowed Harris to seek a reduced
Harris’s argument relies on the structure of the plea agreement. According to Harris, the parties might have structured the appeal waiver differently if he had not originally stipulated to a base-offense lеvel of seventeen. He contends that this is so because “the offense level used in the appeal waiver correspond^] with the offense level set forth in the guidelines stipulation.” Based on this relationship, Harris asserts that a modification of base-offense level necessarily modifies the appeal waiver. As we explained earlier, however, the appeal waiver provision is clear and unambiguous, and there is nothing in it suggesting that waiver was premised on the structure of the plea agreement. If the parties intended for this structure to be controlling, they would have manifested that intent in the original plea agreement or through a written amendment to that agreement. Further, the mere fact that Harris preserved an issue for argument before the
district
court does not prevent him from waiving that argument on
appeal.
It is not extraordinary for a defendant to enter into a plea agreement that permits him to make certain arguments at sentencing while simultaneously waiving the right to raise thе same arguments on appeal.
See, e.g., Watson,
IV.
We conclude that Harris waived his right to bring the instant appeal. We therefore do not reach the merits of his challenge to the district court’s decision to enhance his sentence pursuant to U.S.S.G. § 2K2.1(a)(4).
APPEAL DISMISSED.
