MEMORANDUM**

John William Baker appeals the sentence imposed following his guilty plea to possession of unregistered firearms, in violation of 26 U.S.C. § 5861(d). He claims that the district court erred by finding that he is a “prohibited person”1 within the meaning of U.S.S.G. § 2K2.1(a)(4)(B). We have jurisdiction pursuant to 28 U.S.C. § 1291, and we affirm.

At sentencing, the district court adopted the findings and recommendations of the Presentence Investigation Report (“PIR”). The PIR noted that Baker was subject to a restraining order at the time he committed the instant offense, and concluded that he was a “prohibited person” subject to a base offense level of twenty under U.S.S.G. § 2K2.1(a)(4)(B).2 Baker did not object to *763the PIR’s application of § 2K2.1(a)(4)(B). In fact, Baker confirmed that, aside from an objection to the PIR’s assessment of a criminal history point for a drug possession offense, there were no errors in the PIR’s application of the Sentencing Guidelines.

Because Baker failed to object below to the district court’s application of § 2K2.1(a)(4)(B), he has forfeited his right to appeal and is subject to this circuit’s discretionary plain error review. See United States v. Jimenez, 258 F.3d 1120, 1124 (9th Cir. 2001) (holding that, where a defendant failed to raise an objection before the district court, there was “an inadvertent forfeiture”; under such circumstances, the court of appeals “may review his claims for ‘plain error’ ”); United States v. Randall, 162 F.3d 557, 561 (9th Cir. 1998) (“Alleged sentencing errors are reviewed for plain error where the defendant has failed to object before the district court and therefore forfeited his right to appeal.”). Under this standard, Baker “must establish error that was clear or obvious and affected his substantial rights.... Even after that showing is made, [this court] will exercise discretion to correct an error only if it ‘seriously affeet[s] the fairness, integrity, or public reputation of judicial proceedings.’ ” United States v. Valencia Amezcua, 278 F.3d 901, 908 (9th Cir. 2002) (quoting United States v. Olano, 507 U.S. 725, 732, 113 S.Ct. 1770, 123 L.Ed.2d 508 (1993)). “Thus, more than plain error affecting substantive rights must exist for the court to reverse.” United States v. Olano, 62 F.3d 1180, 1188 (9th Cir. 1995) (on remand from, and citing, Olano, 507 U.S. at 736-37, 113 S.Ct. 1770).

Baker claims that the district court plainly erred because there was insufficient evidence3 in the PIR to establish that the restraining order met the requirements of 18 U.S.C. § 922(g)(8)(A)-(C). See supra note 1. However, even assuming, arguendo, that Baker is correct, we decline to notice the forfeited error. Baker does not argue, on appeal, that the protective order does not meet the requirements of § 922(g)(8)(A)-(C). Instead, he argues that the Government did not provide sufficient evidence. However, the only reason the Government failed to do so is because Baker confirmed the accuracy of the PIR and did not contest the application of U.S.S.G. § 2K2.1(a)(4)(B). In fact, the Government specifically stated in its Guilty Plea Memorandum that it could prove beyond a reasonable doubt all of § 922(g)(8)(A)-(C)’s requirements. Under these circumstances, the district court’s alleged error does not “seriously affect the fairness, integrity, or public reputation of judicial proceedings.”

AFFIRMED.
