MEMORANDUM**


2
Juan Cortez-Davilla ("Cortez") appeals his sentence under the United States Sentencing Guidelines ("U.S.S.G.") for conspiracy to possess with intent to distribute more than 500 grams of cocaine and possession with intent to distribute heroin, in violation of 21 U.S.C. §§ 846 & 841(a)(1), and possession with intent to distribute more than 500 grams of cocaine, in violation of 21 U.S.C. § 841(b)(1)(B).   Cortez contends that the district court erred by increasing his base offense level under U.S.S.G. § 2D1.1(b)(1).1  We have jurisdiction under 28 U.S.C. § 1291 and affirm.


3
Cortez argues that the evidence failed to show that he physically or constructively possessed the firearms discovered at the Juniper Court residence.   Nevertheless, Cortez failed to raise this issue in his written objections to the presentence report ("PSR") or before the district court at the sentencing hearing.   See United States v. Visman, 919 F.2d 1390, 1393-94 (9th Cir.1990), cert. denied, 112 S.Ct. 442 (1991).2  During the sentencing proceedings, the district court summarized the basis for the base offense level including the two-level firearm adjustment.   Cortez did not make any objections or comments concerning the firearm adjustment.   See id.   Accordingly, he waived his right to challenge the two-level increase.   See id. at 1394.

AFFIRMED.
