Hilario Gonzalezr-Balderas, Sr., (Gonzalez), federal prisoner # 55110-079, appeals the district court’s denial of his 18 U.S.C. § 3582(c) motion to reduce his sentence based on retroactive application of Amendments 591 and 599 to the Sentencing Guidelines. He also argues that Amendment 505 should be applied in his case. However, Gonzalez did not raise this issue in the district court, and it will not be considered on appeal. See United States v. Smith, 915 F.2d 959, 964 (5th Cir. 1990). Moreover, this court has previously addressed this argument in United States v. Gonzalez-Balderas, 105 F.3d 981, 982 (5th Cir. 1997).

Gonzalez contends that Amendment 599 should be applied in his case. He argues that the firearm enhancement he received resulted in double counting under the provisions of Amendment 599. Because Gonzalez was convicted of offenses arising under 21 U.S.C. § 848 and 18 U.S.C. § 371, Amendment 599 is inapplicable to his case. See United States v. Dixon, 273 F.3d 636, 643-44 (5th Cir. 2001). His argument is without merit.

Gonzalez argues that Amendment 591 is retroactively applicable to his case. He asserts that his sentence was improperly calculated under U.S.S.G. § 2D1.1 rather than § 2D1.5. However, Gonzalez’s sen *173 tence was calculated by using § 2D1.5 to determine the base offense level, which referenced the drug quantity table of § 2D1.1. See Gonzalez-Balderas, 105 F.3d at 983. Additionally, Amendment 591 is irrelevant to the determination of base offense levels within the applicable offense guidelines section or to any consideration of relevant conduct. U.S.S.GApp. C, Amendment 591 (Nov. 2000).

The judgment of the district court is AFFIRMED.
