The Lancer L5 Advanced Warfighter Magazine was CMMG’s choice for the perfect .458 SOCOM mag. CMMG modified the feed lips of the magazine without machining or weakening them, so that they accept nearly every type of 458 SOCOM ammo. Laser Engraved with 458 SOCOM.
NOTE:  The magazine has been modified to function properly with 10rds of .458 SOCOM, but will physically hold 11rds if forced.  As such we will not ship these magazines to any state where magazine capacity is restricted to 10 rounds or less.
