After extensive testing of magazines on the market for 458 SOCOM the Lancer L5 Advanced Warfighter Magazine was the top choice due to the polymer body and steel feed lips. The CMMG-modified Lancer L5-AWM takes this top of the line magazine and perfects it for the wide range of 458 SOCOM on the market, by modifying the way the feed lips hold the 458 SOCOM without machining or weakening the steel feed lips. Laser Engraved 458 SOCOM. 10 round capacity.

NOTE:  This magazine is a modified 30rd 5.56 magazine and as such can still hold 30rds of 5.56 ammo. Due to an RCMP bulletin, these magazines are classified as "dual caliber" so they will need to be blocked to 5 rounds of 5.56. There will be a rivet set at the 5.56 position but there will also be a rivet set at the .458 Socom.
