Lancer Systems builds the L7AWM (part no. L720BLK) for AR-10-pattern rifles chambered in .308 Winchester, 6.5 Creedmoor, or 7.62x51mm NATO, holding 20 rounds in a lightweight polymer body with steel feed lips that wrap completely around the magazine to maximize stiffness and reliability while preventing dimpling at the front. A switchable drain lock in the floor plate lets shooters configure the magazine for water-borne or extreme dust conditions, a genuine field-use feature rather than a cosmetic one. It’s designed to work across multiple AR-10-pattern weapon systems including the SR25, DPMS 308, SIG 716, LMT, LM308, POF P308, and Smith & Wesson M&P10, though it is not compatible with the Armalite AR-10B, Springfield Armory M1A, Rock River Arms LAR-8, FN SCAR 17S, PTR-91, HK417, or other rifles using M14, FN FAL, or HK 91/G3 patterned magazines. For Lancer Systems owners running a supported AR-10-pattern rifle, this AR magazine is a durable, field-ready option.
