Lancer Systems Magazine, L7 Advanced Warfighter, 308 Winchester, 762NATO, 25 Rounds, Clear, AR Rifles L7-25-CLR The L7AWM is a rifle magazine based on the AR-10/SR-25 pattern, made from a proprietary lightweight polymer with hardened steel feed lips that wrap entirely around the magazine.

A switchable drain lock in the floor plate is standard on all L7 models, allowing users to adapt the magazine for marine environments or extremely dusty conditions.
