The L7AWM is a professional-grade AR-10/SR-25 pattern magazine, built to handle the demands of military, law enforcement, and serious shooters. It features a rugged hybrid design combining a proprietary lightweight polymer body with hardened steel feed lips that wrap around the entire top of the magazine. This design maximizes stiffness and durability, preventing feed lip deformation and front-end dimpling during hard use or long-term storage.
