Lancer L5AWM 300 Blackout 20-Rd Translucent Smoke AR-15 Magazine

The Lancer L5AWM is a purpose-built 20-round detachable magazine chambered for .300 AAC Blackout and engineered specifically around heavy subsonic loads with 200+ grain projectiles. The translucent Smoke polymer body gives instant visual confirmation of round count at a glance, while the magazine pairs its constant-curve internal geometry with hardened steel feed lips, a steel-reinforced magazine catch, a stainless steel spring, and a non-tilt follower to keep rounds cycling reliably in semi-auto AR-pattern rifles.

Built around an impact-resistant polymer shell, the L5AWM drops into a standard AR-15 lower receiver and is sized to clear the wide variety of supersonic and subsonic 300 Blackout ammunition on the market — from supersonic rifle rounds to the heavy, quiet subsonic loads the platform was designed around. The translucent Smoke finish lets the shooter spot a low round count at a glance on the range, in a vehicle, or at a nightstand.

Every L5AWM 300BLK magazine is a factory Lancer production part designed, built, and assembled as a dedicated 20-round magazine for AR-15 platform rifles chambered in .300 AAC Blackout, making it a versatile upgrade or replacement for any 300 Blackout AR build.
