Lancer L5AWM .300 Blackout 20-Rd Opaque Black AR-15 Magazine

The Lancer L5AWM (L5 Advanced Warfighter Magazine) is a 20-round AR-15 magazine purpose-built and geometry-optimized for .300 AAC Blackout. Lancer engineers took the proven L5AWM 5.56x45mm NATO platform and retuned the internal geometry specifically for heavy subsonic .300 Blackout loads - particularly projectiles in the 200+ grain range - so the magazine feeds and functions reliably with the slower, heavier projectiles that define the cartridge.

The L5AWM pairs a durable polymer body with hardened steel feed lips and a non-tilt follower for smooth, consistent feeding and long service life. The Opaque Black body is dimensionally compatible with any standard AR-15 lower receiver chambered in .300 AAC Blackout.

Whether you run a suppressed SBR for home defense, a hog-hunting rifle, or a tactical platform, the Lancer L5AWM .300 Blackout magazine delivers the reliability and weight savings serious shooters expect from Lancer's Advanced Warfighter line.
