Lancer L5AWM 300 BLK Magazine

The Lancer L5AWM 300 BLK magazine represents the premium tier of 300 Blackout magazine design, combining a translucent polymer body with hardened steel feed lips for exceptional durability and reliability. Specifically engineered for heavy subsonic 300 Blackout ammunition (200+ grain projectiles), this magazine features updated internal geometry that allows longer, heavier cartridges to stack properly, dramatically increasing feeding reliability compared to standard 5.56/.223 magazines.

The hybrid steel/polymer construction delivers the best of both worlds - steel feed lips that won't deform under stress or long-term loaded storage, combined with a lightweight polymer body that keeps overall weight manageable. The translucent smoke body allows instant visual verification of remaining rounds, while distinctive 300 Blackout markings and a contrasting flat dark earth floor plate enable easy visual identification to prevent dangerous caliber mix-ups.

Lancer Systems brings decades of military manufacturing experience to the L5AWM line, and the 300 BLK variant represents their specialized solution for this cartridge's unique feeding challenges. While lighter supersonic 300 Blackout loads may not require a dedicated magazine, shooters running heavy subsonic ammunition - particularly with suppressors - will appreciate the feeding reliability that purpose-built internal geometry provides.
