Lancer Systems L5AWM 10rd .300 Blackout Magazine

The Lancer Systems L5AWM magazine is purpose-built for .300 AAC Blackout use and is optimized to feed longer, heavier subsonic projectiles reliably. Updated internal geometry accommodates 200+ grain rounds to reduce stacking and feeding issues that can occur when using standard .223/5.56 magazines. The body is molded in translucent smoke for round visibility and ships with a contrasting FDE floor plate for quick identification.
