Lancer L5AWM .300 Blackout 30-Round Magazine – Black with FDE Floorplate

The Lancer L5AWM .300 Blackout 30-Round Magazine is purpose-built for shooters running heavy subsonic .300 BLK loads. Engineered specifically for 200+ grain projectiles, this magazine features updated internal geometry that allows longer, heavier bullets to stack and feed reliably — a common pain point when using standard .223/5.56 magazines with subsonic .300 BLK ammunition.

The exterior is clearly marked with .300 Blackout identification and ships with a contrasting Flat Dark Earth (FDE) floorplate for instant visual differentiation from your standard AR magazines — a critical safety and operational advantage during range sessions or field use.

**Key Features:**
– Optimized internal geometry for 200+ grain subsonic .300 BLK ammunition
– 30-round capacity
– Distinctive .300 Blackout exterior markings
– Includes contrasting FDE floorplate for easy identification
– Translucent polymer body for round-count visibility
– Compatible with standard AR-15/M4 lower receivers

**Note:** This magazine is specifically designed for heavy subsonic .300 BLK loads (200+ grain). If you are shooting lightweight supersonic .300 BLK ammunition under 150 grains, Lancer recommends using a standard L5AWM .223/5.56 magazine instead.
