Lancer L5AWM 300 Blackout 30-Round Magazine

Lancer L5AWM 300 Blackout Magazine

Lancer Systems engineered the L5AWM as a purpose-built magazine for 300 Blackout ammunition, particularly subsonic loads with 200-grain and heavier bullets. This isn't a repurposed 5.56 magazine—it's a thoughtfully designed tool built around the specific demands of the cartridge.

Design and Construction

The L5AWM represents a hybrid approach to magazine design:

• One-piece steel feed lip assembly wraps around the magazine body for consistent, reliable feeding
• Polymer construction provides weight savings and corrosion resistance compared to steel
• Aggressive surface texture ensures positive grip and control
• Constant curvature internal geometry with a non-tilting follower prevents bullet tilt and feeding failures

Performance Features

The magazine's internal geometry has been specifically optimized for longer, heavier 300 Blackout projectiles. This updated design allows proper bullet stacking, delivering superior reliability compared to standard .223/5.56 magazines when running subsonic ammunition.

Durability and Reliability

The L5AWM passes military chemical testing and resists corrosion and chemical degradation. The combination of steel and polymer materials provides the reliability of steel magazines with the durability and weight advantages of polymer construction.

Identification

The magazine body is molded with 300 Blackout markings, and each magazine ships with a contrasting Flat Dark Earth base plate for quick visual identification in the field or at the range.
