The Lancer L5AWM 300BLK Magazine has been specifically engineered for use with 300 Blackout ammunition, particularly 200+ grain subsonic cartridges. The updated internal geometry allows these longer heavier bullets to stack properly, which increases reliability when compared to a traditional .223/5.56 magazine.

The L5AWM is short for L5 Advanced Warfighter Magazine, as it was designed to be the ultimate AR-15 magazine for military, law enforcement, and competition. This .300 AAC Blackout magazine offers the reliability and endurance of traditional steel magazines, while still offering the weight and maneuverability of advanced, light polymer.

Its hardened steel lip assembly and anti-tilt follower promise excellent feeding into the firearm. Moving on, its advanced polymer body offers micro-stipple pyramids for excellent grip and control.

The outside of the magazine body is molded with 300 Blackout markings and the magazine ships with a contrasting flat dark earth base plate for easy visual identification.

Designed, tooled, manufactured, and assembled in the USA.

NOTE: These magazines have been specifically designed and optimized to alleviate the stacking and feeding issues commonly experienced when running 200+ grain subsonic .300BLK cartridges in standard .223/5.56 magazines. If you are shooting lightweight supersonic .300BLK ammunition (<150gr), we recommend using a standard .223/5.56 L5AWM magazine.

High capacity magazines are restricted in certain states: California, Colorado, Connecticut, District of Columbia, Illinois, Hawaii, Maryland, Massachusetts, New Jersey, New York , Vermont and Washington may be restricted in other municipalities. It is the customer’s responsibility to be aware of and abide by all applicable local laws.
