The L5AWM 300BLK 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 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.

About the L5AWM:
Lancer set out to design a better 5.56 magazine; one with the reliability of steel, durability of polymer and weight of aluminum – the L5AWM. The magazine design includes a one-piece, wrap-around steel feed lip assembly and an aggressive surface texture to create the ultimate hybrid magazine tough enough for military, LE and commercial use. The L5AWM is compatible with modern weapon systems, including M4/M16/AR15, SCAR16, HK416, ARX160, SIG556, ARC, IWI Tavor, SA80, and many more.

Lancer magazines in the 20 round size are perfect for 300 AAC BLK pistols. They perform flawlessly with the heavy bullets. Great design with metal feed lips.
Also the tan base for instant ID is a plus. These are the only magazines I use in my .300 AAC BLACKOUTS.

These are the only mags I run in my 300BLK and I was so glad to find them here at Black Label Armory. The folks at BLA are great to deal with and they have some pretty good deals to boot.
