Engineered to feed heavy subsonic .300BLK loads with the benefits of steel reinforced feed lips.
Specifically engineered for use with heavy subsonic .300 Blackout ammunition (200+ grain), the Lancer L5AWM® 300BLK magazine features an updated internal geometry which allows longer heavier cartridges to stack properly, increasing feeding reliability when compared to a traditional .223/5.56 magazine. The outside of the mag body is molded with distinctive .300 Blackout markings, and the magazine ships with a contrasting flat dark earth floor plate for easy visual identification.
If you are using .300BLK loads 150 GR or lighter, Lancer recommends using standard L5AWM magazines.
