Product Description The Lancer Systems L5AWM 300 Blackout 30-Round Magazine is purpose-built for shooters who depend on heavy subsonic .300 Blackout ammunition, especially projectiles weighing 200 grains or more. Unlike a conventional .223/5.56 magazine, this model incorporates redesigned internal geometry that allows longer, heavier bullets to stack and feed with consistent reliability, eliminating the common feeding issues associated with standard AR magazines. The opaque black polymer body is engineered to endure impact, heat, and demanding field conditions, while a one-piece wrap-around steel feed lips construction delivers exceptional strength and extended service life. Prominent .300 Blackout markings on the body provide immediate caliber identification, and a contrasting Flat Dark Earth (FDE) floor plate makes it effortless to separate this specialized magazine from your standard 5.56 mags in any situation. Fully compatible with AR-15/M4 platforms and other 5.56-based systems, the L5AWM 300BLK is proudly manufactured in the USA.
