Lancer L5AWM .300 Blackout 30-Round Magazine – Opaque Black

Engineered specifically for heavy subsonic .300 Blackout ammunition, the Lancer L5AWM 300BLK 30-Round Magazine delivers the feeding reliability that standard .223/5.56 magazines simply can’t match. With updated internal geometry designed to properly stack and feed longer, heavier projectiles — including 200+ grain bullets — this magazine is an essential upgrade for suppressed builds and subsonic shooting applications.

The opaque black polymer body is clearly marked with .300 Blackout identification, eliminating any risk of mixing up calibers in the field or at the range. It ships with a contrasting flat dark earth floor plate for quick visual differentiation. Whether you’re running a dedicated .300 BLK AR-15 or a suppressed SBR build, the Lancer L5AWM ensures your heavy subsonic loads feed smoothly and consistently every time.

At just $19.99, this is an affordable, purpose-built solution from one of the most trusted names in polymer magazines. Order online today for fast shipping, or stop by Deep Roots Rifle Co in Eustis, Florida, where our knowledgeable staff can help you find exactly what your build needs.
