Overview

The Magpul PMAG 30 AR 300 B Gen M3 is a purpose-designed 30-round magazine optimized specifically for rifles chambered in .300 Blackout. It features an internal geometry tailored to accommodate the wide variety of bullet profiles and projectile weights used in .300 BLK cartridges while ensuring reliable feeding. Built from next-generation impact- and crush-resistant black polymer, the magazine includes a distinct rib design and smoother upper-half texture that provide a clear visual and tactile distinction from standard 5.56 magazines to prevent cross-loading. Additional features include aggressive front and rear texturing, a removable slim floor plate, a paint pen dot matrix for identification, and a self-lubricating follower.
