Magpul Industries PMAG 30 AR 300 B GEN M3 (.300 BLK) 30-Round Magazines (10-Pack)
This set includes ten (10) Magpul PMAG 30 AR 300 B GEN M3 magazines, purpose-built for .300 AAC Blackout. The dedicated .300 BLK internal geometry supports a wide range of projectile weights and profiles for more consistent feeding than standard 5.56 magazines.
GEN M3 construction uses impact- and crush-resistant polymer, with a distinct rib and upper-body texture for quick visual/tactile identification. Features include a removable floorplate for maintenance and a paint-pen dot matrix for marking.
