Magpul PMAG 30 Round AR 300 Blackout GEN M3 Magazine - OD Green

When your rifle is chambered in 300 Blackout®, you need a magazine specifically built for that round. The PMAG 30 AR 300 B GEN M3 is uniquely designed for 300 BLK to deliver more consistent feeding across the wide range of projectile weights and profiles. The distinct rib and unique upper texture also provide instant visual and tactile differentiation from 5.56 magazines to reduce cross-loading. With GEN M3 materials and engineering, it pairs impact- and crush-resistant polymer with proven feeding geometry for dedicated 300 BLK performance you can trust.
