Magpul PMAG M3 300 Blackout Magazine, BLK, 20/5RD

300 BLK capabilities and reliability in a compact AR15 PMAG

When your rifle is chambered in 300 Blackout®, you need a magazine specifically built for that round. The PMAG 20 AR 300 B GEN M3 delivers the same consistent feeding across the wide range of 300 BLK projectile weights and profiles as our 30-round 300 BLK PMAG, but with a 20-round capacity and a more compact package for better maneuverability and prone use. 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.

Made in the USA.
