Description
The Magpul PMAG Gen M3 is a 20-round polymer magazine designed specifically for AR-15 rifles chambered in 300 Blackout. It is intended for shooters who want a magazine built for this cartridge rather than one adapted from 5.56x45mm designs.
The magazine is black polymer and holds 20 rounds. A dedicated 300 Blackout design aims to improve feeding reliability across the range of projectile weights and shapes used with this cartridge. Its distinct rib pattern gives a visual and tactile difference from other PMAG magazines, helping shooters avoid loading 300 Blackout magazines into 5.56 rifles.
The PMAG Gen M3 fits AR-15 300 Blackout rifles.
