This is the 3rd generation M3 20 round PMAG in .300 BLK (300 AAC Blackout).

Magpul has introduced a dedicated magazine with geometry tailored for popular 300 BLK loads for improved feed, rather than shooters having to use 5.56mm magazines which can run into issues feeding loads with heavy profile bullets.

Usual bomb proof MAGPUL Gen 3 build quality, easy to strip and with a clip on dust cover as standard. The third generation design features feed lip and spine reinforcements and an improved 4 way anti-tilt follower.

Compatible with all AR-15 and STANAG rifles chambered for 300 BLK.
