This is the Magpul PMAG GEN M3 AR-15 .300 Blackout 30-round magazine. 

Trusted by military personnel, law enforcement, and civilians all over the world, the Magpul PMAG continues to be one of the most popular magazines on the market. 

You no longer need to use 5.56x45mm magazines to feed your .300 Blackout rifle, as these PMAGS are purpose-designed. Of course, they are constructed out of the same crush-resistant polymer as you’d expect from a PMAG and feature an anti-tilt polymer follower to keep them running smoothly. 

All of the PMAG Gen M3 features are included, such as front and rear texturing, a paint-pen dot matrix, and an easily removable slim floor plate. 

PMAGs will rise to the occasion, whether being used in a SHTF scenario or a laid-back afternoon range session. Best of all, they are made right here in the USA!

Mitigate potentially dangerous cross-loading issues and pick up a few of these .300 Blackout PMAGs today!

Note: As of 11/1/23, these magazines no longer include a pop-off dust cover. However, you can purchase them here.
