This is a bulk 3-pack of the Magpul PMAG GEN M3 AR-15 20 round magazine in .300 AAC Blackout.

More compact than 30 round magazines, the PMAG 20 features increased maneuverability and creates a more concealable package for use in small format firearms.

Along with optimized .300AAC BLK performance, the 20 round PMAG incorporates all of the GEN M3 features, such as next-generation impact and crush resistant polymer, aggressive texturing, an easily removable floor plate, and a paint pen dot matrix for marking and identification.
