Magpul PMAG 30 Round AR GEN M3, 300 Blackout

The PMAG 30 AR 300 B GEN M3 is a purpose-designed magazine for rifles chambered in 300 Blackout® (300 BLK). Since its inception, 300 BLK shooters have had to use a magazine designed for another cartridge, limiting its ultimate performance and compatibility. Along with optimized 300 Blackout performance, the PMAG 30 AR 300 B incorporates all of the GEN M3 features such as Magoul’s next-generation impact and crush resistant polymer, aggressive front and rear texture, an easily removable slim floor plate, and a paint pen dot matrix for marking and identification.
