Ar-15 300 Blk Pmag 30 Gen M3 Magazine - Pmag Ar 300 Gen M3 300blk 30rd For Ar15 Black 10/Pack

The PMAG 30 AR 300 B GEN M3 is a purpose-designed magazine for rifles chambered in .300 Blackout. Since its inception, .300 Blackout shooters have had to use a magazine designed for another cartridge, limiting its performance and compatibility. One of the nice features of .300 Blackout is the compatibility with 5.56x45mm parts, but with the magazine it is a compromise to do so. Due to the wide variety of projectile weights and shapes potentially decreasing overall reliability, a dedicated .300 Blackout magazine was a logical step for the PMAG line. In addition to the performance gained by a dedicated mag, the PMAG 30 AR 300 B also offers a safer way to feed your .300 BLK r Mfg: Magpul
