Magpul PMAG M3 300 BLK 30RD - Black - MAG800-BLK

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 magazines designed for another cartridge, which limits its ultimate performance and compatibility. One of the notable features of the 300 Blackout is its compatibility with 5.56x45mm parts; however, this comes at the cost of a compromise with magazine capacity. Due to the wide variety of projectile weights and profiles, which could potentially decrease 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 Blackout rifle. When using 5.56x45mm mags, the potential to chamber and fire a 300 Blackout round in a 5.56x45mm rifle with catastrophic results requires diligent ammunition management by the shooter. The PMAG 30 AR 300 B’s distinct rib design and smoother upper-half texture provide the shooter with a distinct visual and tactile difference from any other PMAG, mitigating dangerous cross-loading issues. Along with optimized 300 Blackout performance, the PMAG 30 AR 300 B brings along all of the GEN M3 features, such as our next-generation impact and crush-resistant polymer, aggressive front and rear texture, an easily removable slim floor plate, a paint pen dot matrix for marking and identification, and a dust/impact cover.
