Magpul Industries PMAG M3, 300 Blackout, 30rd, Black, AR Rifles, Optimized Internal Geometry For 300 Blackout Bullets, Distinct Exterior Rib Design To Mitigate Crossloading 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 a magazine designed for another cartridge, limiting its ultimate 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 profiles potentially decreasing overall reliability, a dedicated 300 Blackout magazine was a logical step for the PMAG line. The performance gained by a dedicated mag, the PMAG 30 AR 300 B 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 provides the shooter a distinct visual and tactile difference from any other PMAG to mitigate 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 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.
