The PMAG 30 AR 300 B GEN M3 is a purpose-designed magazine for rifleschambered in .300 Blackout. Since its inception, .300 Blackout shooters havehad to use a magazine designed for another cartridge, limiting its performanceand compatibility. One of the nice features of .300 Blackout is the compatibilitywith 5.56x45mm parts, but with the magazine it is a compromise to do so. Dueto the wide variety of projectile weights and shapes potentially decreasingoverall reliability, a dedicated .300 Blackout magazine was a logical step forthe PMAG line.
In addition to the performance gained by a dedicated mag, the PMAG 30AR 300 B also offers a safer way to feed your .300 BLK rifle. When using5.56 mags, the potential to chamber and fire a .300 BLK round in a 5.56 riflewith catastrophic results requires diligent ammunition management by theshooter. The PMAG 30 AR 300 Bs distinct rib design provides the shootera distinct visual and tactile difference from any other PMAG to mitigatedangerous cross-loading issues. Along with optimized .300 BLK performance,the PMAG 30 AR 300 B brings along all of the GEN M3 features such asour next-generation impact and crush resistant polymer, aggressive front andrear texture, an easily removable slim floor plate, a paint pen dot matrix formarking and identification, and a dust/impact cover.
