From the manufacturer

Springfield Armory .300 Blk 30-Round Magazine Black 30. 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. 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'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 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. 30-round capacity Dedicated purpose-designed magazine for rifles chambered in 300 Blackout Optimized internal geometry accommodates the wide variety of bullet profiles used in 300 Blackout cartridges Carries forward the physical & performance features of the rest of the GEN M3 line Blackout is a registered trademark of Advanced Armament Corp.
