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 rifle. When using
5.56 mags, the potential to chamber and fire a 300 BLK round in a 5.56 rifle
with catastrophic results requires diligent ammunition management by the
shooter. The PMAG 30 AR 300 B’s distinct rib design provides the shooter
a distinct visual and tactile difference from any other PMAG to mitigate
dangerous cross-loading issues. Along with optimized 300 BLK 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.
