Magpul PMAG GEN M3 MAG800 Black 30rd for 300 Blackout AR-15

Made in the USA, the Magpul PMAG GEN M3 MAG800 is a purpose-designed magazine
for rifles. 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. Its 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
incorporates 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.
