Made in the USA, the PMAG 30 AR 300 B GEN M3 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.

Because loading 300 in a 5.56 mag just doesn’t feel right. Buds was great with shipping. Fast and friendly.

bought these when trying to identify ftf and fte issues with my 300blkout, mags work well and are constructed to take a beating when ejected straight to the ground, however, be aware that when your msr gets hot the mags start to malfunction because of their polymer construction

Just like regular PMAGS, but for Blackout. PMAGS are my all-time favorite mags, and I've tried them all. Highly recommended.
