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.

I've got some failure to feed problems, but I don't think it's the mag; I believe it's the suppressor.

Yes, I recommend this product.
