The PMAG is a lightweight 5.56 NATO, M-16 compatible magazine. It features an advanced impact resistant polymer construction, a pop-off Impact Cover for storage, and an easy to disassemble design with a flared floorplate for easy magazine extraction from pouches. The PMAG utilizes a resilient stainless steel spring for corrosion resistance. Our latest revision has been updated with a new body ribbing design which allows for better compatibility with aftermarket mag couplers, a new follower which provides even smoother loading with military stripper clips, and the Impact Cover can now be snapped onto the floor plate when not in use to prevent possible loss. These PMAG's have a 30 round capacity and are black in color.
