I just bought seven of these. I love the M-16/M-4 versions and have patiently waited for an offering for the Kalashnikov. They feature a removable floorplate, constant curve geometry, and high-reliability/low-friction follower for the performance you expect from a PMAG. Upon initial inspection they appear to be quality gear, however I am a little suspect that the magazine locking tab is not steel. This is always a weak point on polymer Kalashnikov magazines. According to the internet rumor mill the next generation of the magazine will have steel reinforced feed lips and tab.
