Made in the usa, the pmag 40 gen m3 is a polymer magazine for ar15/m4 compatible weapons. It features a long-life stainless steel spring, a four-way anti-tilt follower and constant-curve internal geometry for reliable feeding, and simple tool-less disassembly for easy cleaning. In addition, a redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, while an over-travel stop on the spine helps ensure the magazine will not over-insert on compatible weapons....
