Made in the USA, the PMAG 10 GEN M3 is a 10-round 5.56×45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons. The PMAG features a long-life stainless steel spring, four-way anti-tilt follower for reliable feeding and an easy to disassemble flared floorplate to aid extraction and handling of the magazine while providing improved drop protection. 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. An included pop off Impact/Dust Cover can be used to minimize debris intrusion and protect against potential damage to the top cartridge during storage and transit. While the GEN M3 is optimized for Colt-spec AR15/M4 platforms, modified internal and external geometry also permits operation with a range of additional weapons such as the HK 416/MR556A1/M27 IAR, British SA-80, FN SCAR MK 16/16S and others.
