Made in the USA, the next-generation PMAG 40 GEN M3 is a 40-round 5.56x45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons. The PMAG 40 GEN M3 features a long-life stainless steel spring, four-way anti-tilt follower and constant-curve internal geometry for reliable feeding and simple tool-less disassembly to ease cleaning. A 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. Low profile ribs and new aggressive front and rear texture gives positive control of the GEN M3 in all environments and a paint pen dot matrix has been added to the bottom panel of the body to allow easy marking by the end user for identification. The easy to disassemble flared floorplate aids extraction and handling of the magazine while providing improved drop protection, but is slightly slimmer than for better compatibility with tight double and triple magazine pouches. 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.
