Magpul PMAG 40 AR/M4 GEN M3 Magazine (MAG233) is a next-generation 40-round polymer magazine for AR15/M4 compatible weapons chambered in 5.56x45 NATO / .223 Remington. Along with expanded feature set and compatibility, the GEN M3 incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability.
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.
Similar to the MOE® PMAG, the GEN M3 features a long-life USGI-spec stainless steel spring for commonality, a four-way anti-tilt follower, constant-curve internal geometry for reliable feeding, and simple tool-less disassembly for easy cleaning.The PMAG 40 GEN M3 also includes a redesigned bolt catch notch in the rear of the magazine that 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 give 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 for identification. The new, easy to disassemble flared floorplate aids extraction and handling of the magazine while providing improved drop protection, but is slightly slimmer than before for better compatibility with tight double and triple magazine pouches. An included pop-off impact / dust cover can optionally be used to minimize debris intrusion and protect against potential damage to the top cartridge during storage and transit.
