The next-generation PMAG 30 AR/M4 GEN M3 is a 30-round polymer magazine for AR15/M4 compatible firearms chambered in 5.56×45 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 that exceed rigorous military performance specifications. 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 firearms 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 30 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 platforms. 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.
