The next-generation PMAG 30 AR/M4 GEN M3 is a 30-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 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 weapons such as the HK 416/MR556A1/M27 IAR, British SA-80, FN SCAR MK 16/16S, and others.
