Magpul MAG556-BLK PMAG GEN M3 Window 223 Rem,5.56 NATO AR15, M4 30rd Detachable Magazine

Made in the USA, the next-generation PMAG 3 GEN M3 Window is a 3-round 5.56x45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons that features transparent windows to allow rapid visual identification of approximate number of rounds remaining. Similar to the MOE PMAG, the GEN M3 Window features a long-life USGI-spec stainless steel spring, four-way anti-tilt follower and constant-curve internal geometry for reliable feeding and simple tool-less disassembly to ease cleaning. 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-8, FN SCAR MK 16/16S and others.
