Magpul MAG556-MCT Pmag GEN M3 Window AR15/M4 223 Rem/5.56x45mm 223 Rem/5.56 NATO 30 Round Polymer Medium Coyote Tan

Magpul MAG556-MCT MAG556MCT: The next-generation Pmag 30 GEN M3 Window is a 30-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-80, FN Scar MK 16/16S and others. Made in the USA.
