MAGPUL – PMAG AR/M4

Magpul PMAG AR/M4 GEN M3 Magazines (30-Round, 40-Round & Window) – 5.56 NATO / .223

The Magpul PMAG AR/M4 GEN M3 magazine is a next-generation polymer magazine designed for AR15, M4, and STANAG-compatible rifles chambered in 5.56×45 NATO / .223 Remington. Built with advanced materials and improved internal geometry, GEN M3 PMAGs deliver exceptional durability, reliable feeding performance, and military-grade strength.

Optimized for Colt-spec AR15/M4 platforms, the GEN M3 series is also compatible with a wide range of rifles including HK416, MR556A1, M27 IAR, FN SCAR-16/16S, SA-80, and IWI Tavor.

Each magazine features a USGI-spec stainless steel spring, four-way anti-tilt follower, constant-curve internal geometry, and tool-less disassembly for easy maintenance. The redesigned bolt-catch notch and over-travel stop help prevent over-insertion while improving reliability.

The textured grip surface, paint-pen dot matrix for identification, and slim flared floorplate enhance handling and durability in demanding environments.

Made in the USA.
