Product Description
The Magpul PMAG 40 AR/M4 Gen M3 is a next-generation 40-round polymer magazine designed for 5.56x45 NATO (.223 Remington) in AR15/M4-compatible firearms. Built with advanced material technology and updated manufacturing processes, it is engineered for enhanced strength, durability, and reliable feeding to meet demanding performance requirements. While optimized for Colt-spec AR15/M4 platforms, its modified internal and external geometry helps broaden compatibility with a range of other weapons, including the HK 416/MR556A1/M27 IAR, British SA-80, FN SCAR MK 16/16S, and more.

- Constant-curve internal geometry designed to support smooth, consistent feeding
- Anti-tilt, self-lubricating follower helps enhance feeding reliability
