Out of stock



The Magpul PMAG 40 M3 is one of the highest capacity standard M4 or AR15 magazines available. They are used by civilian shooters and military alike, and can improve the reliablility of AR15 rifles by providing proper feeding. The M3 PMAG40 uses improved materials and manufacturing technology for enhanced strength and durability which exceeds milspec. The PMAG M3 features a modified self-leveling follower, constant curve internal geometry, and slimline  replaceable floorplate.

The PMAG M3 by Magpul has a redesigned shape for compatibility with non M4 spec rifles, including the HK416, MR556, SA80 or L85, FN SCAR-L, and more. Additionally, an over-insertion stop on the magazine prevents seating the mag too high, improving reliability. The floorplate is thinner to ease fit in tight double or triple magazine pouches. The PMAG40 M3 also features a checkered dot matrix section for marking ID on the magazines.
