Next Generation 30-Round Magazine Enhanced For Strength And Reliability

The Magpul PMAG M3 is a next-generation 30-round 5.56×45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons. Along with expanded feature set and compatibility, the GEN M3 incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability to exceed rigorous military performance specifications.

It has modified internal and external geometry that is compatible with a wide range of non-Colt-spec platforms such as the HK 416 and MR556A1, M27 IAR, British SA-80, FN SCAR MK 16/16S, and others.

Redesigned Bolt Catch Notch

The Magpul PMAG M3 has a redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, while an over-travel stop on the spine helps ensure the magazine will not over-insert on compatible weapons.

Similar to the MOE PMAG, the GEN M3 features a long-life stainless steel spring, four-way anti-tilt follower and constant-curve internal geometry for reliable feeding, and simple tool-less disassembly to ease cleaning.

Low Profile Ribs And Aggressive Front And Rear Texture

The new, easy to disassemble flared floorplate aids extraction and handling of the magazine while providing improved drop protection, but is slightly slimmer than before for better compatibility with tight double and triple magazine pouches.

The Magpul PMAG M3 has a paint pen dot matrix added at the bottom panel of the body to allow easy marking by the end user for identification.

Great mags.

Obviously Magpul's best release of the M-class yet. Really well built with slightly modified dimensions that seem to help the over all fluidity of the chambering process.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!
