Magpul PMAG 40 Round AR/M4 GEN M3, 5.56×45 Magazine (Black)


Product Description

The next-generation PMAG 40 GEN M3 is a 40-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.
Modified internal and external geometry also permits operation 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. 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. In addition, an included pop-off Impact/Dust Cover can optionally be used to minimize debris intrusion and protect against potential damage during storage and transit. Low profile ribs and new aggressive front and rear texture gives positive control of the GEN M3 in all environments, and a paint pen dot matrix has been added to the bottom panel of the body to allow easy marking by the end user for identification. 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.

Made in U.S.A.

    I received Gen M3 40’s the other day, and am impressed with them so far. I ran my Daniel Defense M4 hard with the new 40 rd and it was flawless! I was expecting a feed issue, but none to report. Good price, cool mag. Of course, your BI-POD need to a Harris with long extensions or similar…

    Very happy with these mags. Functions great, seem to be very good quality for being made of lightweight plastic. Price can’t be beat.
