The next-generation PMAG 30 GEN M3 Window is a 30-round 5.56x45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons that features a transparent window to allow rapid visual identification of approximate number of rounds remaining. 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.

Durable dual-side transparent windows allow for quick determination of approximate number of rounds remaining in the magazine. Utilizing a high visibility indicator coil on the spring and numerical markers on the magazine body, the MagLevel™ system provides positive verification without affecting the durability or reliability of the magazine.

  • Paint pen dot matrix panels on the bottom of the body to allow for identification marking

    Works perfectly.

    As most Magpul products, these magazines work perfectly. I've ran through a few hundred rounds and have had zero issues. I enjoy the window to be able to tell at quick glance roughly how many rounds I have left and enjoy the dust covers for storage. I'd recommend getting these but if you're not interested in the dust covers, save a bit and go with the previous generation.

    Gen3 Pmags

    Excellent quality magazines. Can’t go wrong. I find that the window mags are a little off on actual round count. Could just be the ones I received. Good enough for government work however.
