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 transparent windows to allow rapid visual identification of approximate number of rounds remaining. Along with expanded feature set and compatibility, the GEN M3 Window 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 Window 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 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.
Perfect mags from Magpul. Work fine in any AR.
Keep jamming my AR. At first thought that was ammo, so loaded now clip in it, same thing. Grabbed the original magazine and had no jams, so something is wrong with feeding from this magazine. Ended up in trash.
Like it. Feeds well, and no hang-ups. I expect that from Magpul. Get one if you can.
Item arrived earlier than expected and both the service and quality of the product exceeded expectations! My M&P15 will only run these magazines!
Bought these with my Windham AR15 purchase. Work flawless and it's cool to be able to use the sight window at times.
