The next-generation Magpul 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 permit rapid visual identification of an 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 durability, strength, and credibility to exceed strict military performance specifications.

While the GEN M3 is optimized for Colt-spec AR15/M4 platforms, modified external and internal geometry also allows operation with a vast assortment of additional weapons like the HK® 416/MR556A1/M27 IAR, British SA-80, FN® SCAR™ MK 16/16S, and others.

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

Additionally, a redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, whereas an over-travel stop on the backbone can help to ensure the magazine will not over-insert on suitable weapons. Low profile ribs and new aggressive back and front feel gives favorable 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 permit easy marking by the end user for identification. The brand 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 much better grip with tight double and triple magazine components. An added pop-off Impact/Dust Cover can optionally be used to reduce debris intrusion and protect against potential harm to the top cartridge during storage and transit.

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