Magpul PMAG M3 Window 30 Round Magazine 5.56/223 

The latest from Magpul PMAG offering a window so that you can take a peek inside the life of your ammo. Compatible with both 223 rem and 556 NATO these mags are durable, light and reliable.

The next-generation PMAG 30 GEN M3 Window is a 30-round 556 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons that features transparent windows to allow rapid visual identification of approximately a number of rounds remaining.

Along with an 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.

Similar to the MOE® PMAG, the GEN M3 Window features a long-life USGl-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.

In addition, 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. Low profile ribs and new aggressive front and rear texture give 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. An included pop-off Impact/Dust Cover can optionally be used to minimize debris intrusion and protect against potential damage to the top cartridge during storage and transit.

Durable dual-side transparent windows allow for quick 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 body, the MagLevel® system provides positive verification without affecting the durability or reliability of the magazine.
