The Magpul PMAG M3 Window is a next-generation 30-round 5.56×45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons that features transparent windows to allow rapid visual identification of the approximate number of rounds remaining.

Along with expanded feature set and compatibility, the PMAG M3 Window incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability to exceed rigorous military performance specifications.

Magpul PMAG M3 30 Round Window - .223 / 5.56 NATO - MAG556

Modified Internal And External Geometry

The Magpul PMAG M3 Window has modified internal and external geometry that is applicable to 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. It has a redesigned bolt catch notch in the rear of the magazine that 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 PMAG M3 30-Round 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

The low profile ribs and new aggressive front and rear texture give positive control 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.

Dual-side Transparent Windows

Featuring durable dual-side transparent windows allow for quick determination of the 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.

Features:

  • Next-generation impact and crush resistant polymer construction
  • Modified dimensions allow for wider compatibility with non-Colt-spec’ STANAG 4179′ platforms
  • Constant-curve internal geometry for smooth feeding

  • Anti-glare translucent MagLevel windows on both sides of the body along with a painted indicator on the spring allow for easy determination of rounds remaining
  • Over-travel insertion stop on the spine
  • Ribbed gripping surface and new aggressive front and rear texture for positive magazine handling
  • Paint pen dot matrix panels on the bottom of the body to allow for identification marking
  • Flared floorplate aids magazine handling and disassembly yet is slim enough for use with many double and triple pouches
  • Made in the U.S.A.

Exactly as expected, fits 5.56 very smoothly, smaller than an average 30 round mag but its just right.

Thanks for sharing your feedback, Patrick. We're glad you're satisfied with your purchase. Cheers!
