This is the GEN 2 Magpul PMAG Window 30 round magazine, chambered in .223 Remington / 5.56NATO.

This window PMAG is an excellent alternative to the mil-spec steel AR-15/M4 magazines, featuring a lightweight and sturdy polymer construction. Its internal components are just as solid, with an anti-tilt polymer follower and corrosion-resistant steel spring. Also, Magpul’s signature ribbed grip and flared floorplate provide better handling and easy extraction. 

 With dual transparent windows, round indicators, and high-vis indicators on the spring, very few magazine manufacturers can match the detail of Magpul’s MagLevel™ system.

If you’re looking for an upgrade to your mil-spec magazines, this windowed PMAG is a must-have. Try it out yourself – pick up a few today!
