Magpul MAG556BLK PMAG GEN M3 30rd Detachable w/Capacity Window 223 Rem/5.56x45mm NATO Fits AR-15/M16/M4 Black Polymer

Made in the USA, the PMAG 30 GEN M3 Window is a polymer magazine for AR15/M4 compatible weapons that features transparent windows to allow rapid visual identification of approximate number of rounds remaining. 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 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. An included pop-off impact/dust cover can optionally be used to minimize debris ntrusion and protect against potential damage to the top cartridge during storage and transit. NOTE: This item is also compatible with HK 416/MR556A1/M27 IAR, British SA-80, FN SCARN MK 16/16S, and others.

I was a bit apprehensive with a site name like GunStuff TV, but after some research I learned that they are legit. I got a screaming good deal on PMAG M3 Window mags and free shipping, and the order shipped in 2 business days with FedEx home delivery. I am very impressed and will keep this site in mind for future purchases. The M3 Window PMAGS are the best magazine in the world, and I couldn’t pass up such a good deal. Unfortunately the price on them has now increased, but if they ever run a deal again and have free shipping too, then I’ll definitely be buying more!
