Magpul MAG556BLK PMAG GEN M3 30rd Detachable wCapacity Window 223 Rem5.56x45mm NATO Fits AR15M16M4 Black Polymer

Made in the USA the PMAG 30 GEN M3 Window is a polymer magazine for AR15M4 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 overtravel stop on the spine helps ensure the magazine will not overinsert 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. NOTE This item is also compatible with HK 416MR556A1M27 IAR British SA80 FN SCARN MK 1616S and others.
