Magpul PMAG GEN M3 Black Window 30rd for 5.56x45mm AR-15

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.
