Magpul PMAG AR M4 Magazine with Shield Arms Mag Extension

Made in the USA, the Magpul PMAG AR M4 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 in magazine extraction and handling while providing improved drop protection. It is also 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 intrusion 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.
