Description
Made in the USA, the Magpul PMAG Gen M3 Window is a polymer detachable magazine designed for AR-15/M4-compatible weapons. It includes transparent viewing windows that provide rapid visual identification of approximate remaining rounds and a redesigned bolt catch notch for increased clearance. An over-travel stop on the spine helps prevent over-insertion on compatible weapons, while low-profile ribs and an updated textured surface aid positive control in varied conditions.
