Made in the USA, the PMAG 30 AUS GEN M3 Window is a polymer magazine for Steyr AUG/F88/F90 compatible weapons that features transparent windows to allow rapid visual identification of approximate number of rounds remaining. It features a long-life USGI-spec stainless steel spring, four-way anti-tilt follower and constant-curve internal geometry for reliable feeding, and simple tool-less disassembly for easy cleaning. In addition, low profile ribs and aggressive front and rear texturing gives positive control 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 user for identification. The easy to disassemble GEN M3 flared floorplate aids in extraction and handling, and is slimmer than factory Steyr floorplates for better fit in magazine pouches.
