The PMAG 30 AUS GEN M3 Window is a 30-round 5.56x45 NATO polymer magazine for Steyr(R) AUG/F88/F90 compatible weapons that features transparent windows to allow rapid visual identification of approximate number of rounds remaining. Similar to the GEN M3 PMAG for the AR15/M4, the PMAG 30 AUS 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 to ease cleaning. In addition, low profile ribs and aggressive front and rear texture 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 end 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.
