The Magpul PMAG® 30 AR/M4 GEN M3™ Window is the benchmark by which all AR-15 magazines are measured. Trusted by military personnel, law enforcement officers, competitive shooters, and firearm enthusiasts worldwide, the PMAG GEN M3 Window combines legendary reliability, advanced polymer construction, and integrated round-count visibility into one of the most durable rifle magazines available.

Designed for AR-15, M4, and M16 platforms, the PMAG 30 GEN M3 Window features MagLevel® transparent windows with a high-visibility indicator coil, allowing shooters to instantly verify ammunition status without removing the magazine from the firearm. Clear round-count markings provide continuous visual feedback, helping users maintain awareness during training, competition, defensive use, and professional applications.

The constant-curve internal geometry and self-lubricating anti-tilt follower promote exceptionally reliable feeding under adverse conditions. Combined with a corrosion-resistant stainless-steel spring and crush-resistant polymer body, the PMAG GEN M3 Window is engineered to perform in extreme environments ranging from desert heat to freezing temperatures.

Additional enhancements include reinforced feed lips, an over-insertion stop for improved compatibility across weapon systems, aggressive texturing for positive handling, paint pen marking panels for magazine identification, and a slim-profile removable floorplate for simplified maintenance.

Extensively tested in mud, sand, dust, rain, extreme heat, and freezing temperatures, the PMAG GEN M3 Window continues to set the industry standard for AR-15 magazine performance.
