Boasting a standard 30-round capacity, this aftermarket magazine features impact-, chemical-, and UV-resistant, translucent polymer construction for superior reliability in harsh and demanding environments. Further, the translucent body makes visual round counts quick and easy while this magazine's creep-resistant design ensures the feed lips and body won't spread, even when the magazine is fully loaded. An anti-tilt polymer follower and durable internal steel spring deliver ultra-reliable feeding. Plus, a built-in coupler allows you to connect multiple mags together in seconds with no tools. Further, this magazine features a ribbed gripping surface for positive handling and quick reloads in high-stress situations.
