Whether you’re running a suppressor or tuning your AR for a specific load, the CMMG ZEROED Adjustable Gas Block lets you fine-tune your gas system with precision. Its 20-position detented adjustment screw helps you avoid both over-gassing that can cause excessive wear and under-gassing that prevents proper cycling, while the sacrificial cleanout chamber and user-serviceable design give carbon buildup a place to collect and make maintenance simple.
