Cmmg Zeroed Adjustable Gas Block 750 Nitride 4140 Steel for Ar

The CMMG ZEROED Adjustable Gas Block offers precise gas system tuning for AR platforms, allowing you to dial in performance whether you're shooting suppressed or optimizing for your preferred ammunition. Crafted from 4140 steel with a durable nitride finish, this 0.750" gas block integrates a 20-position detent adjustment screw that ensures you won't overspend energy beating the rifle up or under-gas to the point of unreliable cycling. Its user-serviceable design features a sacrificial cleanout chamber that channels excess carbon away for easier maintenance, keeping your system cleaner and more functional over time. Included with the gas block is a 6" 3/32 hex wrench for easy adjustment and roll pin installation, making setup straightforward for a seamless fit on your rifle gas system. Ideal for shooters seeking consistent, tailor-made gas operation, the ZEROED block from CMMG delivers reliable cycling, enhanced efficiency, and longevity without sacrificing accuracy or control. This combination of robust materials, thoughtful design, and versatile adjustability makes it a practical upgrade for precision AR builds aiming for optimal performance across varied ammo and suppressor configurations.
