CMMG Zeroed Adjustable Gas Block .750" ID

The CMMG Zeroed Adjustable Gas Block .750" ID is designed for professional users who require precise control over their AR gas system. This component allows fine tuning of gas flow to optimize firearm cycling, especially when using suppressed ammunition or varying ammo types.

Its 20-position detent adjustment screw provides incremental control to prevent excessive gas pressure that can cause wear or insufficient gas that may fail to cycle the firearm reliably. The gas block features a sacrificial cleanout chamber that collects excess carbon, facilitating maintenance and ensuring consistent performance.

Included with the gas block is a 6" 3/32 hex wrench for adjusting gas settings and installing the roll pin.
