Cobalt Kinetics CKGB/NA750 Gas Block .750" Black Nitride Steel

The Cobalt Kinetics CKGB/NA750 is a .750" low-profile gas block designed for rifle barrels with a matching gas journal diameter. It is machined from steel and finished in Black Nitride for a hard, corrosion-resistant surface that stands up to hard use and harsh field conditions.

The gas block clamps to the barrel beneath the handguard and channels high-pressure gas from a fired round through the gas tube to cycle the action. Its low-profile design keeps the sight radius over the bore unobstructed and allows free-float handguards to sit cleanly along the barrel. The black nitride finish delivers a uniform dark appearance and added wear resistance without altering critical dimensions.

Built for straightforward installation on any rifle barrel with a .750" gas journal, this gas block is a direct replacement or upgrade component for builders and gunsmiths servicing or refreshing an existing gas system.
