Strike Industries ARCAGB Collar Adjustable Gas Block .750" Black Steel

The Strike Industries ARCAGB Collar Adjustable Gas Block gives AR-15 and AR-308 platform builders a fast, repeatable way to tune gas flow without pulling the gas tube or removing the block from the rifle.

Built around a 0.750" journal, this clamp-on gas block installs with set screws. It is machined from steel with a black finish. The signature tool-less adjustment collar clicks between six preset positions: five pre-sized openings matched to common gas-restriction needs, plus a fully closed setting.

Rotating the collar between settings is quick enough to do on the range, making it easy to tune cycling for different setups. The design is well suited for toggling between suppressed and unsuppressed use, with a single twist returning the block to the exact same gas flow setting every time.

Designed for any standard 0.750" gas block journal, the ARCAGB ships as a single gas block ready for installation.
