KAK Industry Adjustable Gas Block .750" Low Profile AR-15 - Black Nitride

The KAK Industry Adjustable Gas Block is a precision low-profile gas block designed for AR-15 rifles with a .750" gas block journal. Machined from 4140 steel and finished in durable black nitride, this gas block gives the shooter full control over the rifle's gas system for reliable cycling across a wide range of ammunition loads and suppressor setups.

Featuring 20-position adjustability, the KAK gas block uses a tactile adjustment screw with a positive detent to hold settings in place under fire. Tuning is done in quarter-turn increments - turn the screw clockwise to restrict gas flow, counter-clockwise to open it up. The low-profile design sits cleanly under most free-float handguards without interference.

A 7" adjustment wrench is included so the set screw can be reached once the block is installed beneath the handguard. The black nitride finish provides excellent wear and corrosion resistance for long service life in the field. Whether tuning for suppressed shooting, light bullets, or heavier reciprocating mass, the KAK Industry adjustable gas block is a straightforward, effective upgrade for any AR-15 build.
