KAK Industry Adjustable Gas Block Features The KAK Industry Adjustable Gas Block offers 20 distinct positions of adjustability giving shooters precise control over how much gas is diverted to cycle the action. This level of adjustability is particularly valuable when running a suppressor which typically increases back pressure and over-gasses a rifle built around a fixed gas block. A tactile adjustment screw with detent lets shooters feel and count clicks as they dial in the right setting making the process repeatable without needing to mark or measure each time. Reducing gas flow to the minimum needed for reliable cycling also reduces felt recoil wear on internal components and the amount of gas blown back into the shooter s face. Built from steel for a .750 gas block journal the block is finished in a protective phosphate coating with a Black Nitride surface treatment for additional corrosion resistance and wear durability. KAK Industry includes knurled set screws and a gas tube roll pin with the block covering the hardware needed for a complete installation. KAK Industry was founded in 2011 to fill a gap in the market for quality American-made AR-15 components at accessible prices a mission reflected in this block s build quality. The KAK Industry Adjustable Gas Block is available for sale at GrabAGun for AR-15 owners looking to fine-tune their rifle s gas system.
