Kaw Valley Precision AR-15 Adjustable Gas Block .750 Features The Kaw Valley Precision AR-15 Adjustable Gas Block .750 is machined from domestic USA steel giving it the strength needed to withstand the repeated heat and pressure of firing. A black oxide finish is applied over the steel body adding a layer of corrosion resistance while keeping a clean low-profile appearance on the rifle. The gas block is designed to fit a .750 gas journal matching one of the most common barrel diameters used on AR-15 builds. This steel construction and precise fit make it a durable option for both range use and harder duty cycles. Adjustability is built into the design through a 10-32 set screw with .400 spacing allowing a builder to fine tune the amount of gas sent back into the system. A 3/32 Allen wrench is used to make these adjustments giving shooters a simple way to dial in reliable cycling with suppressors subsonic ammunition or varying barrel lengths. This level of control helps reduce excess bolt velocity and felt recoil once the system is properly tuned. The Kaw Valley Precision AR-15 Adjustable Gas Block .750 gives builders a straightforward American-made way to fine tune their rifle s gas system for smoother more reliable operation.
