Kaw Valley Precision Adjustable Gas Block Features The Kaw Valley Precision Adjustable Gas Block gives AR-15 owners direct control over the amount of gas routed back into the action which is especially valuable when running a suppressor or experimenting with different ammunition. Dialing the gas flow down reduces felt recoil and bolt carrier velocity extending the life of internal components and softening the cycling of the rifle. Machined from USA steel the block is built to handle the heat and pressure of repeated firing without deforming or wearing prematurely. The black oxide finish adds a layer of corrosion resistance while keeping a low-profile factory-style appearance. Adjustment is handled through a 10-32 set screw with .400 inch spacing accessed with a 3/32 inch Allen wrench for quick and repeatable tuning. This simple mechanical design keeps the block easy to service in the field or at the bench without specialized tools. Sized at .625 inch it fits common AR-15 barrel gas block diameters for a direct drop-in installation. Shooters running suppressors short-barreled builds or simply chasing a smoother-cycling rifle will find this gas block a practical and durable upgrade.
