Adjustable Gas Blocks let you fine-tune your firearms gas system for smoother cycling and operation. Regulating the amount of gas used to cycle the action allows tuning the firearm's operation to a specific load and the use of low-mass bolt carriers, buffers, and springs to reduce felt recoil. This is critical to allow faster follow-up shots, target acquisition, and reliability.
The Davidson Defense Adjustable Gas Block is field adjustable. The operation is easy, simply turn the gas regulating screw in to lessen the amount of gas and out to add more gas, then use the brass set screw to lock the setting in place. The overall height of the gas block is 1.37†with left to right dimensions at .94†to fit under most hand guards and still have the customization of an adjustable gas block.
These gas blocks are Melonite Coated to reduce wear and corrosion for extended periods of fire, it also makes cleaning easier, as carbon build-up will not adhere to the non-reflective coated surface as much as it does on standard Phosphate finishes.
