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.
