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. It is melonite coated to reduce wear and corrosion for extended periods of fire. NOTE: This model does not include a gas tube roll pin.
