I will verify alignment
pretty sure its GTG though for that.
JP Gas Blocks call for .025 gap between the shoulder on the barrel and gas block as Frank was saying. You should measure from the shoulder to the center of the gas hole on the barrel then measure the gas block edge to center of the gas hole to be positive. I have one barrel .025 and on another barrel .010. Just measure to be sure.
