Gas port is .295" from the edge.That is the spec.I have seen a gas block very nicely machined pretty and all that was .250 from the edge.Customer supplied it.I do machine a dimple exactly 180 degrees from the gas port for the screw on my barrels.That makes it easy for block alignment.The gas hole going up in the block is usually .125" so you have some slack.
