You need a very fine tip marker or scribe, and a long ruler or straight edge. Place the straight edge on top of the barrel aligning the gas tube slot on the upper with the center of the muzzle. The gas port should be in line with those two points. Mark a line running parallel to the straight edge an inch or two ahead of the gas pot hole. Then measure from the center of the hole in the bottom of the gas block to the end of the gas block where the gas tube enters. Mark the same distance along the center line you already marked on the barrel. Then you can align the gas tube home in the block with the center line and stop at the cross mark.
Of course some barrels have a lip for the blocks to stop at so you would only need to align the center line with the gas tube hole in the block.
What I described sounds a lot harder than it actually is to do. If it isn’t clear, reply back and I will see if I can clarify.
