A gas block jig would not save you from that problem. If the gas block can't line up then neither would the jig lol
yes it would because its going to let me drill the first dimple in the right spot, 100% aligned with the gas port.
Maybe you don't understand that is the import part to me, I can get another gas block or modify this one to slide on more. However if I drill dimple in the wrong spot, it will not matter what set screw gas block I try to use it wont align because Id have dimpled the barrel in the wrong spot.
If you still don't get it, the jig does not rely on simply sliding the jig on as far as you can and hope that is aligned. The jig has a centering pin or pointed set screw, that makes it align with the gas port on the barrel. it is a fool proof way of aligning that first dimple with the gas port hole in the barrel
Like so, pointed set screw aligns port hole, plastic tipped set screw locks it into place on the barrel. Then the 2 holes that are to be drilled/dimpled are on the other side of the jig
