To the proficient and knowledgeable, could one of you tell me how to measure the draw on an M1icon Carbine barrel installation? I took my carbine with a new barrel to a gunsmith and asked to have it installed. Also installing the front sight and the gas valve. When I got the gun back the barrel was still .025 from tick mark to tick mark. This also made the front sight out of alignment. I was told to just adjust the rear sight and it would be good to go. I was under the impression you lined-up the tick marks so everything was timed and square. I took the barrel back off the receiver and then hand tightened it and measured mark to mark. It measured .230, which is about 29.3 degrees. Can this be reinstalled to the marks. If I reinstall it the headspace will be reduced by .00044 if my calculation are correct.

Thank you,
