I bought a home built AR from a guy at a gun show once that had to have the rear sight all the way to the left to zero. When I lapped the upper, I had to take a lot of material off one side and when it cleaned up evenly all the way around, I put it back together and shot it. Then when zeroed, the rear sight was in the center.
I had a Colt HBar once that had to have the sight all the way over and I returned it to Colt. They did nothing and sent it back claiming it was "in spec".
I lap all of mine. Most are very close but they all get it anyway. I'm a believer.
