Yes. Although I cheated by looking up the sight height and radius rather than going back down to the shop to measure myself.
AR's are even worse with their high sight post. I think the tolerance spec for zeroing is something like 7 or 8 clicks from mechanical center. It's in a TM somewhere. I bought a brand new barrel from a shop on which they pinned a front site post for me. I went to zero and I needed 15 clicks. Tried to tell me at first it was normal so I did my own homework looking up the spec. I won't name the shop because he did make it right and exchange for one done more carefully.
