OK, it may be more complicated. You are dealing with "barrel indexing" and anything 13 clicks or less off is considered OK. Yep, 13 clicks is considered acceptable. Messing with the bbl's indexing can throw head spacing off so unless you are outside that much or more, just adjust the sight for zero and forget new gas blocks, etc.

since yours is 14 clicks off (IF you are sure of that FROM ABSOLUTE SIGHT CENTER) send it in for warranty correction NOT a job for a novice gunsmithing owner.
