I picked one up the other day at an auction and gave her the TLC she needed to look and act like new once more. My question is at about 90 feet my hit point is about 1 1/2 inch to the left of the bulls-eye. The sight has up and down adjustment but no side to side and the front is fixed. Am I just stuck with it this way or can the rear sight be knocked to one side or the other to remedy this? Thanks, John.
