Far enough off that it was visibly canted. I noticed it before I even got a chance to zero it. I tried getting a good photo of it before I fixed it, but the photos always made it look straight. Two other people looked at it, though, and agreed it was off. When I disassembled it, the index notch in the upper was definitely off center.

After I opened the notch up a hair, the A-frame looks straight, but I had to go about 12-16 clicks right on the rear MBUS to get it zeroed. Enough to be annoying, but not enough to be a major problem.

Fortunately, the rifle runs well and seems to be fairly accurate from the minor testing I have done with it so far. I'm planning to be back on the range with it tomorrow to start running it at 100-300 yards.
Never argue with an idiot. They will drag you down to their level and beat you with experience.
