I picked up a kokopelli accurizing kit. I used the alignment rods and played with the configuration of the rings and they would point off in the same direction, no matter the configuration every time. The rings themselves are aligned to each other fine.

I installed the rings on an ar flat top receiver and used the rods. Center rod pointed perfectly down the barrel. This is why I think it's either the base or holes.
