That helps. I would lean towards the most likely culprit being that they mismatched the rings at the factory. With the quality of both Sako and Swarovski it would be hard to believe that the receiver milling was so far off or that the scope was misassembled.I agree and would do the same. Good luck!
The rings should be the same as they come as a set but the mount are slightly different, one of them has a locating pin like as shown in the video ...
