I've known a lot of people including several gunsmiths that would use one piece of double stick tape on the bottom ring half of just one ring.
They would use to get the scope perfectly level and stuck in place so it wouldn't shift/cant when the rings were tightened down.
Of course most of these were also people who had never even heard of lapping scope rings HA!
