While shooting my Avenger I did a sight in but it was shooting low about 6" or so. This maxed out my elevation turret so I shimmed the rear ring.
I cut a shim from a business card which was about .014" thick and fit it to the lower rear ring. The next shot went about 6" high so I was able to adjust turret and finish sighting in.
I know it is not a good idea to shim a scope ring, but in this case I did not want to get tangled up with the Avenger Picatinny rail base. I was concerned about opening a can of worms. Note that all screws were tight when I received the Avenger and the barrel is not bent...(this thing is a tack driver.)
