Here's an update....

I tried sighting it in with two business card widths under the back ring. Shot low, and with adjusting all the way to the top, hit just beneath the bottom of the paper. Then I put three in there and hit paper 4 inches low. So I tried to put 4 in there, but only one ring screw threaded on somewhat and the other was too short. When I shot, it hit slightly HIGH, but the one screw came out. Now I plan to get longer screws for the quick fix, but I want those POS align rings eventually. Nobody carries them near me and with shotgun season fast approaching, I'd rather get the longer screws and make sure Iam on and go with it until I have time to get a better fix in place.
