Got the rings on tight last night. Checked the rail and it was good and tight so I just really cranked down on the base screws. I was fearful that they might snap off but I would tighten them just a litt more each time and check for wiggle. I think the screws were too long and I had to come all the way through the knob/nut and then some. I think the knob/nut wan't drilled all the way through. Should be good to go now though. Will check again after shooting a bit.

Thanks for the help.
