Check the inside of the rings before you tighten them down. I've had older Weaver rings with slight internal protrusions that seemed to have came from when they punched the holes in the steel portion of the ring. I have actually had some rings make slight divets in the sides of Weaver scopes when tightened down. A little gentle sanding on the inside at that point was enough to knock the protrusions down. That followed up with a some cold blue and all was good to go. I haven't noticed this issue on all Weaver rings but I have with enough to always make me look before jumping.
