There was no big gap top or bottom.Reloader7RM when I did my search wish that would have come up I would have lapped them.As long as I leave then on this gun where they are you can't see it.But it still pisses me off.I really don't think I did anything wrong.The scope came off another gun mounted with Leupold Rifleman rings no marks none.I wanted to put a little nicer mounts on this gun.
