If you buy a quality 1pc base and quality rings you shouldn't need to lap the rings. The base must set completely flat on your action,if it doesn't,then the base will need to be bedded to the action.
Rings like the Burris Signature Zee rings are great rings to use. They have plastic inserts that allow any small alignment issues be corrected without damaging the scope tube,and they also will never leave ring marks on the scope.
All of my high end 34mm and 40mm tubed scopes set in ARC M10 rings. They are the best rings made,IMO. They aren't cheap,$180 a set,but that's cheap insurance when you're mounting a $1500 - $4000 scope on top of a rifle.
I totally agree, see post #3!Rings like the Burris Signature Zee rings are great rings to use. They have plastic inserts that allow any small alignment issues be corrected without damaging the scope tube,and they also will never leave ring marks on the scope.
