As the title says, I bought dual dovetail Leupold bases and rings for my new rifle. I finger tightened the bases onto the action and turned in the rings. I planned on using a peice of 1" shaft I have to align the rings(by adjusting them until the shaft sits in them both perfectly). I have heard that you should then lapp the rings with some compound. What compound is appropriate? Is lapping the rings overkill? After lapping, what gets put inside the rings to stop rust? Thanks for looking.
