Well first thing I normally do is clean the base and rings with a solvent and oil slightly. Removing any rust or manufactures oils. I then fasten the base to the receiver being careful that I don’t let anything slip that might scratched the rifle.

Some guys will suggest to torch the screws with a tool and use loctite but I’ve never done this. I usually tighten the screws but will stagger from screw to screw till they are all tighten to my liking. I will add a touch of oil on the threads to try and prevent any rusting. I then mount the bottom rings making sure they are center if the base has windage screws on the back rings.

Place the scope on the rings and carefully placing the top rings in place. I thread the screws in place but using oil as previously mentioned until it’s tight enough to hold the scope but loose enough for adjustment. Shouldering the rifle I place the scope to my desired eye relief making sure I don’t move the scope and start tightening, staggering from screw to screw like tightening lugs on a tire rim. As the scope is being tighten, I verify that it’s still to my desired setting until it’s all done. I also make sure the space between the rings are equal on both sides.

Some guy may suggest to lap the rings but I have never done this either. I do use a gun rest to hold the rifle in place when doing the work. This helps a considerable amount when working on the rifle. As I do this work, I verify that the scope follows the line of the barrel to prevent any wind age issues during sighting in. Hope this helps. I’m sure other members will add to your thread. Good luck...
