pictured below are standard two piece base drift adjustable for windage.
the matching rings mate up with front and rear base respectively so initial mounting of the front ring which typically has the hole goes on at a 90 degree angle to the rifle. the rear ring only one screw is removed the base is twisted into position in a swinging motion.
to get initial line up the front ring and rear ring lower halves are set in place it often takes a wring wrench as pictured
to properly attach the front ring without damaging the ring itself. that wrench runs about 14$. you can do it with a crescent wrench and some padding ut you risk ring damage.
put the rear base on tighten the screw down that you removed to slide the base on clamping it in place. test fit the scope to front and rear bases twist front base WITHOUT the scope and retest fit till it sits without any stress on the scope. often people (gunsmiths) attach both rings to the scope and force fit them together. this can easily damage the scope.
once you have the rings setup level the rifle then level the scope using some cheap hardware levels or the wheeler level-level-level system.
once both are level then torque down the top ring halves using your inch pound torque wrench which any true rifle person should have.
once its all set the scope is then mechanically zeroed (DO NOT BORE SIGHT AND ADJUST WINDAGE WITH THE SCOPE DIAL!!!! thats another spot gunsmiths screw up) windage is adjusted using the rear base screws and ideally shooting till your left/right is spot on using just the base. this is achieved by loosining the screw in the direction you want to move the scope then tighting the other screw and locking everything back down to test fire. repeat until windage is correct. if you do it right you should never have to touch the windage knob on the scope.
once you have it all siighted in the scope can be removed for cleaning as needed and will return to zero by removing ONE windage screw and twisting the scope off. so long as the other screw isnt nudged (good idea to lock tite it in place once windage is set) you wont lose zero.
the benefit of a good inch pound torque wrench is you can change tension on the action screws which can greatly increase or decrease accuracy. improperly tensioned action screws can greatly affect the accuracy of your rifle in a negative way by up to as much as 3 inches of groups size or more. in fact i have a friend that bought a new savage couldnt get it to group better than 6 inches i retorqued his action screws to a nice even 45 inch pounds front back his groups immediately went sub-moa...
personally i would invest in the simple cheap tools to do your own scope and such it will pay off in the shooting portion as there are damn few gunsmiths that are true smiths and you sure want find one in a big box shop.
