Easy does it
Proceed to repeatedly move the bar back and forth. As the lapping process continues the rings will need to be tightened to take up the additional clearance. Periodically remove the bar and clean off the lapping compound to inspect the progress. Continue until 90-95 percent of the rings are making contact.
Determine this by estimating the amount of shiny surface inside the rings. Do not remove so much material that the top and bottom halves touch. Once complete, remove any residual compound with an action cleaner. Now the rings are aligned and any inconsistencies have been removed ensuring the maximum holding surface and minimizing any scope damage when the rings are tightened.
A gap should be even on all sides after tightening the rings. The final step starts out with degreasing the screws and the screw holes for the rings. Place some blue thread-locking compound on the screws. Install the scope in the rings as before and obtain the correct eye relief.
Once the proper eye relief has been established, check the scope reticle and ensure that the scope is not canted, make sure it square. Although canting a scope has no effect on accuracy, it does make windage and elevation adjustments more difficult.
Once the scope is in the desired location, tighten the screws in an alternating pattern until they are properly torqued. This ensures that the rings are tightened down evenly and the gaps between the ring halves are even.
Now that you have your scope has been properly installed, it can be bore sighted. The final step is heading to the range and sighting in the firearm. Once all of this is done you can be rest assured that if you miss it’s not the guns fault.
Remember, pass it on or it will surely pass on.
