Running a straight bar back and forwards through the two mounted rings at once with a bit of lapping compound.
It’s basically takes off any excess metal and ensures the rings are lined up precisely so when torquing up your scope everything is straight and there’s no undue stress placed on the scope.
Opti lock rings do not need to be lapped as they have a plastic inner that provides a little give and accounts for any misalignment.
Any decent shop where you purchase your scope or rifle from will be able to mount and lap your rings for you.
