What is a technical term for the alignment between two scope rings during installation?

The technical term for the alignment between two scope rings during installation is known as alignment lapping. This process involves a method of ensuring that the rings are perfectly aligned with each other to provide a stable and accurate mounting platform for the scope. Proper alignment is crucial because misaligned rings can lead to issues such as scope distortion, inaccurate shot placement, and increased wear on the scope.

Lapping generally involves using a cylindrical tool with a specific type of grinding compound that helps to ensure that both rings are level and parallel to each other. This enhances not only the mechanical stability of the scope but also contributes to better optical performance. Properly lapped rings reduce stress on the scope’s tube and help maintain the accuracy of the rifle.

In contrast, barrel threading refers to the process of cutting threads into a rifle barrel to allow for the attachment of components like suppressors. Ring leveling can also refer to adjusting the scope's angle to ensure it is level for proper operation but does not specifically address the alignment of the rings themselves. Bore sighting involves aligning the rifle’s bore with the scope to ensure that the point of aim is where the rifle is shooting, rather than focusing on the physical relationship between scope rings.
