A typical sight mounting system consists of two parts, the scope rings and the scope base. The mounting generally positions the telescopic sight axis without cant over the receiver and bore center axis, to make sighting in and the use of ballistic tracking at various ranges for the user as easy as possible.
There are also sights that actively project an illuminated point of aim (a.k.a. "hot spot") onto the target itself so it can be observed by anyone with a direct view, such as laser sights and infrared illuminators on some night vision devices, [citation needed] as well as augmented or even virtual reality-enabled digital cameras ("smart scopes ...
The SIG Sauer 200 STR has an 11 mm dovetail on the receiver for mounting a diopter rear sight or a scope sight, either directly or via a Picatinny rail adapter.. Dovetails come in several different types and sizes depending on manufacturer, but the most common are the 11 mm and 3 ⁄ 8 inch (9.5 mm).
The idea behind these mounts was 'one lens, any mount'. A retailer, for instance, only had to keep one lens model and a few, cheap mounts, rather than many lenses in every different lens mount.

The M39 lens mount is a screw thread mounting system for attaching lenses to 35 mm cameras, primarily rangefinder (RF) Leicas. It is also the most common mount for Photographic enlarger lenses. True Leica Thread-Mount (LTM) is 39 mm in diameter and has a thread of 26 turns-per-inch or threads-per-inch (tpi) (approximately 0.977 mm pitch) of ...
