Installation of accessories on the optical sight
To expand the functionality of firearms, various accessory mounting systems are used, allowing the installation of secondary aiming devices: laser sights, rangefinders, ballistic calculators, bubble levels, flashlights, etc.

"Mounting for the optical sight, as a place for installing additional accessories, provides a number of advantages:"
- rigid fixation point compared to the quadrilateral;
- convenient position of the attached accessory;
- the possibility of mounting an accessory parallel to the axis of the optical sight, even if the mount is tilted.
The main requirements for accessory mounting systems on the optical sight bracket are to ensure reliability and repeatability of installation. That is, the attached accessory must hold well, not shift during operation, and be positioned in the same place upon reinstallation.
The vast majority of mounting systems used for installing various accessories on the optical sight bracket are rail systems (dovetail) that are secured by a threaded connection. The rail system is designed for precise orientation of the attached accessory in space and prevents it from shifting during operation and under the influence of recoil.
Main problems of manufacturing the tongue-and-groove system for fastening accessories:
- very strict technological tolerances for the manufacture of the pin-slot system, which must ensure a tight connection of the fastening elements;
- the anodizing process (formation of an anodized surface layer) complicates the execution of technological tolerances for the fit of the pin-slot system;
- "Dovetail systems, made according to the principle of cones (for example, 10-15°), have a much more complex processing technology or require special tools."
The SMAI DAVIKA accessory mounting system is a triangle-based mounting system that provides repeatable and reliable installation of attached accessories.
SMAI is a peg-and-slot system formed on the basis of triangles and consists of the following elements:
- the part to which the accessory needs to be attached contains a recessed milling in the shape of a triangle - groove;
- The joining part contains a smaller (relative to the recessed milling) protruding triangle - tenon.
Working principle
The positioning of the attached accessory occurs by shifting the protruding triangle inside the recessed milled triangle forward, until the side edges of both triangles are fully pressed together, and at the moment of pressing the side planes, they become parallel, which ensures the maximum contact area.
Features
The features of this system include:
- Reproducible and reliable positioning;
- The return energy is absorbed not by the threaded connection screws, but by the pin-slot system.
In general, SMAI is an advanced accessory mounting system that ensures repeatable installation of accessories and eliminates displacement from recoil effects.
