ABSTRACT:
An aiming device for match weapons comprises a body with a backsight installed thereon, the body being fastened to an axle whose ends are installed in the openings of the base with a provision made for rotation and reciprocating movement by means of screws located in the body and used for vertical and horizontal corrections. Installed in the body is a mechanism for retaining the ends of the axle and the butts of the said screws in constant contact with the base.
This mechanism comprises a spring located in the sleeve of the body, and a slope formed on the bottom of the sleeve at the side of the external surface adjacent to an appropriate slope formed in the base.
The said mechanism provides for a constant elimination of all clearances in the movable joints of the aiming device in one direction, thereby providing, in turn, reliability and accuracy of operation of the device in the course of its entire service life.
