BOTTOM OF MECHANICAL SIGHTING POINT OF SMALL ARMS WITH ALIGNMENT AND FIXING MECHANISM Russian patent published in 2011 - IPC F41G1/16 

FIELD: weapons and ammunition.

SUBSTANCE: bottom of mechanical sighting point includes stop with groove for draw bolt head, hole for sighting point slide, fuse of sighting point and spring-loaded fastener. In addition, there installed is shaped shoe in which there coaxially arranged on side edges are two upper holes for installation of sighting point slide, two central holes for installation of central screw, two lower holes for installation of axis; at that, axes of holes are parallel to each other; circular limb applied to side edge around one central hole, sighting point slide, which is provided with two slots for interaction with levers of carrier consisting of two levers for interaction with slots of sighting point slots, coaxially located holes and hole in one half of carrier and hole with thread in the other half of carrier for interaction with retaining screw, central thread for interaction with central screw, eye lug to provide the carrier movement along the axis, retaining screw providing fixation of central screw, central screw providing the carrier movement in horizontal plane, and the axis interacting with the carrier eye lug and preventing its skewing.

EFFECT: providing alignment of mechanical sight without additional device; ensuring reliable fixation of sighting point position, namely stability of middle hitting point of the arms in horizontal plane at action of considerable external loads on it.
