Dioptrical sight

FIELD: weapons and ammo.

SUBSTANCE: for the usage in shooting sports, biathlon, and sports and entertainment shooting galleries. The matter of the invention lies in the fact that the dioptrical hole of the sight is performed by crossing of two through orthogonal rectangular holes made in moving plates. The plate with the vertical through hole is performed with the possibility of moving in the horizontal direction. The plate with the horizontal through hole is performed with the possibility in the vertical direction. There are scales with zero points in the middle of the diptrical hole located on both plates along the longest sides of the through holes. The moving of the plates is performed in a particular case by screw mechanisms. The width of the through holes performed in the plates may be adjusted with the help of mechanisms.

EFFECT: possibility of creation of the easy sight providing high shooting accuracy, as well as the possibility of horizon adjustments without moving the sight, for small-caliber and air rifles.

SUBSTANCE: sighting device of small arms comprises a foresight and a backsight. In the backsight's case on the axis there are two spring-loaded sighting planks installed at both sides of the axis in mirror reflection to each other. On a sight pillar that is nearest to a gunner's eye there is a dioptre, and at the farthest - a slot. In longitudinal slots of the backsight's case there is a runner capable of selective interaction with elements at sighting planks that determine their working position. On each sighting plank there might be at least two such elements, which determine position of sighting planks during interaction with the runner, which corresponds to the selected distance of firing. The foresight and backsight may be installed on a Picatinny rail fixed on a receiver.

EFFECT: improved accuracy of sighting.

SUBSTANCE: invention relates to optical instrument making and can used in optical sights of sporting rifles, fowling pieces and combat firearms. The proposed sight incorporates a casing to house the device that displaces laying mark along with the light-diode radiator that shapes the said mark, laying mark brightness control device, power supply, optical collimating assembly, mirror and reflector representing a thin transparent plate. The collimating assembly comprises two optical lenses with their spherical surfaces tightly pressed against each other. The said surface of one of the said lenses features a multi-layer interference coat applied thereon to completely reflect the laying mark light beam from the radiator. The other surface features a semi-transparent multi-layer interference coat that reflects 50% of the laying mark light beam. The mirror and reflector are arranged at 45 to optical axis and horizontal plane located between the radiator and collimating assembly. The device that displaces laying mark consists of two slides. One of the latter accommodates a mirror arranged at 45 to the casing base.

EFFECT: higher accuracy of laying mark adjustment, simpler design.
