OPTIC SIGHT Russian patent published in 2015 - IPC G02B23/12 F41G1/38 

FIELD: weapons and ammunition.

SUBSTANCE: variable-magnification optic sight is designed for firing of small arms. The sight comprises a lens, an eyepiece, a tube mounted in the housing, which comprises the turning system and the system of magnification change in the moving frame, a mesh, a mechanism of magnification change, alignment mechanisms, a tube is kinematically linked with the alignment mechanisms and has a longitudinal groove. The end of the tube from the side of the lens is made spherical and is connected to the housing, between the tube and the lens a sleeve is mounted, mated with the inner spherical surface of the tube. In front of the lens a threaded ring is mounted, on the other end of the tube the second threaded ring is mounted, which supports the work ends of the alignment mechanisms, and the mechanism of magnification change is made of a pusher, a lever and a handle kinematically connected, and the pusher is connected to the frame of the system of magnification change.

EFFECT: reduction of dimensions and simplification of the structure of the device by simplifying the structures and alignment of the mechanisms of change in the lens equivalent focal length and magnification change, and the sight adjustment.
