Patent ID: 7797873

Claim:
Sighting system for a fire arm having a barrel, comprising a single indicator light ( 6 ); a sighting device ( 7 ) providing an alignment opening ( 8 ) with a longitudinal reference plane (XoX′) which is parallel or mainly parallel to the axis (Y-Y′) of the barrel ( 4 ), and which is aligned with the indicator light ( 6 ); an inclinometer for obtaining a measured elevation angle (A) of the fire arm ( 1 ); a ballistic calculator ( 9 ) connected to the indicator light ( 6 ) and to the inclinometer, arranged for calculation of a calculated elevation angle of the fire arm ( 1 ) as a function of the distance of the target ( 18 ) and to control the indicator light ( 6 ) so as to signal at what moment the measured elevation angle (A) corresponds to the calculated elevation angle.
