The invention relates to a weapon sighting system comprising a glass subsystem arranged on a pair of glasses, and a sighting subsystem arranged on a sighting device. The glass subsystem comprises a sensing module, a voice module, a first power module, a first image module, a first optical module, a first communication module and a first vision module. The sensing module is used for sending invisible light emitted by an emission module of the sighting subsystem. The communication function is achieved through the first communication module. The first vision module processes all information. The sighting subsystem comprises an emission module, a second power module, a second optical module, a second communication module, a second image module, a second vision module, a second sensing module and a control module. The emission module is used for emitting invisible light in a preset emission manner, wherein the invisible light is used for sighting an object. The second optical module is arranged on an optical sighting system arranged on a sighting device eyepiece. The system can overcome the defect that by means of a traditional firearm sighting system, the human eye needs to get close to the weapon sighting device, separation of the human eye and the sighting device in space is achieved, and great popularization value is achieved.
