The invention discloses a sighting telescope with a damping mechanism. The sighting telescope with the damping mechanism comprises an eye lens, an eye lens pipe is connected with the eye lens throughthreads, a lens cone is arranged on the right side of the eye lens pipe, a zoom ring is arranged on the right side of the lens cone, a correction pipe is arranged on the right side of the zoom ring, and the correction pipe is connected with the zoom ring through a connecting ring. An objective lens is arranged on the right side of the correction pipe, the objective lens and the correction pipe areintegrated, an adjusting handle wheel is arranged at the top end of the correction pipe, and the adjusting handle wheel is movably connected with the correction pipe. A side focusing device is arranged on one side of the correction pipe, clamping seats are arranged on two sides of the bottom end of the correction pipe, a spring seat is arranged above the clamping seats, the spring seat is weldedto the clamping seats, springs are arranged in the spring seat, one ends of the springs are welded to the correction pipe, and the other ends of the springs are welded to the spring seat. When the clamping seat is mounted on a gun, the sighting telescope can be effectively fixed, the springs effectively buffer recoil force, and internal parts of the sighting telescope are protected. The sighting telescope with the damping mechanism has the damping effect, and solves the problems in the prior art.
