A dot sighting device for large caliber

The present invention relates to a large-diameter dot Cho Jungyeong site, the Cho Jungyeong is detachable from the upper end of the diffuser portion engine. The present invention enables the rapid and accurate aim by minimizing the time difference. In addition, the present invention provides a structure by inserting a shock absorbing member layer inside the reflector in order by shock to prevent the reflecting mirror is broken, taking into account the distance to the kind of the reference object, characteristic and the target, and the target quickly strike exactly and specifically discloses a technique related to a large diameter dot Cho Jungyeong site capable. Dot sites, aiming, shooting, machine gun, the time difference, the spherical, reflective surface, LED, radius of curvature, aspheric surface, the conic coefficient, a reticle, a ballistic curve
