An optical sight system of the invention with a wide range of shooting distances comprises a combination of a telescopic optical sight with a reticle type sight. The reticle sight consists of a partially transparent mirror attached to the outer surface of the telescopic sight at the distal end of the telescopic sight. The telescopic sight supports on its outer surface a light source, which emits a light beam onto the aforementioned partially transparent mirror. The mirror reflects a part of the beam incident on its surface toward a full-reflection mirror attached to the outer surface on the proximal end of the telescopic tube. This mirror is interlocked with the second full-reflection mirror so that when the first full-reflection mirror receives the beam reflected from the semitransparent mirror and carrying the image of the reticle, the second full-reflection mirror closes the eyepiece lens assembly of the telescopic sight and at the same time reflects the image of the target and of the reticle imposed thereupon to the viewer's eye. When it is necessary to use the telescopic sight for aiming at a distant target, the first full-reflection mirror is turned away from the path of the aforementioned beam that carried images of the target and of the reticle, whereas the second full-reflection mirror uncovers the eyepiece lens assembly of the telescopic sight.
