The optical sight comprises a transparent optical component (5) and a light-emitting unit (3) in the focal point in a concave, parabolic side in the component facing the user of the firearm. The optical component can be turned from its raised operative position by being arranged on a base cylinder (6') in a lens holder (6). The base cylinder has rotary pins (7) eccentrically displaced in relation to the cylinder geometrical axis. A U-shaped spring (8) has its arms in engagement with recesses in the cylinder and with its base part in the sight. |
