FIELD: sighting devices for twin-barreled hunting guns. SUBSTANCE: the sight ring is fastened on the stud end screwed in instead of the fastening screw of the gun bolt lever and fixed at the necessary height by a lock- nut, replacing the head of the removed screw; a fore sight for quick aiming is screwed in instead of the gun standard fore sight, it fixes the fore sight position in the horizontal plane for accurate aiming (whose upper part overhands the fore sight for quick aiming) and the installed (if desired) deflection scale. The sight provides for fine fire adjustment for different charges and shots, preserving the adjustment results after removal and reinstallation on the gun; the sight can be easily and quickly removed and installed on the gun, it is convenient for quick fire and fire in the conditions of limited visibility, simple in design, inexpensive, suitable for guns both with horizontal and vertically twinned barrels. EFFECT: simplified design, reduced cost of the sight constantly ready to fire both bullets and case-shots, can be installed and removed with the use of the simplest appliances (screw-driver or knife). |
