The invention relates to a ring for sighting telescopes, intended to fix the sighting telescopes on guns, while achieving various inclination degrees, depending on the distance at which the two fastening rings of a set are mounted on the sighting telescope tube and the height difference between them. According to the invention, the ring consists of a fastening ring (R1) mounted on the objective tube of the sighting telescope and a fastening ring (R2) mounted on the ocular tube, each of them provided with two inserts with coaxial surfaces, having an external spherical surface (Ssf) and an internal cylindrical surface (Scil), with the difference between the height (H2) of the ring (R2) and the height (H1) of the ring (R1) of 0.9 mm ± 25% for the inserts that have an internal cylindrical surface with a diameter of 25.4 mm, 26 mm and 30 mm, of 1 mm ± 25% for the inserts that have an internal cylindrical surface with a diameter of 34 mm, 35 mm and 36 mm and of 2 mm ± 25% for the inserts that have an internal cylindrical surface with a diameter of 38 mm, 40 mm and 42 mm, the set of rings providing different inclinations ( α ) between the axis of the sighting telescope and the axis of the gun barrel, depending on the mounting distance (A) between the two rings (R1 and R2) having values ranging from 70 mm to 150 mm, where, for a difference of 0.9 mm or 1 mm or 2 mm between the height (H1) of the ring (R1) and the height (H2) of the ring (R2), the values of the inclinations ( α ) range between 23'...69'. |
