ABSTRACT:
In an aiming device for sport rifles a sighting ring is concentrically supported within a tubular housing. The sighting ring consists of a hollow cylinder composed of lamellas supported at one end and having ramp-like portions at their other ends with inwardly bent fingers defining the sighting ring opening. Annular transparent discs surround the hollow cylinder, one supporting the hollow cylinder at its one end and the other being axially movable and capable of compressing the lamellas to reduce, when moved over the ramp-like portions, the size of the opening and also the outer diameter of the sighting ring. The transparent discs consist of hub sleeves and outer sleeves interconnected by radial spring-steel strips oriented in viewing direction to provide only little obstruction.
