ABSTRACT:
Sight for shotguns with a forwardly widening conic frustum fixed to a mounting on the gun and having in its forward portion a ring extending inwardly from the frustum wall to define with its interior surface a sighting cone coaxial to the conic frustum. The ring emits red or orange light for example towards the shooter's eye, which contrasts with the background to the target. In a daylight version the translucent ring material is treated with a fluorescent agent and/or pigment, and in a night version light diodes are arranged in the ring.
