<p>A gunsight comprises a unitary frame (2) for securing to a gun. The frame (2) has a ring (20) with a lens (22) at its front end. A light source (36) is secured to the frame rear end to project a light spot onto the lens (22). The lens (22) and the light source (36) may be independently adjustable in the vertical and horizontal planes, respectively. Alternatively, where the light source (36) is fixed, the lens (22) may be adjusted in the vertical and horizontal planes. The light source (36) and the lens (22) are positioned relative to each other and to the gun barrel axis such that the light spot projected onto the lens (22) is reflected to a shooter's eye who then lines up the light spot onto a target to take aim.</p> |
