Abstract
Various gun sights for firearms and related methods of use are provided. In one embodiment, the sight includes an apparatus adapted to be mounted at a rear end of a firearm and arranged to occlude one eye of a user of the firearm and to generate an illuminated dot that is disposed such that it is generally centered on the longitudinal axis of the barrel of the firearm. The gun sight produces a collimated beam of light that creates an image of an illuminated dot by either a refractive method or a reflective method. In use, a dominant eye of the user is occluded by the sight and the other eye of the user is focused on the target. The user then adjusts the position of the gun relative to the target such that the user perceives the illuminated dot of the sight to be positioned on the target. In one embodiment the sight includes a dry fire detector that generates some output to the user, such as an increase in brightness of the illuminated dot, at the instant the weapon would have fired if a round had been in the chamber.
