Abstract
A passively and naturally illuminated optical reflex sighting system for a firearm in one embodiment includes a housing configured for detachable coupling to the firearm and comprising a plurality of light collection and transmission windows, an optical lens supported by the housing, a fiber optic element, and a light-transmissible cover enclosing the fiber optic element. The cover and fiber optic element are in visual communication with the housing windows which collect and transmit ambient light to the fiber optic element through the cover. The fiber optic element may be disposed inside and protected by the cover which may be clear. In operation, the fiber optic element absorbs ambient light and generates a reticle on the lens for aiming the firearm. A red or other colored dot reticle may be projected on the lens in some embodiments. No onboard artificial light is used to illuminate the fiber optic element.
