ABSTRACT:
An electronic light dot reticle sight (10) for a firearm has a concave surface lens (22) in a tubular lens housing (11) and an external LED (25) connected via a fiber optic (26) to generate a light point image viewable ahead of the concave surface. A tubular circuitry housing (32) joins lens housing (11) at right angles and has a light adjustment knob (58) which turns a printed circuit disk (42) against a contact (54) on an internal shoulder (39) to select a resistor connection (38, 46) to a spring-loaded common battery contact (49). A spring-loaded pin (73), passing through a recoil bar (70) having an arcuate projection (93) that fits within an arcuate recess (94), provides a shock-resistant connection between lens housing (11) and the firearm. Adjustment screws (31, 94) act at one end of bar (70) to set windage and elevation about the pivot.
