US 5,471,777 A · Firearm sighting device

Abstract

A firearm sighting device is disclosed that prevents dominant eye crossover and ensures proper shoulder placement of the firearm for increased accuracy. The sighting device includes an elongated housing having an opening at one end, and a light source is disposed in the housing oppositely from the open end. The housing is adapted to be mounted on the barrel of a firearm with the opening directed toward the butt end portion of the firearm and with the light source near the muzzle end. The housing has a diameter and length sufficient to prevent the shooter's non-aiming eye from seeing the light source, so dominant eye crossover is prevented. The diameter of the housing also prevents the shooter's aiming eye from seeing the light source unless the aiming eye is properly aligned with the barrel, so the sighting device ensures that the firearm has been properly shouldered.
