An apparatus and method of manufacturing a sighting device mountable to a gun to assist a shooter in aiming at a target. The apparatus comprises an optical element and a light source which provide feedback to the user regarding alignment with a target. The alignment aid optical element is a ring of transparent material with a user-facing, contoured surface with an inner and outer edge. The contoured surface is coated with a reflective material that reflects a narrow band of light wavelengths. The apparatus further comprises a light source coupled to a mount located at a focal point of the lens wherein the emission of light from the light source faces the lens. The wavelengths emitted from the light source correspond to those of the coatings on the lens.
