US12578166 - Apparatus and methods for a gunsight and sighting system

An apparatus and methods are provided for a gunsight and sighting system for use on firearms. The gunsight and sighting system comprises a mount portion coupled with a hood portion. A projection window with a collimated image overlay is secured to the mount portion by the hood portion. A front sight dot is forward of the projection window, while two rear sight dots are rearward of the mount portion. The sight dots may be illuminated by any of various desirable colors to enhance visibility in various lighting conditions. Light sensors disposed at the front of the mount portion detect ambient light and/or light in a target area and accordingly adjust the illumination of the sight dots. The light sensors may be disposed in asymmetric locations of the mounting portion to overcome interference due to light arriving at angles other than in front of the gunsight and sighting system.
