XS Sights Systems Shotgun sights are a crucial addition to any defensive shotgun. Utilizing a better front sight set up on your defensive shotgun can provide you with a distinct tactical advantage in any lighting condition. The sight will absorb ambient light during the day in order to store up to use at night or when transitioning to low light tactical situation. To ensure visibility in low light when uncharged the optics orange is primarily based on yellow with a hint of red. Moreover the increased surface area of the convex dot increases light absorption, intensifying the charge of the glow properties of the dot.
