I have a NIB Trijicon Asmson O.E.G. AR04 gunsight for AR15/M16.
"Armson O.E.G. (Occluded Eye Gunsight) This red dot sight is simply the fastest sight available. It allows you to use both eyes to speed your focus onto the target. One eye never leaves the target scene. Binocular aiming means that while your view through one eye remains focused on the target, the other eye sees a red dot as the weapon is aimed. The result is a super-imposed dot on the target. There is never a contrast problem with an Armson because your brain automatically adjusts any contrast. The dot covers 4 inches at 100 yards and is adjustable for windage and elevation. During the day the sight uses ambient light to illuminate the red dot and at night it is illuminated by tritium."
