Trijicon "A.C.O.G" Reflex II Sight

Only one company would be crazy enough to make a red dot from 1996 to 2020, and that company is Trijicon. This is the undisputed king of wacky carry handle optics.

For it's time, this thing was cutting edge — the "reflex" sight provides quick target acquisition, both-eyes-open shooting, with a completely battery-less amber reticle. While the tritium is long worn out with these, the fiber optic still provides plenty of ability to use this sight during the daytime.
