Trijicon

Trijicon is an American manufacturing company based in Wixom, Michigan, that designs and distributes optical sighting devices for firearms including pistols, rifles, and shotguns. Trijicon specializes in self-luminous optics and night sights, mainly using the low-energy radioactive isotope tritium, light-gathering fiber optics, and battery-powered LED.

The Company was founded in 1981 by Glyn Bindon as Armson USA, the sole US importer, and distributor of the Armson OEG. The Armson OEG was an occluded-type gunsight that used tritium and fiber optics in its construction and was manufactured in South Africa. In 1985 Bindon reorganized the company as Trijicon and began manufacture of night sights for pistols. Trijicon introduced a tritium-illuminated telescopic sight for the US Military called the TA01 4×32 Advanced Combat Optical Gunsight (ACOG) in 1987.
