DI Optical has over 26 years of commitment to the research and development of sight solutions for small arms and machine guns.

In 1986, DI Optical saw the beginning as a telescope company doing OEM work for number of different companies. In 1990, DI Optical fulfilled a larger goal of manufacturing  optics for rifles and machine guns. DI Optical has now been exporting optics for the last 26 years.

With the innovative technology and trusted relationships, D.I. Optical has supplied quality products to leading distributors in the USA, Europe and Asia.

DI Optical has evolved into a defense company making rifle and machine gun sights. DI has some of the world’s best technology solutions for both the military and civilian markets.   Notably, the dot sight for the machine gun is the one and only machine gun-specific sight solution in the world that has passed the FCT (Foreign Comparative Testing) program of the U.S Department of Defense.

NATO has awarded us with supplier agreements of machine gun sights after battle-testing then on ships and helicopters. DAPA (Defense Acquisition Program Administration) of Korea has also adopted the models as ACTD (Advanced Concept Technology Demonstration) products in 2009.
