GRD (A D.I. Optical Company) has over 26 years of commitment to the research and development of sight solutions for small arms and machine guns.
In 1986, we saw our beginning as a telescope company doing OEM work for number of different companies. In 1990, we fulfilled our larger goal of manufacturing optics for rifles and machine guns. We have now been exporting optics for the last 26 years.
With our innovative technology and trusted relationships, D.I. Optical has supplied quality products to leading distributors in the USA, Europe and Asia.
GRD has evolved into a defense company making rifle and machine gun sights. We have some of the world’s best technology solutions for both the military and civilian markets. Notably, our 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.
