Dong In Optical released the Dot Sight model DCL120, which can be used with a .50 millimeter caliber heavy machine gun. Company officials say the DCL120 adds precision to a soldier's aim while firing a heavy machine gun to counter threats from armored vehicles and military aircraft.

Company officials say the DCL120, expected to be showcased at the 2008 Association of the U.S. Army Annual Meeting and Exposition held in October, comes with a wide lens that allows for a machine-gun operator to keep both eyes open when firing.

"DCL120 has proved its superb reliability and proved various applications that can be used," Jung In, Dong In Optical chief executive officer, said in a statement.

"With Model DCL120, armed forces can now shorten the trainings, improve the operators' shooting ability significantly, as well as saving the costs for ammunition."
