Agency for Defense Development
Daewoo Precision Industries K2 assault rifle is the standard service rifle of the Republic of Korea Armed Forces. It was developed by the South Korean Agency for Defense Development and manufactured by S&amp;T Motiv (formerly Daewoo Precision Industries) and Dasan Machineries (since 2016). Shoulder-fired and gas-operated, the K2 is capable of firing both 5.56×45mm NATO and .223 Remington ammunition; however, using .223 Remington is only recommended for practicing for short distance. The K2 supplanted the M16A1 assault rifle for the Republic of Korea Armed Forces since its adoption in 1985.
