S&T Daewoo XK8

S&T Daewoo XK8, also known as DAR-21 (Daewoo Assault Rifle-21st Century), is a 5.56×45mm NATO bullpup assault rifle developed and manufactured by S&T Daewoo intended to replace Daewoo Precision Industries K2 assault rifle for the Republic of Korea Armed Forces. XK8 was the first firearm developed solely by the Korean defense company without the request from the military. However, after the field tests by Republic of Korea Army Special Warfare Command, it was rejected and was not mass-produced. The rifle is now offered for export only.
