An out-sized replacement for the M3 Grease gun in South Korean military service, the K1 was classic Daewoo hardware. Larry Vickers shows off one in the above video.
Designed in the late 1970s to produce an indigenously-produced answer to the Korean military’s need for a sub gun, the K1/K1A is a 5.56mm buzzsaw, capable of firing at cyclic rates of up to 900-rounds-per-minute. Compact at just 26-inches with its stock retracted, it isn’t quite an SMG, but it gets the job done.
Daewoo tanked in 2002 but their arms division have been made since then by Busan-based S&T Motiv, which currently supplies the K1’s successor, the imaginatively-designated K2, to the South Korean military.
