[edit] Classification

The K1 is classified as a submachine gun in Republic of Korea Armed Forces because the K1 was intended to replace M3 Grease Gun. The K1A is the upgraded version of the K1. All K1s in Republic of Korea Armed Forces have been modified to K1A.

[edit] Differences

While the K1 carbine is commonly regarded as a carbine version of Daewoo K2 assault rifle, it is better to consider K1 a separate carbine. Because,

The development of K1 was completed earlier than that of K2.
The K1 uses the direct impingement gas system, while the K2 uses AK-47 style gas piston system.
The K1 has 1-in-12 rifling twist for .223 Remington, while the K2 has 1-in-7.3 rifling twist for 5.56x45mm NATO (FN SS109).
