The K1 is a
compact assault rifle. It was developed in South Korea by Daewoo. The
K1 was adopted in 1981 or 1983. Since then this compact assault
rifle is used by South Korea alongside the larger
full-size assault rifle. The K1 is used by the special forces and
soldiers who do not need a full-size assault rifle. This weapon was
also exported to several other nations.
The K1 is a gas operated,
selective fire weapon. It is chambered for a standard NATO 5.56x45
mm ammunition. Due to its compact dimensions the K1 is often
referred as a submachine gun. However it is in fact an assault
rifle. It is based on the American
Armalite AR-18 assault rifle, that was superior and less
expensive than M16, but was not adopted by the United States. The K1
has a stamped and welded sheet steel construction rather than
machined forging techniques employed in M16. As a result the K1 is
built to looser mechanical tolerances. It also reduced its
production price. The K1 retains a number of
design features, including a generally similar receiver and bolt
group. However this compact assault rifle has a different gas system which
is more reliable. Also Daewoo designers made some other
improvements to this weapon. Overall it proved to be a very
successful combat weapon.
A fire mode
selector is located on the left side of the receiver. It is
conveniently operated by the shooter's thumb. The fire mode selector
has positions for "safe", "semi-auto", "3-round burst", and
"full-auto". There are semi-automatic only versions of this weapon
aimed at civilian customers and law enforcement market.
