The Daewoo K7 was announced in 2003 as a 9 mm silenced submachine gun (with permanent suppressor) for use with the South-Korean special forces. It is based on the K1A infantry rifle, from which the receiver and telescopic buttstock was copied. It was first displayed in the United Arab Emirates in the IDEX (International Defense EXhibition and Conference) 2003 convention.

Design

As the K7 uses a subsonic 9 mm cartridge, there is little need for the weapon to use the Kalashnikov-derived gas operated system of the K1A. Instead, the K7 has a pure blow back system. A 30-round vertical box magazine is used and it can use 30-round magazines taken from IMI Uzis or 32-round magazine from Beretta Model 12s. As the original K1A magazine well was retained, there are internal accommodations for the smaller 9 mm magazine. There are 3 firing modes, single shot, a 3-round burst and fully automatic. However, using fully automatic fire will quickly damage the baffles in the suppressor. As a result of the light bolt, a cyclic rate of fire of 1150 rounds per minute is achieved. The iron sights of the K1A were adapted for use with the low velocity and restricted range of the gun.

uppressor

The suppressor reduces the gas pressure, and the already low velocity of the subsonic cartridge reduces the firing signature significantly. Also, the suppressor distorts the sound so that it is barely recognisable as a gunshot. But just as important, the suppressor contains the entire muzzle flash so that the firer's position is hard to detect, even at night. The noise caused by a K7 is 120 decibels.

Users

Currently, the Daewoo K7 is used by special forces from Republic of Korea Armed Forces and Indonesia's Armed Forces.
