   The K7 is a South Korean silenced submachine gun. It was designed by Daewoo was intended for special operations forces. Development began in 1998 and was completed in 2000. This weapon The main goal was to develop a less expensive alternative to the German Heckler & Koch MP5SD silenced submachine gun, which was used at the time by the South Korean special forces. The K7 was adopted by South Korean military in 2001. This weapon is also proposed for export customers. It has been exported to Bangladesh, Indonesia, and possibly some other countries.

   In terms of layout, dimensions and function it resembles the Heckler & Koch MP5SD silenced submachine gun. However the K7 is in fact based on the Daewoo K1 or K1A compact assault rifle, but is chambered for 9x19 mm ammunition. Also the original gas system of the K1 has been deleted. Instead the K7 utilizes a simple blowback system.

   The K7 comes with integral non-detachable silencer. The barrel has a number of ports, that divert escaping gasses into the suppressor. As a result the bullet has lower velocity and leaves the muzzle at subsonic velocity. The bullet does not generate sonic shock wave. The K7 submachine gun does not require special subsonic ammunition and uses standard 9x19 mm ammunition, which is widely available. The silencer significantly distorts the sound of gunshots so that it is difficult to pintpoint the location of the shooter.

   A fire mode selector has 4 positions for "safe", "semi-auto", "3-round burst" and "full-auto". A cocking handle is located on the right side of the receiver.

   This silenced submachine gun is fed from 30-round capacity magazines. Though it retains the large magazine well of the K1 compact assault rifle. The K7 is compatible with 30-round magazines of the Uzi and 32-round magazines of Beretta PM12 submachine guns.

   This weapon has a retractable buttstock. There was also a version with an M4-style telescopic buttstock of the new Daewoo K2C carbine.

   The K7 comes with simple iron sights, that consist of front post and rear diopter. The rear sight post is adjustable. A decipherable clamp with Picatinny-type scope rail is proposed as an option. It is used as an adaptor in order to mount red dot, optical or night sights. The K7 has a claimed effective range of 135 m. Actual effective range could be up to around 75 meters.
