S&T Motive (Daewoo) K7 History
South Korea has substantially updated its small arms stockpile by seeking locally designed, developed and produced weapons, thereby reducing foreign reliance on such war materiel. This has resulted in a range of "K"-marked weapons that play a variety of roles on the battlefield, from assault rifles and machine guns to service pistols and submachine guns. In 1981, the K1 submachine gun entered service, and in 2001 a silenced version of the weapon was introduced, manufactured by S&T Dawoo (today S&T Motiv).
Design work was carried out by the Defense Development Agency and lasted from 1998 to 2000.
The K7 differs from the original frame in a departure from the K1's aero direct shock system. Instead, it relies on the tried and true recoil action. It also supports the ubiquitous 9x19mm Parabellum pistol cartridge instead of the .223 Remington, making it more in line with world submachine guns. The total weight is 3.38kg and the total length is 790mm (610mm when the wire is folded). Iron sights are mounted above the receiver as usual.
The pistol grip is angled back for a firm, ergonomic grip. The silencer is located above the muzzle, increasing the length of the gun from the original K1 form. The weapon is fed from a 30-round detachable magazine that feeds into a well in front of the trigger group.
Loads a 9mm magazine into a traditionally loaded .223 Remington magazine.
The rate of fire is 1,100 rounds per minute and the effective range is 150 meters. Operators can use typical firing modes - safe, single, triple burst and fully automatic.
Unlike other "suppressed" weapons that try to be silent but use conventional ammunition and silencers in their design, the K7 relies on subsonic ammunition and silencers in the 9x19mm Parabellum cartridge, making it a true silenced weapon. The silencer is used to reduce the pressure that builds up at the muzzle when the shot is fired, this slight delay, in turn, reduces the noise ("click") produced and limits the audible signal - when you're unsuspecting Useful for destroying Sentinels.
The K7 was commissioned by the Republic of Korea Army Special Forces to replace the in-service Heckler & Kock MP5SD6 series artillery. The service specifically calls for South Korean submachine guns as an economical, homegrown design alternative to German products (which must be imported at cost).
The series has since been adopted by other special forces around the world, including Bangladeshi SWADS and Indonesian KOPASSUS agents.
