The CS/LS5 is a submachine gun developed by the Jianshe Industries (Group) Corporation of Chongqing. The CS/LS5 design is chambered for indigenous armour-piercing 9×19mm DAP-92 ammunition, but can also use the popular 9×19mm Parabellum round used internationally by armed forces and law enforcement for most pistols and sub machine guns, as well as domestically developed less lethal rubber ammunition.
The CS/LS5 has a short-stroke gas piston system which operates in closed bolt. It comes with a 21.6 cm barrel chambered in 9×19mm Parabellum cartridge, with rear and front iron sights, accessory steel Picatinny rail mounts and a folding stock. It features a left-mounted selector switch for fully automatic (law enforcement/military models) and semi-automatic fire, with the charging handle at the upper front left of the weapon. The exterior of CS/LS5 somewhat resembles MP5 and FAMAE SAF, however these three weapons have completely different internal mechanism.[3]
The standard weapon weighs overall 2.7kg (06lb) with loaded magazine. The weapon was an export-orientated project, and was never accepted into Chinese military and police force.
