CF-05

The CS/LS6, formerly CS/LS06 or CF-05, also known as the Changfeng submachine gun (Chinese: 长风冲锋枪/長風衝鋒槍; pinyin: Cháng Fēng chōng fēng qiāng), is a submachine gun developed by Chongqing ChangFeng Co. Ltd in the early 1990s in response to China's demand for a new submachine gun design.
It was developed by the same team who designed the QSZ-92 pistol, which is now the primary pistol used by PLA and PAP. Originally designed for 5.8×21mm cartridge, after being rejected by the PLA it was offered for export chambered in 9×19mm Parabellum.
