Chongqing Changfeng CF-05

Compact Submachine Gun (SMG) / Machine Pistol (MP) [ 1995 ]

The Chang Feng, with its helical over-receiver magazine, has failed to net much market interest.

The "Chang Feng" became a prototype Submachine Gun (SMG) of Chinese origin developed during the 1990s. Compact and relatively lightweight with a very clean outward appearance, the product was developed around the 5.8x21mm DAP 58 Chinese cartridge. It served in prototype for trials for the PLA but failed to impress and never saw adoption. It was later rechambered for 9x19mm DAP-92 (9x19 Parabellum) and marketed to law enforcement.

Internally there was a wrap-around bolt around the barrel assembly and integrated with the blowback system of operation. One of the more peculiar qualities of the gun was its helical polymer magazine, akin to that as seen in the American "Calico" weapon. The magazine was situated over the receiver in the same way. Another notable quality was its threaded muzzle which supported a suppressor for clandestine operations. Open sights were standard though night sights could also be fitted. The use of polymers throughout its construction made for a handy personal weapon.©MilitaryFactory.com
The early version sported a dual-feed option meaning that the helical magazine could be used (over the receiver) as could a pistol magazine inserted into the grip handle. This feature was deleted in the refined, follow-up version for simplicity. Other more modern features introduced after 2010 include a section of Picatinny rail at the receiver rear and improved markings.

The Chang Feng has been spotted in service with Ugandan police units.©MilitaryFactory.com
