The ČZW 556 was a Czech assault rifle designed and manufactured by Czech Weapons s.r.o in prototype form only in 2004.


The developmental history of the ČZW 556 is not well documented, however it is said to be designed for use by the military and other law enforcement agencies.[1] It, like most other ČZW weapons, appears to be a testbed for delayed blowback technology.
