The vz. 52 rifle (often incorrectly called the "CZ 52") is a self-loading rifle developed shortly after the Second World War in Czechoslovakia. Its full name is 7.62mm Samonabíjecí puška vzor 52. Vz. 52 is an abbreviation for vzor 52, meaning "model 52". It fires the unique 7.62×45mm vz. 52 cartridge. It is considered both reliable and accurate, although it is longer and heavier than later assault rifles such as the vz. 58. The first 5000 vz. 52 rifles were made by Považská strojárne Považská Bystrica, but due to production difficulties, its manufacture was taken over by Česká zbrojovka Uherský Brod.
