URZ AP

The URZ AP (Univerzální Ruční Zbraň Automatická Puška) is modular weapon system of Czechoslovak origin.

The “series of weapons” concept was first pioneered by the French with the Berthier machine rifle and the Stoner 63 was developed by Jiri Cermak in the late 1960s, who also designed the SA Vz.

[2] Most unusual for a Warsaw Pact country, the URZ AP was chambered in 7.62×51mm NATO as it was intended for export.

[3] The URZ AP is a 7.62×51mm NATO calibre delayed blowback battle rifle.

To ease extraction, the barrel has a fluted chamber to prevent ruptured cartridges.
