ZK 381: Czech Pre-War Prototype Battle Rifle
This video explores the ZK 381, a rare pre-war Czech prototype battle rifle designed by Josef Koucký. It details the rifle's technical specifications, including its tilting bolt, short-stroke gas piston, use of ZB26 magazines, and chambering in 7.92mm Mauser. The description highlights its testing by the Soviet Union, which requested a 7.62x54R variant, and its lack of adoption by other major European powers. The video thanks the Czech Military History Institute (VHU) for access to the prototype and recommends their museums in Prague.
