While Czechoslovakia was a part of the eastern bloc, it did a pretty thorough job of developing its own weapons rather than use standard Russian designs. For example, the vz52 pistol, vz52, 52/57, and 58 rifles, the uk59 light machine gun, and more. Well, their military sniper rifle was closer to Russian origin, but still not the same.

The vz.54 sniper was made from 1954 until 1957, and served for many years, until replaced by the Dragunov. It was at heart a Mosin-Nagant rifle, but outfitted with a semi-pistol-grip stock, distinctive Czech scope mount, and a few other features. It was chambered for the standard 7.62x54R cartridge, and was capable of excellent accuracy.
