The design of the Sa vz. 61 was unique in its time. It uses the following common operational features found on a submachine gun: an unlocked bolt, magazine inserted into the bottom of the receiver (outside of the pistol grip) and a folding stock. These common features are combined with the following characteristics not usually found in submachine guns: extraordinary small size, fires from a closed bolt, and uses a rate reducer to slow full automatic fire.
The Sa vz. 61 offered by CzechPoint is the semi-automatic version of the original military issued firearm – it is as close as one can get to owning the legendary vz. 61 submachine gun. Except for removal of the full-auto parts and rate reducer, and three modified parts with new safety, this firearm is like those used by Military and Paramilitary units in nearly 20 countries around the world.
