"The Škorpion vz. 61 is a Czechoslovak 7.65 mm machine pistol by Miroslav Rybář and produced under the official designation Samopal vzor 61 ("submachine gun model 1961") by the Česká zbrojovka arms factory in Uherský Brod from 1961 to 1979."
The Škorpion's design was finalized in 1961 and named "Samopal Vz. 61". It was subsequently adopted by the Czechoslovak Army and security forces and later exported to various countries.
It is well known around the world for its iconic firerate, which fires so fast the gun creates a buzzing sound similiar to a bee. It is designed to be carried like a pistol, holster and all.
It is best to get as many headshots on a zombie with this.
