The Škorpion vz. 61 is a Czechoslovak 7.65 mm submachine gun developed in 1959 by Miroslav Rybář (1924–1970) and produced under the official designation Samopal vzor 61 ("submachine gun model 1961") by the Česká zbrojovka arms factory in Uherský Brod.
The Škorpion is a select-fire, straight blowback-operated weapon that fires from the closed bolt position. The cartridge used produces a very low recoil impulse and this enables simple unlocked blowback operation to be employed; there is no delay mechanism and the cartridge is supported only by the inertia of the bolt and the strength of the return springs. When fired, gas pressure drives the case back in the chamber against the resistance provided by the weight of the bolt and its two recoil springs. The bolt travels back, extracting the empty case which is then ejected straight upwards through a port in the receiver housing top cover.
In Project Reality, the Vz.61 is both a sidearm and a primary weapon. It is used by the Militia and Insurgents.
- It is the only sidearm in the game to feature a full-auto capability.
- The Škorpion comes with a stock that's permanetly folded and can't be use.
