This is a test fire video of the Škorpion vz. 61 pistol lower receiver developed by brute. The receiver was designed using a demilled receiver.
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 uses the 7.65×17mm Browning SR (.32 ACP) pistol cartridge, which was the standard service cartridge of the Czechoslovak security forces. It uses two types of double-column curved box magazines: a short 10-round magazine (loaded weight—0.15 kg) or a 20-round capacity magazine (loaded weight—0.25 kg). The bolt remains locked open after the last cartridge from the magazine has been fired and can be snapped back forward by pulling the cocking handle knob slightly to the rear.
