Skorpion vz. 61 E
Ceska Zbrojovka Uhersky Brod (CZUB) · Submachine Gun · In Production · 2009
Also known as: Sa vz. 61, Samopal vzor 61, Scorpion
Overview
The Skorpion vz. 61 E is the modern-production version of the Czechoslovak vz. 61 Skorpion, a compact select-fire submachine gun (machine pistol) chambered in .32 ACP (7.65x17mm Browning). Built by Ceska Zbrojovka Uhersky Brod, it retains the original blowback, open-bolt action with an integral rate-reducing mechanism in the grip that tames the otherwise high 850 rpm cyclic rate, along with the signature single-strut folding wire stock and 10- or 20-round curved box magazines. Small enough to be carried in a holster yet capable of automatic fire, it was designed for vehicle crews, special forces, and security personnel.

Notes
The 'E' designation denotes the current-production model reintroduced by CZUB (production resumed 2009) after the original 1961-1979 run. The rate-reducer in the pistol grip delays the bolt to keep the compact weapon controllable in full-auto.
Background
The Skorpion's rate-reducing device is hidden inside the pistol grip: a spring-loaded weight that catches the bolt and briefly delays it on each cycle, cutting the felt cyclic rate so a gun small enough to fire one-handed does not empty its magazine uncontrollably.
