The Škorpion vz. 61 is a Czechoslovakian 7.65 mm submachine gun, developed in the 1960s by Miroslav Rybáø (1924-1970) and produced under the official designation Samopal vzor 61 (\"submachine gun model 1961\") by the Èeská Zbrojovka arms factory in Uherský Brod. Although it was developed for use with security forces, the submachine gun was also accepted into service with the Czechoslovak Army, as a personal sidearm for lower-ranking army staff, vehicle drivers, armored vehicle personnel and special forces. Currently the weapon is in use with the armed forces of the Czech Republic, Slovakia, Angola, Croatia, Egypt, Iraq, Libya, Mozambique and Uganda. Production rights to the submachine gun were also acquired by the Yugoslavian Crvena Zastava factory (currently Zastava Arms), which license-built the weapon in the 1980s as the M84. It features a synthetic pistol grip compared to the original version (a civilian, semi-automatic pistol version was also produced, known as the M84A, also available in 9x17mm Short).
