FB PM-63

The PM-63 RAK (short for Ręczny Automat Komandosów — "commandos' hand-held automatic"; the abbreviation itself means crayfish in Polish) is a Polish 9×18mm submachine gun, designed by Piotr Wilniewczyc in cooperation with Tadeusz Bednarski, Grzegorz Czubak and Marian Wakalski. The RAK combines the characteristics of a self-loading pistol and a fully automatic submachine gun. It is in effect an early personal defense weapon.

Development of the RAK dates back to the late 1950s when the concept was first proposed at the Warsaw University of Technology in response to a requirement for a light hand-held defensive weapon for rear-echelon soldiers such as gun crews and vehicle drivers. After the death of the chief designer Piotr Wilniewczyc in 1960, the submachine gun’s development was eventually resumed and completed by the state-operated Lucznik Arms Factory in the city of Radom, where it was produced until 1977. After close examination, the PM-63 was accepted into service with the People's Army of Poland and police in 1965 as the 9 mm pistolet maszynowy wz. 1963 ("9 mm submachine gun model 1963"). Small numbers of the weapon were exported to several Arab countries, Vietnam and the former East Germany. A slightly modified, unlicensed version of the PM-63 was produced by the People’s Republic of China as the Type 82, who sold the weapon to politically allied nations in Asia.
