The PM-63 RAK (short for Ręczny Automat Komandosów—"hand-held automatic commando firearm") is a Polish 9mm 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 also known as the Pm wz. 63.

The weapon proved to be a good PDW for vehicle and tank crews. The PM-63 was exported to a number of Arab and Asian nations, where it was encountered in small numbers during the Vietnam War. Approximately 77,000 were produced from 1967 to 1977.



In 1971 Poland decided to make an export version of their wz. 63, the PM-70. It was identically and functionally the same, but chambered in the world famous 9x19mm Parabellum cartridge. However, due to import restriction on Eastern Bloc Firearms, the gun received no orders, and only pre-production batches were produced.


In 1973, another variant was produced in the .380 ACP cartridge, the PM-73. A suppressed version was also offered. However, it also fell prey to import restrictions. Only prototypes of this weapon were made.

Type 82Edit

During the Sino-Vietnamese war in 1979, a small number of PM-63's were captured from the Vietnamese. In 1982, China started selling their own locally produced version of the gun, the Type 82. The guns were exported to other Asian nations.
