The PM-63 RAK was a compact Polish machine pistol developed in the late 1950s and adopted by Polish military and security organizations during the Cold War. Designed by Piotr Wilniewczyc, the PM-63 emphasized compact dimensions and portability while retaining a distinctive open-bolt operating system. A period parts-kit configuration may be encountered with components such as the barrel, shoulder stock/rig components, and multiple magazines.
