The PK is a machine gun of Soviet origin. It was developed in the early 1960s by Mikhail Kalashnikov to replace several types of older machine guns in Soviet service. The name PK stands for “Pulemyot Kalashnikova”, which is Russian for “Kalashnikov machine gun”. Due to its reliability, firepower, and limited weight, it became a very successful design. Over 1 million copies have been produced. Designed by Mikhail Kalashnikov for the Soviet military, the Pulemyot Kalashnikova (PK) was introduced in the early 1960s as a replacement for the SGM and RPD machine guns. The general-purpose 7.62mm Kalashnikov -- PK, PKS (on a tripod), PKB (armored transporters), PKT (tank), PKM (modernized) -- is a powerful automatic weapon intended to defeat enemy personnel and weapons systems. The Soviet Ministry of Defense published this instruction manual for the use and maintenance of the PK in 1987, and this is the first time an English translation has been made available to the general public.
