The RPK (Ruchnoy Pulemyot Kalashnikova, Russian: Ручной пулемёт Калашникова or “Kalashnikov hand-held machine gun”) is a 7.62x39mmlight machine gun of Soviet design, developed by Mikhail Kalashnikov in the late 1950s, parallel with the AKMassault rifle. It was created as part of a program designed to standardize the small arms inventory of the Red Army, where it replaced the 7.62x39mm RPD light machine gun. The RPK continues to be used by the armed forces of countries of the former Soviet Union and certain African and Asian nations. The RPK was also manufactured in Bulgaria, Poland, and Romania.
