Historical profile
Development
The RPK (Ruchnoy Pulemyot Kalashnikova) is the squad light machine gun developed in the USSR in the early 1960s as an evolution of the AKM, to replace the RPD in the squad automatic weapon role.
Officially adopted by the Red Army in 1961, it shares about 80% of its parts with the AKM, simplifying logistics and training.
Design
Compared to the AKM it features a longer, heavier barrel (590 mm), a folding bipod under the muzzle, a reinforced receiver and a 'club-foot' shaped wooden stock.
It uses 40-round curved magazines or 75-round drums, and is also compatible with standard AKM/AK-47 magazines.
Operational service
Distributed across the entire Warsaw Pact and produced under license in Romania (PM md. 64), Bulgaria, Yugoslavia (M72) and elsewhere. It was gradually superseded by the 5.45×39 mm RPK-74 from 1974.
It saw service in all major late-20th-century conflicts: Afghanistan, the Gulf Wars, Chechnya, Iraq, Syria and Ukraine.
