The bolt and carrier design are similar to the AK-47 and other modernized Kalashnikov-pattern weapons, as is the stripping procedure performed to remove those mechanisms from the gun for cleaning. Note the non-fluted barrel and revised flash hider. PKM general-purpose machine gun with modern black polymer furniture and a 100-round ammunition box. The PK uses the 7.62×54mmR Eastern Bloc standard cartridge that produces significantly more bolt thrust when compared to the Eastern Bloc 7.62×39mm and 5.45×39mm intermediate cartridges. The original PK was a development of Kalashnikov's AKM assault rifle and the accompanying RPK light machine gun design that featured stamped receivers. Nikitin's and Sokolov's machine gun design was later used in the 12.7 mm NSV heavy machine gun that was put into production in 1971. The PK/PKS was put into production at the Kovrov Mechanical Plant and used the tripod mount and an ammunition belt boxes originally designed for the Nikitin-Sokolov prototype machine gun. The Kalashnikov design was found to be more reliable and cheaper to manufacture than the design of Grigory Nikitin and Yuri Sokolov. The Main Missiles and Artillery Directorate and the Ministry of the Defence Industry preferred the Kalashnikov design. The Kalashnikov and the Nikitin-Sokolov prototypes underwent service tests in the Central Asian, Odessa, and Baltic Military Districts, as well as at the Vystrel officer training courses in late 1960. Their machine gun prototype was based on the well-proven gas-operated rotary-bolt design of the Kalashnikov-pattern arms. Kryakushin, as well as Startsev, Kamzolov, Koryakovtsev, Yuferev, joined the competition. Kalashnikov, and further consisting of V.V. However, when the Nikitin-Sokolov machine gun was almost completed, a team of Izhevsk Mechanical Plant designers, headed by M.T. Based on the results of the tests it was decided in 1960 to manufacture a batch of Nikitin-Sokolov machine guns for service tests and then put the machine gun into production at the Kovrov Mechanical Plant. Sokolov, successfully passed field tests. In 1958 a machine gun prototype, developed by G.I. The Main Artillery Directorate of the Soviet Union (GRAU) adopted specification requirements for a new 7.62 mm general-purpose company and battalion-level machine gun that was to be chambered for a rifle cartridge in 1955.
