the PK machine gun due to the switch in Soviet tactical doctrine to the general-purpose machine gun concept, rendering the gun effectively obsolete. KGK general purpose machine gun The KGK (Korszerűsített Gorjunov-Kucher) general purpose machine gun was based on the Goryunov machinegun modified by a FEG team headed by József Kucher (partner of Pál Király best known for his Kucher Model K1 SMG) and produced in Hungary during the 1960s and 1970s. The team added a butt-stock, a pistol grip, a conventional trigger and a bipod from the RPD machine gun, moved the charging handle from the bottom to the side, and redesigned the barrel lock mechanism so that the barrel could be quickly change in the field. Otherwise, the machine gun is identical to an SGM, and most parts are interchangeable. It was used by the Hungarian army on a limited scale, including in the KGKT version as the turret machine gun on D-944 PSZH scout car, and was later replaced by a domestically produced copy of the Kalashnikov PKM machine gun.
