The Finnish Valmet M78 light machine gun has the standard clubfoot RPK-style buttstock and either a wooden or black synthetic forearm, and sometimes is used to stand in for the RPK in some films. It has been chambered in 5.56x45mm (.223 Remington), 7.62x39mm, and 7.62x51mm (.308 Winchester).
In the early 1980s, Valmet released a sniper rifle version of the M78 with a SVD-styled black synthetic thumbhole stock and black synthetic forearm, called the M78/83 or the M78/83S.
