The Valmet M78 is a Finnish-made light machine gun chambered for the 7.62×39mm M43 cartridge.


The M78, and the rifles on which it is based, the M62 and M76, are updates of the venerable AK-47 design. Starting with a licensed version of the AK-47 receiver, Valmet set about upgrading the design at every point. Tolerances are tighter than the Soviet bloc AKs while still being generous enough to assure reliability in all climates. The gas piston included small "fingers" near the piston to ensure smoother functioning inside the gas tube, which helped to increase the inherent accuracy of the rifle. Another move toward increased accuracy was the upgraded sights.

As well as the standard version chambered for 7.62×39mm M43 ammunition, variants of the M78 have also been produced chambered for 5.56×45mm NATO and 7.62×51mm NATO ammunition.


In Predator, several of the guerrilla rebels in the Republic of Val Verde, including the man shot out of a tree by Blain, are armed with M78/83 machine guns fitted with synthetic thumbhole stocks similar to that which is found on the Dragunov sniper rifle.


  • The M78/83s used by the Val Verde rebels in Predator, along with the shortened M60 machine gun used by Mac, are quite possibly the exact same guns used by Arnold Schwarzenegger in his earlier film Commando, as firearms for both movies were supplied by Stembridge Gun Rentals.
