The M-60 machine gun was a type classified in 1957, by the U.S. Army. It fires the standard NATO 7.62 mm round and is used as a general support crew-served weapon. It has a removable barrel which can be easily changed to prevent overheating. The weapon has an integral, folding bipod and can also be mounted on a folding tripod. That's the real one. Ours won't ever overheat, but the action can be “HOT, HOT, HOT!”. Our weapon has a 12-shot, semi-automatic trigger.
