I was figuring this was some type of AK sold in this configuration, based on the sights, muzzle break, and barrel cover. Not too sure it is a put together, but I may be customized. This movie was rather low budget though, so I don't know if they'd bother building a gun used by this guy and some other henchmen in some shots.
Also, it has a hooded front sight so is it possibly a Norinco of some sort?
