probably a VEPR or SAIGA, he'd be half right since they are manufactured in Russia and imported as sporting rifles and most of the time converted to highcap with muzzle device, etc but not a Russian military issue real past AK-47 or present AKM-47 per se, just a derivative
we could tell you for sure if you see who was the importer/manufacturer and/or what the model number/serial number on the receiver, along with if it is a stamped or milled receiver
also, it depends on what your personal interpretation of what a russian AK-47 is, my opinion is different from the next guy and so on....
My opinion if it is a SAIGA or VEPR then is a "Russian AKM-47....ish rifle", others may not agree, other will say it's 100% a Russian AKM-47 because it has a majority of the design features and manufactured in Russia, there are so many variants per country manufactured for civilian and military use nothing really fits "what is this country's AK-47?"
