No way its one of those. Look at the size of round that comes out when its cleared. Dosent look like a pistol round. To me it looks like an FNAR. FNAR is .308 and has a bull barrel and could be confused as shotgun diameter. At first when they described it I thought it might be a saiga which is a shotgun on an AK platform but I dont see the gas return on top of the rifle. An FNAR gas return is inside the foregrip.
