First, welcome to the boards. Second, it looks like a refurbished Russian that Bubba got his hands on. The trigger housing looks to be from an early Tula given the flat bottom side in front of the guard. If you remove the scope mount to get to the receiver cover, if it is OEM, it should give you some more info as to whether it is a Tula or Izhevsk and the year. Can't tell on the gas block, is it 45 degree angle or curved?
