I'm judging that because of the old style flash hider that it has the 553 style bolt upgrade. I'm assuming that the bolt is not serial numbered. Or if it is, it doesn't match the rifle.
Does the reciever say CQB, classic green or carbine? I could see a simple barrel swap between a CQB and a carbine to get the flat top, and then a 553 style bolt upgrade ($700 last time a checked) to get the better bolt system.
