sorry, but this gun is illegal no matter what RAA says. a 3rd hole is a machine gun in the eyes of BATF. just went thru all this crap last year with the romanian PSL. some came into the US with the 3rd hole welded up and even though the PSL had NEVER been set up as a FA ,the BATF caught it and impounded the shipment. all the guns already shipped got notified to return them before BATF knocked on your door. you can check all this out on Gunboards ,AR-15,AK-files etc. your gun slipped thru the cracks, you do what you want !
Edit: also look on saiga forum under "other weapons-rifles "
