> i don't think you can privately transfer ownership of firearms which is why that was an incidental comment, not the main point.    you are retarded. your ar upper is not serialized at all. your glock is numbered on the barrel hood because austria requires all pressure bearing parts to be numbered and that's the only externally visible area. your shotgun is marked on the receiver, same as the ar, because the retarded atf considers that to be the gun.
