I just bought a Belgian FAL from a dealer on Guns America. It's a Gun South Birmingham, Alabama pre-ban. I'm very concerned as the front sight and barrel are a matte finish dark gray, but the rest of the rifle is the semi-gloss black. I've been told some were imported like this. The serial number on the receiver 2500661 does not match what I see on the underside of the barrel 01875. Before purchasing I asked the dealer if it was all matching and was assured that it was since the same dealer said he ordered it new way back before the ban, and bought it back from the original owner. Is it possible that they were imported from FN with different barrel serial numbers than the rest of the rifle, when all other parts do match? I have only 3 days to return it if not satisfied.
