I highly doubt it left the factory with all those parts, anything is possible in that serial number range. By that serial number range they had run out of a lot of USGI parts. I have a 102,xxx rifle, loaded model, and the only USGI parts on it are the rear sights and hammer.
It is a 1997-98 serial number range, post-ban, so the FH is defiantly not original. I can't recall the exact time when SAI stopped selling bare receivers but I think they were still selling receivers during that time frame. To me this appears like a build from a parts kit and receiver, although if it has a commercial SA trigger housing then it is possible that it left the factory that way. Best way to tell is call SAI with the serial number and ask how it left the factory. Nothing wrong with a rifle built from a bare receiver and parts, I've got 3 of them that were built from a stripped receiver.
If the barrel is good and not peeling any chrome in the chamber or bore, $1100-1200 would be a decent deal.
