Back in the 1990's, Springfield Armory Inc (not to be confused with Springfield Armory) produced some M1 Garands,, mostly made up of old parts.
Finding info on these is pretty sketchy,, but some used surplus receivers, and some used some newly cast Springfield Armory Inc receivers.
The date on this barrel would put it around that time, as some were offered in .308 (not marked 7.62 x 51 like the Danish/Beretta).
Could be one of those. I would strip everything down and start cataloging the markings on all the parts. The barrel may have other markings on the other side.
Any marks on the wood?,, looks to be a new one,, perhaps a Boyds.
Anyway, not a Winchester barrel.
So, could be a Springfield Armory repro model, or a maybe a Fulton Armory, or a James Armory or any of the other guys that put together .308 Garands.
$1400 is an ok price for a shooter. Not a collector's piece.
