Its a 1980's production Springfield Armory (Geneseo IL) They made a run of standard and NM guns about 1983Someone's already bid more for a commercially-made "M1 Garand" than it would cost to get the real USGI article from the CMP. That rifle was not "refurbishing" at the factory
Those rifles are one of the reasons I'll never buy another Springfield Armory Geneseo IL made gun.
