Does anyone know anything about subject rifle in caliber 308 Win? I may have a chance to purchase one at a very low price. Gun Traders Guide sez it was a gas operated semiauto and was produced from 1967 to 1973. Barrel lengths 22' or 19" in carbine model. Anyone have any experience with this rifle (or carbine model)? My only experience with an auto 308 was with an M14.
