Rick how can you tell the stock is off of a later 03A3? And from what everyone has commented on so far it's looking like this is a arsenal rebuild am I correct in saying this?
Two ways to tell:
1) The stock has bolts, rather than pins. Early Remington M1903A3s had stocks with pins.
2) The RA and FJA: These weren't added until about mid-1943.
I would agree the rifle was overhauled at some point.
