I have a Springfield M1A Loaded that has a TRW trigger group, oprod & bolt with a stainless barrel that is unfired. I am checking the gas port for marks but do not see any. I was thinking of completing the rifle out with TRW parts but my question is this. Would a USGI wood stock or fiberglass stock be more original to a TRW built rifle? Which one is original from the factory & which one will get a better price for resale? I'm eyeing a sykes made stock, walnut (which by Different's info would be correct) in great shape with nice marks for around $100 or should I find a USGI fiberglass stock? You opinion is need to help my decision.
