Made the trade, but mainly because I figure there's a more broad audience with a rifle than the bow. The rifle has a Duracoat finish on it, and I've found out it's a RIA/SA hybrid. Interesting history:
RIA got out of the '03 rifle business in the '20's, but had several thousand (around 50K) receivers left over. They sent the receivers to Springfield Armory, and Springfield finished the rifles out and used them. All of the receivers were nickel steel, so were safe to shoot. Most (as in this case) were already stamped Rock Island Armory and had serial numbers that went up into the low 400,000's. Springfield put their own barrels on these rifles, and they were issued.
Thanks for all your help!
I'm still considering selling it at $400, if anyone is interested.
