These days, any good condition carbine that is fully functional is worth that amount. A small import mark does bring down the value, but not that much any more. Even if the barrel band is a cut off type 3, it won't hurt the value very much as they are easy to replace and the bands are cheap. It probably isn't a prime candidate for restoration, but for that kind of money, you can't go wrong. The stock is an M2 stock. There is a good chance that it is a Springfield stock. Until you take the action out of the stock or at least remove the handguard, you won't be able to see the marking. It would be on the top of the stock on the left side almost up at the nose of the stock. Very often that is the only marking on a Springfield replacement M2 stock.
