It seems like a good price for most any decent working rifle nowadays. I saw a couple of "Parade" '03 Springfields a while back, no firing pins, and they were over $700. I have a Russian SKS(1951) with CCCP and "arrow in star" markings, but I've had it so long I don't recall what I even paid for it. Maybe $200?
Here is the rifle:
