That may be a good price if the rifling is in good condition and is not counter-bored; possibly a rare manufacturer, etc. Check for US, French or Finnish rifles hiding amongst the run-of -the mill M91/30s.
A word of warning about Classic Firearms: their customer service is the worst I have ever encountered. I paid for a hand-select Yugo M24/47 and (a month later I might add) received a rifle with a bent barrel. I sent it back to them and never got a replacement. After a month of repeated calls, I was able to get my money back, but I had to eat the cost of shipping.
