SMA, Gunbroker.com is the ebay of guns, a national market. You'd have to go to the site to see how to list it....I think the service is free to list. However, there are other local sites around the country; in Virginia there is Vaguntrader.com, etc. As Steve suggested you could list it here in the for sale section; however, the guns listed on this site tend to be higher end than yours; but no harm in trying - it's free until it sells.
