A good friend has a new, in-the-box CheyTac M200 Intervention in 408CheyTac in Kryptek Camouflage with optics and single mag. He's a non-shooter (don't ask) and would like to sell it but neither he nor myself has any experience in selling/buying firearms online, especially something like this. It arrives at his local FFL gun store today, they have offered to sell it on consignment but a fee wasn't discussed. I figure the more exposure it has to buyers the more he could get for it. Is there a site he could post the rifle on that does eBay style auctions? Suggestions?
