If you decide to use one of the US auction sites to bid and buy guns you need to be extra careful. I had two problems with GB. Both times the GB site was a total waste of time in all efforts to either get my money refunded or stop the seller from ripping off other buyers. They neither enforce or even tried to get the seller to follow their "clearly written terms". End result was a loss of money for me and total resolve to never give GB another dime of my money. A few bad sellers can ruin a auction site and when the site fails to police their sellers the buyers are just going to get screwed in the end.
