Like any other online sales sight it is a buyer beware thing. I have used Gun Broker several times because they have a list of the sellers rating and full discloser from the buyers feedback. Be very carful about who you buy from. Like they say, if it's to good to be true it probably is. Also I personally always take the longer payment way and sent a certified bank check to the seller. That way I have his actual address and he doesn't have my CC number. Stick with a seller with lots of sales and great feed back you'll probably be all right.
