I've bought perhaps 20 guns through Gunbroker, with only two problems; both mistakes by the seller. The first one was a beautiful Charles Daley O/U skeet gun. The gun I received was not quite as pretty as the one I ordered, which I thought might be due to the lighting on the photos, until I saw it had 28" full and modified barrels. They sent me the wrong gun! When I contacted the seller, he profusely apologized, paid for return shipping, shipped the correct gun, and paid for my background check fees on both guns. The second just recently occurred, where a dealer offered a Taurus Judge 3" Magnum used for a decent price. From the pictures it appeared to be almost new, and in the original box. What I received was a used 2.5" Judge, in good condition, but clearly not the one pictured or described in the ad. Thinking that this might be another case of grabbing the wrong gun to ship, I contacted the seller, only to find out they had "confused" the 2.5" for the 3" Judge. They had no used 3" Judges in stock and tried to offer me a "deal" on a new one. To make a long story short, they stood behind their mistake and sold me a brand new 3" Judge with free shipping for what I had paid for the 2.5" used Judge. I did not have to complain to Gunbroker in either instance, as the dealers immediately corrected their mistakes. Would echo what others have said about making sure there are good pictures of any used weapons, and that the dealer will accept returns should the weapon not be satisfactory.
