I'm interested in a specific target pistol that I found on Gunbrokers, so I sent a message to the store that posted the listing, asking what would happen if, for some reason, my NICS was denied. I received an emailed reply within fifteen minutes. Here is his reply:
This all seems reasonable to me. I would suggest that if you are interested in a specific purchase, send a message to the person (or store) listing the piece you are interested in. That way there won't be any surprises.If for some reason you were denied, then we would refund to you the price of the pistol minus any fee that we have incurred because of the sale. Gunbroker charges us auction listing fee and if we took a credit card, we would charge you the cc fee. Also, you would have to pay for return shipping.
