If the auction house charges the buyer he will bid less. Ridiculous fees charged to sell is not right. If you have a thousand dollar gun and the buyer offers 800 because of a 20% fee and you pay 25% you get $600. Why not sell it here or another site and discount what you think it is worth and it should sell. You have to ship no matter what anyway. The only real extra work is taking pictures and answering a few questions. No reason you cannot say "as is" also. I am sure many of us have guns we bought years ago and have not shot it since then.
