For me, GunsAmerica is just to clunky and has too many games being played.
I haven't used AuctionArms in some time but ought to give them a try again to see what my response is.
Gunbroker.com is the auction site of choice for me for both buying and selling firearms related items. Yes, much of what is listed is shown at high retail but it's is easy to find what I want at lower prices most of the time. As a seller I appreciate the automatic resisting (up to 50 times) the improved interface and the dynamic bidding. When a bidder bids in the last minute the auction is extended by a minute to cut down on sniping and allow someone else to up their bid. I prefer that as a seller but prefer auctions with a hard closing time when I'm buying.
I don't list with reserve pricing and have no patience with it. I figure you should list an item for the least amount you'll take for it and not be a PITA to folks who have to hunt for your bottom line. I appreciate that both AuctionArms and Gunbroker show on the search page which are reserve auctions which lets me ignore auctions with reserves. List your items for the least you'll take, you won't be disappointed and it may sell for quite a bit more. If you list at a fixed price that's all you are going to get. In my mind the only times to use a fixed price are when I want to sell in a hurry and price it low or when a lot of other folks have the same item as similar prices.
One downside of GB is that many items are priced well over normal retail but I think that is a result of the policy that you only pay for an item when it sells. If they had a way to sort searches by price it would make it easier to screen out the folks who list at retail plus 20%. Optics, in particular seem to be listed at well over the current retail prices.
I get pretty frustrated with auctions that ask you to contact them to see if the item is in stock. I can't think of anything less professional. I don't bother with those sellers either. I also don't like auctions with stock photos and disclaimers that the picture may not match the item and which tell you do check the makers website for details. Would you do business with a store that handed you a picture, told you it might not be of the correct items and expected, had a price tag on it that read that it really wasn't the price etc and still expected you to buy something?
All right, I'll put away the soap box...
