Every seller has the right to refuse a firearm upon examination in person. I would refuse to be committed to purchase a firearm that I had only seen online pictures of. Too many issues can be hidden, especially ones that are mechanical, or inside of the firearm.
Additionally, folks can easily swap guns before they show up for the deal, or make mods to it, or damage it, etc.
The picture on the site could be a year old and they've fired it a lot in the interim.
It is unreasonable to commit someone to purchase a used item when they will have the opportunity to examine it in person.
Not only that, but the right to allow a buyer to physically examine an item and refuse it is clearly stated in the ODT Rules & Regulations: "Members are allowed to inspect and reject an item or trade at a meet, there is no requirement that they must purchase the item, they are just committed to showing up to the meet."
I know that no one reads them, but the Rules & Guidelines can be read in their entirety right here: https://www.theoutdoorstrader.com/help/rules/
A used gun would be no different from a used car. You agree to a price over the internet on a used car, show up to examine it in person, and find rust and fluid leaks that weren't apparent in the picture. At that point, the buyer has the right to refuse to purchase.
