The problem with gun shows is that you don't have to know anything about guns to get in. This causes numerous uninformed buyers to walk in, allowing SOME money hungry dealers to prey on them. Hence the $5000 preban ARs that were sighted at shows this weekend. Since many people don't know anything about guns except that they want one, they are easily suckered by these dealers. This issue is make worse by the many dealers who don't really know much about guns themselves. Evidently many dealers have become convinced that selling guns makes them the living equivilent of John Wayne, and they have fabricated stories to match this persona. What this leaves us with is an uninformed, price gouging asshole. He thinks that he is Sgt Stryker, Jane's Recognition Guide, and the Blue Book of Gun Values all rolled into one. He sees everyone as a mark, and seeks to publically discredit anyone who may blow his cover.
Enter you, the informed buyer. You know the law to the letter. As a gun lover, you probably also have an interest in military history. You can identify every black rifle on the table, and know the fair market value for them. You are a decent guy, so it bothers you that he would not only try to rip you off, but he wants to rip off those who know nothing about guns. This is because that kind of asshole makes all of us look bad. You know he is lying, and it offends you.
Unfortunatly , like the rest of society there are assholes in the gun business. Since they treat people like shit, there is no way they would ever be able to keep a fixed gun business. So, they take to the road, hauling their overpriced guns and their overinflated egos from town to town, where they think nobody can see what they are. By the time most customers realize that he was a lying price-gouging fuckhead, he is packed up and gone, never to be seen again. While there are certainly some good dealers at gunshows, many are nothing more than gypsies wih FFLs. They ruin it for the rest of us.
