This would be kickass. But it would never happen..
Also did you not hear about how private gun buyers invaded the Seattle gun buyback?

"Meanwhile, a number of private buyers set up a makeshift gun show-style event and offered cold hard cash for guns and even lured customers with donuts.
“I pay cash, I don’t give Amazon gift cards,” one dealer told a gun seller.
“It’s a historical firearm, I would hate to see it get destroyed. I’ll give you $100 cash for it,” another buyer offered a gun owner.
Many held up signs that let gun owners know they would pay cash for unwanted firearms."
Also a rocket launcher turned up. And the police said that if the gun was registered as stolen they would return it to the rightful owner. HAHAHA SURE.
