That atf Arkansas raid is going to bite them in the butt ….. that’s under the microscope now, we will hear more close to November im sure. No one wants a criminal or nutcase to get a firearm, but as was posted above, these types usually don’t go for 22’s shotguns, and black powder guns like you find at a flea market. The way the law is ( unless it changes) in Missouri, a seller is not responsible for a background check. It’s all on the buyer, and you can’t be held accountable for misuse of the gun you sold…. But who knows at the federal level, and anti gun lawyers will come to bleed you dry if a tragedy happens.
