Legality of buying/selling braced firearms

[Spats McGee]

There are probably hundreds of thousands of people who know nothing about the pistol brace rule change. They puchused theirs legal, aren't immersed in gun culture like we are, so they aren't keeping up to date on news regarding firearms. I know several casual gun owners who couldn't even tell me the model and, in some cases, even the manufacturer of the handgun they own when I inquired. They only know the caliber. I expect everyone to know the rule.

I recently had a discussion with a retired federal law enforcement agent who is now working in a county detention facility, and he had zero idea about the rule change, as in "hadn't heard about it at all."
