yeah. I am curious how they will "notify" owners of bump stocks though. Its not like anyone filled out any paperwork when buying one, at least that I'm aware of.
That's kinda what the publication is intended to do - put people on notice.
They will likely have a voluntary "turn it in now" period of time. They may also buy them back, but that'll get real expensive real quick. Plus, the industry - and owners - will probably file a lawsuit to prevent enforcement. The whole thing will be frozen until that gets resolved.
Which will be "perfect" timing for the next presidential election.
