I absolutely support any measure like this, and gun control in general, but I think the gun control discussion might obscure (here, anyway, wouldn't claim to know about in the US which you'd know much better than I) the huge question of: why do so many people want to kill, and take steps to kill, large numbers of other people.The horse has bolted unfortunately, BIden is introducing some sensible gun laws that are supported by the majority. Trump made it easier to get bump stocks and AR15s etc. BIden is trying to close that loophole
