What I'd REALLY like to see is the repeal of 18 USC 922 (o)....or better yet, Chapter 4 of the GCA.
I’d love to see all that repealed. Considering how few incidents we’ve had with lawfully owned short barreled rifles, short barreled shotguns, AOWs, select fire, silencers/suppressors in the 88 years since the NFA was signed into law, we’re way overdue for the debate on repealing the whole damned thing. As it is, I believe murders committed with long guns are uncommon, pistols taking the lion’s share of firearms related deaths after you factor in other means. As far as usage of unlawful/unregistered short barreled rifles and shotguns, silencers/suppressors, select fire weapons being used in crimes, it’s maybe a blip on the radar.
