If I was king for the day; I would deregulated all suppressors, SBRs, all rim fires, and any semiautomatic firearm design 100 years old (yes, I am well aware if what that includes); and have them no longer classified as a firearm. Let's say you could get a 8" blow back SMG in 22LR... that would be a lot of fun, but we aren't talking about gangs have shootouts with them.... I mean complete deregulated, no background, no issue with felons, just whatever.
Yes, I mean mail order your FUDD 1911 and have it shipped from Amazon. why not; I don't have an issue with belt feed 22lr maxim being mail ordered.
