So, I understand that an SBR is basically a rifle with a barrel length of 16", and overall length of less than (idk some number). However, I see a lot of rifle-caliber guns (AR's, CZ Scorpion clones, lever actions, etc) labeled, marketed, and regulated as "pistols". Hell, some of them even have stocks on them. My question is, how do manufacturers and owners get away with not registering these as NFA firearms and not paying tax on them? It seems to me like these "pistols" walk and quack like a duck (er, rifle). They're rifle calibers, have stocks ("intended to be fired from the shoulder"), have barrels of around 10" or so, and yet are legally bought and sold as "pistols". What gives? Also, as a part 2 to my question, what the hell makes an sbr/sbs so "dangerous" that it needs additional regulation? Of course, I'd like "their" reasoning, not necessarily your personal opinion. I just feel like it's ridiculous that an essentially less-lethal weapon than its full sized counterparts is considered more dangerous.
