I need some atf experts.
Shouldn't adding a rifled barrel to a shotgun make it illegal? Really, all shotguns should be illegal. The logic:
Large caliber weapons are any firearm with a projectile greater than .50 caliber, and are subject to NFA. But the clause specifically excludes shotguns for sporting purposes. A shotgun is defined as a smooth bore firearm designed to propel shot. So, if I add a rifled barrel to a shotgun, shouldn't it no longer be considered a shotgun? And if its no longer a shotgun, shouldn't it no longer be subject to the shotgun exemption in the large caliber weapons category?
Take it a step further. Since the barrel is not the actual firearm, any shotgun designed for home defense is not designed for sporting. Thus any shotty that isn't wood or camo shouldn't be eligible for the exemption.
One more leap down the rabbit hole: since the large caliber weapons clause covers weapons "readily converted to" propel a projectile larger than .50 caliber, then any shotgun with an interchangeable barrel should be illegal, because it can be converted to an illegal weapon by swapping to a rifled barrel.
Perhaps the reason is because they just haven't had the idea to ban it yet. But it goes to show just how crappy the NFA is, and how it allows an agency with no oversight to ban practically anything they want at the stroke of a pen.
