the three guns are, from top to bottom:
1. A gun that was once made with a shoulder stock and longer barrels. It is a “Short Barreled Shotgun” that has a $200 transfer tax, and takes most of a year (at the speed of bureaucracy) for the transfer paperwork.
2. A gun that was made from the beginning in the pistol form factor. It is “Any Other Weapon” under the NFA. It has a $5 transfer tax, and takes most of a year (at the speed of bureaucracy) for the transfer paperwork.
3. A gun that has some vestige or simulacrum of rifling in the barrel… this is a pistol under the law, and a Title 1 firearm that does not fall under the NFA at all. It can be sold over counter at any FFL, and the buyer can walk out with it, except in states like California where one of the “sickeners” that politicians and criminals impose on lawful owners is a waiting period.
Len asks if this makes any sense. Of course it doesn’t make any sense, it’s the law.
