classify any pistol that shoots a rifle cartridge will be classified as a short barreled rifle.
So, any handgun that can fire the
.22 Long RIFLE cartridge is then subject to this?
I'm not aware of a legal definition of what constitutes a handgun or rifle cartridge under the law. And with what little I know of the NFA it's largely a division between .50 and up vs anything smaller.
The laws are written with barrel length and overall length of the weapon defining where it falls - not the cartridge.
A pistol can shoot anything, the Remington XP100 has been around since 1963 and there is no general concern it can shoot .30-06 armor piercing which is legally sold.
Ruger made a revolver than takes .30 Carbine. And you can get AP ammo in that, too. Heizer offers a pocket pistol in 5.56 and is tooling up for one in 7.62xs39.
To define a Short Barreled Rifle under the current law, it would mean changing the definition of what constitutes "rifle" barrel length to mean ANY barrel, and that a rifle would be ANY firearm without a stock.
The ATF is the chief guardian and administrator of what constitutes a rifle or pistol under the law, to change the definitions would mean gutting the NFA completely to accomplish banning a 5.56 AR pistol. Which is why they don't even try.
What the outgoing director did say is that Congress needs to outlaw all 5.56 ammo as cop killer bullets - which would not stand in a court of law simply because the ballistic application is one of the less powerful rounds on the market. Someone IS introducing that bill, where it will likely be considered side by side with a bill requiring the exact opposite, to keep 5.56 from ever being considered for a ban again.
Taking the OP's notion at face value, what I'm reading is a doom and gloom attitude that the political process is broken, when in fact the entire point is that it's WORKING, and the Administration was stymied once again in it's attempt to ban something even if incrementally.
The director is quitting because his legacy is one failure after another, he's thrown the ball to Congress so the Administration can blame THEM for failing to "protect" us, and he's getting out while he can - to the NFL where they can employ him to keep from being investigated, according to some.
Oh Woe is THEM, it's just another day in the trenches for supporting the 2A. If not this, then the next item on the list that the ruling elite fear the people would use against them.
Gun control is about disarming US to prevent being taken out of power when they go too far. A simple examination of world history proves that.
Real patriots are building their own AR pistols in 5.56 just to keep them scared. Anyone who sees the AR pistol as a scary thing needs to understand their attitude is the same as a NY representative trying to outlaw machetes - it's a class warfare action tinged with racism.
