Franklin Armory Antithesis?

Wow, this almost seems like an April Fools or Babylon Bee joke, but it's real.
basically, they found the relevant loophole to defeat the NFA....
A short-barrel rifle (which is restricted by the NFA) is shouldered, and designed to shoot a single projectile, and is less than 16" barrel.
The loophole... shot. 45acp/.410, or any caliber in which ratshot exists. If it is designed specifically for BOTH types of projectiles (bullet or shot), it does NOT meet the definition. And apparently this was contested in court, ruled in FA's favor, and the DOJ has signed off in a settlement agreeing to it.
Meaning, it's simply a firearm, with no tax stamp, no restriction other than basic 4473 background check.

I’ve been reading up on this in the past hour or so and I still don’t know what “shot” projectile it shoots.

.410 shotgun shells

I'm confused, wouldn't that just make it a shotgun? Don't they have barrel length regs on those?

It's in 5.56
FA basically made 5.56 size shotgun shells for it. But it can also fire regular 5.56

here's the new "projectile"
https://franklinarmory.com/shop/firearms/antithesis-multiple-projectile-assemblies/
by definition of the Gun Control Act of 1968, a rifle is stated as:
since this new Franklin Armory can fire more than a "single projectile", it is no longer defined as a rifle, thus, can't be defined as a short barreled rifle.
that's the "loophole"
https://franklinarmory.com/shop/firearms/antithesis-multiple-projectile-assemblies/
by definition of the Gun Control Act of 1968, a rifle is stated as:
quote:
(7)The term “rifle” means a weapon designed or redesigned, made or remade, and intended to be fired from the shoulder and designed or redesigned and made or remade to use the energy of an explosive to fire only a single projectile through a rifled bore for each single pull of the trigger.
(8) The term "short-barreled rifle" means a rifle having one or more barrels less than sixteen inches in length and any weapon made from a rifle (whether by alteration, modification, or otherwise) if such weapon, as modified, has an overall length of less than twenty-six inches.

Shotgun regulations are even more restrictive than rifles - 18” minimum and not just “shoulder fired” like rifles, which is why you don’t see shotgun pistols.
The 45/410 “loophole” the OP mentioned is due to the fact that a rifled barrel that is less than 16” on a firearm that is not shoulder fired is considered a “pistol.” That’s why 45/410 Judge pistols and 45/410 Thompson Center Contenders are legal - if they had smooth bores they would be illegal short barrel shotguns

Yep. And if you look at their site, they have the open letter from the DOJ and ATF stating it is not an NFA regulated item.

Current Status of the Antithesis
As a result of the Agreement, the Antithesis is not a rifle, short-barreled rifle, nor is it an NFA
firearm; therefore, (i) no NFA forms are necessary to sell, transfer, transport, deliver, or otherwise
deal in or possess the Antithesis, and (ii) no ATF Form 5320.20, Application to Transport Interstate
or to Temporarily Export Certain National NFA Firearms, is necessary to transport the Antithesis
across state lines because the firearm is not subject to 18 U.S.C. § 922(a)(4) or (b)(4).
Sales and Transfers of the Reformation and Antithesis Firearms
The Reformation and Antithesis are firearms under section 921(a)(3) of the GCA but are not rifles
or shotguns pursuant to the agreement. When transferring these firearms, FFLs should utilize the
“other firearm” box in block 24 on the ATF Form 4473

A shotgun is something that is intended to be shoulder fired.
Which is why the Shockwave is NOT a Short Barrel Shotgun. And I have my ATF letter for mine.
What's relevant with the Shockwave, which might also be the issue with the Antithesis: the Shockwave is legal because it came from the manufacturer that way (Mossberg, or Remington for the TAC 14). The receiver was specifically designated to have a birdseye grip on it, thur rendering it impossible to shoulder. So it never has a buttstock on it.
With ARs, there's sorta that issue in play. If an AR lower is first designated as a rifle, it can never be a pistol, even if you later swap a short barrel upper onto it. You can go back and forth with pistol-first lowers.
Re the Antithesis- everyone's AR would now be a dual-projectile firearm, but was it DESIGNED to be. That's the question.
Edit to ask: why the downvote?
edit #2: Ok yeah, as I remember it can't be smoothbore, either. Has to have rifling, which would be for a slug in 12 or 20 gauge

It’s a normal 5.56 NATO barrel correct?
What would keep any other AR from firing this new ammo from them? So now every AR ever would fall under this ruling?

I have to give Franklin Armory credit here, that's a brilliant approach. I'm not even going to complain about the price they're asking= it's basically a $500 AR, and you would pay $500 for the "get out of jail" letter from the ATF that comes with it.
I'm curious how this will affect the market- I've been building my uppers and lowers from stripped receivers/parts kits. Lots of us do. Hell, it's even cheaper to buy a complete upper/complete lower and put them together, than to buy a complete AR. Tax purposes.
But nothing we build can get that ATF letter, unless we want to push it ourselves in court and win. And while you can say "I got my SBR tax stamp" for the SBRs you may have, those are still restricted in a lot of ways. If your son or wife isn't on a trust with them, they can't take it to the range by themselves.
This, on the other hand, they can.
Devil in the details- I have a Shockwave. That's legal. The receiver was designated by the manufacturer to be "a shockwave", and thus it isn't a shotgun. Physically, it's a 590 receiver, 100%. But I can NOT legally take a 590 receiver, put a birdseye grip and a short barrel, and call that a "shockwave"... because it was already "a shotgun" at some point in the past. No gunsmith, not even at Mossberg, could tell the difference, other than the serial #.
I suspect that's going to be the case with the Antithesis going forward.

Did I miss an animated diagram on this vid?

No the grooves and lands in the barrel are perfectly straight which is one way of how they are getting around the ATF with their design. There is no twist to the "rifling" in the barrel of the Antithesis.

Franklin Armory gets away with this, because they are stating it was designed to shoot multiple types of projectiles (.556, and whatever they're calling the .556 "rat shot").
Anything PRIOR to this gun, the argument will be, was designed to shoot only the one type of projectile, a bullet in x caliber.
Maybe someone can chase the rabbit-hole on 223/556, since they technically different calibers; but they're both bullets.
As to what would keep your AR from firing this rat-shot; nothing really. It should chamber and fire. Might want to research muzzle device, I do notice it isn't a birdcage on their website. You'd want to be sure you aren't impeding the shot.

WRONG.
The Antithesis has 1:7 rifle twist. The loophole there is it's "designed" for both shot and bullet.
The Reformation has the straight grooves. The loophole there is both the lack of rifling or smoothbore (it's neither), AND it's designed to shoot both shot and bullet.

i don't think this is accurate as each listing on Franklin Armory's website specifies either a 1:9 twist or a 1:7 twist for the Antithesis.
The older "Reformation" is the one that had the straight grooves.
the legal loophole is the multiple projectiles and that's it. i'm sure there's some kind of special geometry going on with the chamber dimensions so this new shot shell works. that's the reason they plan to license the (patent?) rights to multiple manufacturers so they can get these out faster to pass the "common use" test. something Rare Breed Triggers could've done, but they chose greed instead.

meaning, you in theory could get an Antithesis™ barrel, bolt if needed, and be good to go... if you want to roll the dice.
If that's the case, I'd be watching for Ballistic Advantage to start listing Antithesis™ barrels, and replace every pistol barrel with them.

So... all of a sudden everything about this got pulled off the internet.
A video discussing that.
I presume it's gone

It's for loading the projectile that they have.
So you don't ruin it you have to chamfer the rim of the cartridge and the bell it like you would with any pistol cartridge. I also bell a .300 bulk when I'm loading it with lead bullets. If you don't it will take shavings off the bullet.
