Franklin Armory Produces NFA Exempt Short-Barrel Firearm

[Longshot231]

I'll let the videos explain it.







There isn't much on there website about it. However, they do say the barrel is rifled.

Here's some more articles about the FA Antithesis. Disclaimer, I haven't had the chance to read through everything yet but will later tonight.

Franklin Armory Declares Independence from the NFA with Antithesis

Franklin Armory announced today the launch of Antithesis, a new class of rifled, short-barrel firearm completely unregulated by the National Firearms Act (NFA).

Trump’s ATF Reclassifies Franklin Armory Reformation and Antithesis

A win for Franklin Armory, the move is another effort by the Trump administration to weaken federal gun laws.

The FA Reformation is old news but I will post these videos anyway. However, IMHO, it's worthless without rifling. Disclaimer, I stopped watching the video when it started keyholing.

Straight rifling?

Straight rifling?

I don't know for the Antithesis but the reformation has straight lands and grooves, AKA straight rifling. However, unless there is a twist to the lands and grooves, then it really isn't rifling.

PS: I went back and read the articles. The .223 caliber Antithesis is designed to fire a special projectile. Actually, it's several nickel plated projectiles.

Here's a picture from one of the articles posted above.

Also from the article:

"How to Use Antithesis Multiple Projectile Assemblies

For optimal performance, Franklin Armory provides specific instructions for the Antithesis Multiple Projectile Assemblies:

Chamfer, Bell, and Lube: Each case mouth must be prepared before inserting the projectile assembly.

Gentle Seating: Carefully seat the projectile assembly into the casing to ensure proper function.

Compatibility Warning: Not suitable for firearms with suppressors or muzzle brakes.

Pro Tip: Always follow the manufacturer’s guidelines to ensure safety and performance. Visit Franklin Armory’s website for detailed specifications and purchasing options."

So with all that said, the Antithesis is kind of worthless to me but kudos to FA for sticking it to the NFA and the ATF!

I don't know. I suppose this is a moral victory of sorts, but the solution to the problem isn't much of a usable solution.

I don’t mean to rain on anybody’s parade….BUT

To me this is the type of thing that losers celebrate…..

After having just had the BBC (the butchered Big Beautiful Bill or BBB) shoved up our backside, we are now acting like losers. We need to get a grip on ourselves.

We would not even be having this conversation if the BBB made it through instead of the BBC.

I agree with both of you. However, this does show how absurd the NFA is and how absurd the ATF is for their interpretations.

Rather than criticize FA, they should be commended for doing something.

My curiosity is beginning to warm with respect to the Antithesis in the 45ACP-45LC-410 configuration. It will be nice to see some reviews on that one.

Ok we’re missing the point. This is a regular 5.56 1-7 twist AR 7.5-12” bbl. But because they made special shot shells for it, it’s exempt from nfa without form4 or transfer fees or interstate restrictions. And shipping and transferring now due to court victories

I'm in komifornia pretty sure I'd be going bye bye for possession of a short barrel shotgun.
