so how exactly does it work? what will it fire and do they make mags for 410 45ACP or?

Don't know about the 45acp/410. They are also selling the multiple projectiles for you to load into 5.56 cases. The key I see here is "Designed to Shoot" multiple or single projectiles. Since it has rifling it isn't a shotgun. Since it can shoot multiple projectiles it isn't a rifle.

Franklin Armory® Issues Statement on ATF Action Regarding Antithesis™ Firearms

Minden, Nev. – September 19, 2025 – Franklin Armory®, one of America’s leading manufacturers of innovative firearms and accessories, issued the following statement today regarding Franklin Armory’s Antithesis™ line of short-barreled firearms:

Last night, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) requested that we voluntarily bring back all 5.56 caliber Antithesis firearms in advance of the agency issuing a new classification. We were surprised by this in light of the U.S. District Court’s ruling in FRAC v. Bondi.

Out of an abundance of caution and for the well-being of consumers, dealers, and distributors, we are voluntarily requesting all of our customers to return their 5.56 caliber Antithesis firearms for a full refund.

We encourage customers who have taken possession of an Antithesis firearm to contact Franklin Armory Customer service for an RMA (Return Merchandise Authorization) and shipping label. This return does not affect Reformation, the .410/45LC Antithesis, or any other firearm made by Franklin Armory.  

As Facilitators of Freedom, we are actively raising our concerns with various entities within Congress and the Trump Administration. We are also hopeful that continued negotiations with ATF can arrive at a solution that avoids litigation if at all possible.

Be assured, this will not be the final chapter on Antithesis.
