Antithesis™ Binary AT-125™

Franklin Armory® Antithesis™ Binary AT-125™

The Franklin Armory Antithesis is a new class of firearm, completely unregulated by the National Firearms Act (NFA).


The patent pending Antithesis is intended to fire both, multiple projectile ammunition and traditional single projectile ammunition through a rifled bore in a shoulder fired firearm with a barrel less than 16 inches long!


Antithesis is classified solely as a “firearm” under the GCA, Antithesis requires no NFA registration, no NFA tax, and is not subject to onerous entanglements, such as interstate transport prohibitions. The innovative Antithesis Short-barreled Franklin (SBF) firearm is simply transferable with a Form 4473.

Buying a complete firearm or lower from Franklin Armory® is easy, safe, and legal. Federal law requires all firearms be shipped to a licensed dealer.

Once you have placed your order, please have your FFL dealer email us a copy of their license, include your name, and the order number you received.

Orders cannot be processed until we receive an FFL for your order, the posted lead time will begin once your dealer's FFL is received.
