The Franklin Armory Binary Trigger is a unique trigger system for firearms that operates in a binary fashion. The binary trigger system allows the shooter to fire one round with each pull of the trigger and one round with each release of the trigger, hence the name "binary." This type of trigger system can provide faster and more efficient shooting for the user, but it's important to note that the use of a binary trigger system may be restricted in some jurisdictions, and it is essential to familiarize yourself with the laws and regulations regarding their use before purchasing or installing a binary trigger in your firearm.
