The Franklin Armory BFSIII AR-Elite Binary Trigger (brand part no. 00-50631-BLK) is a binary firing system trigger built for the AR-platform, part of Franklin Armory’s third-generation Binary Firing System lineup. Unlike a standard semi-auto trigger, a binary trigger fires one round when the trigger is pulled and a second round when it’s released, doubling the practical rate of fire without any modification to the rifle’s semi-auto action. Franklin Armory rates the BFSIII AR-Elite for use across multiple calibers and AR-platform configurations, making it a drop-in option for shooters who want a distinctly different shooting experience at the range.
