Franklin Armory BFSIII AR-S1 Flat Trigger Binary Trigger System

The Binary Firing System ™ GEN 3 (BFSIII™) is a 3-position trigger. In position 3 it fires one round on pull and one round on release, making it the fastest semi-automatic trigger on the market. This trigger is ideal for both tactical and competition use. The BFSIII™ provides greatly reduced split times between rounds, allowing for tighter groups. Now with a flat trigger!
