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.
