Franklin Armory AR-S1 Titanium Gold Nitride Binary Trigger - 5645A-TIN

The Binary Firing System from Franklin Armory is a 3-position flat face trigger featuring user-friendly operating positions to switch from safe, semi-auto, and binary. The BFSIII, operated in position 3 (binary) makes it the fastest semi-automatic trigger on the market firing one round on pull and another on release.  The BFSIII trigger is ideal for any shooter as it is easily installed without a gunsmith and requires no proprietary bolt carrier group. The BFSIII provides incredibly reduced split times between rounds, allowing for tighter groups on target and a higher volume of rounds downrange.
