Franklin Armory’s BFSIII or Binary Firing System III trigger is an interesting option for those looking for a non-standard fire control group for their AR rifle. It has a 4.5 lbs. trigger pull +/- .5 lbs., and aside from the standard safe and fire modes, it comes with a third ‘binary’ mode, which discharges a round upon pull and release. If the shooter wishes to disengage the second shot upon trigger release, they can simply move the selector to the standard fire position, and the binary mode will deactivate. Also included with the trigger is a heavier buffer spring, which reduces the possibility of hammer follow.
Franklin Armory’s BFSIII is compatible with most AR trigger-compatible weapons, the Franklin Armory F17 series, and .22 LR and 9mm uppers without modification.
