The Franklin Armory BFSIII 22-EZ (brand part number 02-50041-BLK) is a drop-in Binary Firing System trigger built for the Ruger 10/22, giving the rifle three selectable modes: Safe, standard Semi-Auto, and Binary. In Binary mode, the trigger fires one round on the pull and a second round on the release of the trigger — two rounds per trigger cycle rather than one, but never more than one round per single function of the trigger, which is why Franklin Armory’s Binary Firing System has been evaluated and confirmed by ATF not to meet the legal definition of a machinegun. The curved trigger blade ships in black, and because it’s purpose-built for the 10/22 platform, it installs as a direct drop-in without modifying the receiver.
