The Franklin Armory BFSIII AK-C1 is a binary trigger for the AK platform (brand part no. 03-50000-BLK). Franklin Armory designed it for most standard-caliber AKs in 7.62×39, 5.45×39 and 5.56 NATO. The Binary Firing System Gen 3 is a three-position trigger: Safe, Semi, and Binary, where it fires one round on the pull and one on the release. Franklin Armory points it at tactical and competition shooters, and says the system provides greatly reduced split times between rounds.
