Franklin Armory BFSIII AK-C1 Binary Trigger for AK Platforms

The Franklin Armory BFSIII AK-C1 (brand part no. 03-50000-BLK) brings Franklin Armory’s Binary Firing System to most standard-caliber AK platforms, giving shooters a curved, 3-position trigger that switches between Safe, Semi, and Binary modes. In Safe, the trigger won’t fire; in Semi, it fires one round per pull just like a standard AK trigger; and in Binary, it fires one round on the pull and a second round on the release, cutting split times between shots for tighter, faster groups. The release round can be canceled at any time by simply moving the selector out of Binary mode while the trigger is still held back, giving the shooter full control over which mode is active. The trigger housing measures approximately 9 inches, and Franklin Armory built the AK-C1 to install without a gunsmith, requiring no proprietary bolt carrier group to function. It’s compatible with most standard-caliber AK platforms running 7.62×39, 5.45×39, or 5.56 NATO, and it’s built for AK owners who want the speed of Franklin Armory’s Binary Firing System without leaving the AK platform.
