Franklin Armory BFSIII AK-C1 Binary Firing System for most AK platforms - Curved Trigger
Product Details
The Franklin Armory BFSIII AK-C1 is a drop-in binary trigger built for most AK-47 platform rifles. This trigger was designed to put rounds downrange faster than any conventional semi-automatic trigger can. The GEN 3 version of Franklin Armory's Binary Firing System this three-position trigger in its third position fires one round on the pull and a second round on the release. That single design choice is what makes the BFSIII the fastest semi-automatic trigger on the market delivering dramatically reduced split times between rounds and tighter groups.
The enhanced control sets the AK-C1 apart from a standard trigger swap. The trigger runs a single-stage curved design with a 5.5 lb pull weight so the feel stays crisp and predictable across all three positions. Position one is safe position two is standard semi-automatic and position three activates binary mode. If you decide that you don't want the release round to fire Franklin Armory's Patent Pending selector lets you cancel it by switching out of binary mode mid-string. A positive reset on the release phase keeps the cycle consistent shot after shot making it perfect for tactical and competition shooters when speed and repeatability matter.
Built from steel and finished in black the AK-C1 is an easily installed upgrade for AK-pattern rifles making it a straightforward path to a serious performance gain without much gunsmithing. It carries Franklin Armory's manufacturer product number 03-50000-BLK and UPC 818725011863 so you can confirm you're getting the correct AK-specific unit rather than a platform-mismatched trigger.
