Franklin Armory debuted the TR-4 trigger at SOFIC 2018. This is the newest trigger to employ the patented BFSIII technology. The TR-4 is a Military and Law Enforcement specific trigger that is designed to operate with a full auto sear trip. It allows 4 selectable positions; Safe, Semi, Binary, and Full Auto.
The TR-4 gives Military and Law Enforcement agencies a more accurate, effective, and reliable trigger system that can drop into their existing platforms. Of course, the Binary mode provides significantly reduced split times between rounds, allowing for tighter double tap groups. In addition, the TR-4 incorporates the patented safety features designed into the original civilian BFSIII trigger.
The new design is easy for departments to transition to since safe, semi, and full auto are found in their traditional locations. Binary mode is found by moving the selector so that it is pointing down. This is a tremendous benefit to sworn personnel as it allows them to choose between two operating modes, semi, and Binary, with one flick of the switch.
The TR-4 also marks the first time that a pull release trigger has been employed with a machine gun sear trip. By utilizing this function in Binary mode, reliability has been guaranteed.
