Franklin Armory BFSIII HK-C1 Binary Trigger System
The Binary Firing System GEN 3 (BFSIII) represents a significant advancement in trigger technology for HK platform rifles. This 3-position trigger fundamentally changes how you can shoot your firearm.
How It Works
In position 3, the BFSIII fires one round when you pull the trigger and another round when you release it. This dual-fire capability makes it the fastest semi-automatic trigger available, dramatically reducing the time between shots and allowing you to place two separate rounds into a much tighter group.
