Franklin Binary Trigger

An AR-15 binary trigger is a unique trigger mechanism that fires one round when the trigger is pulled and another when it is released. This creates a faster, more responsive firing rhythm without making the rifle fully automatic, since each shot still requires a separate mechanical action. The design uses natural finger movement to increase firing efficiency, offering an engaging and rhythmic shooting experience. Enthusiasts study binary triggers—often using systems like the Franklin Binary Trigger for reference—because they demonstrate innovative mechanical engineering while maintaining full user control. Although they feel fast, they remain distinct from both semi-auto and full-auto trigger systems, emphasizing safety, awareness, and deliberate trigger discipline.
