Geissele Automatics was established in 2004 as a manufacturer of trigger mechanisms for the AR15 rifle. Our first trigger, the Hi-Speed National Match, was designed by our Founder, Bill Geissele, for CMP and NRA Hi-Power Rifle competition.
Although designed for target shooting, the Geissele Hi-Speed trigger was found by the U.S. Military to have applications in semi-automatic sniper weapons. In 2005 Geissele Automatics received a request from the Department of Defense: "Can you build us a select-fire trigger that is as good as your Hi-Speed?" In response, Bill designed the Geissele Super Select-Fire trigger (SSF). After rigorous testing the SSF was adopted by entities in the U.S. Special Operations community and has become their trigger of choice for M4 carbine based weapons.
