The most critical point of contact between the rifle and the shooters is the trigger. Pulling the trigger is the last act necessary to send a round downrange, and the slightest movement can disrupt the round's trajectory.
Geissele Automatics looked at Mil-Spec AR-15 triggers and realized that a long, heavy, and gritty trigger pull is not conducive to accurate shooting.
Under the leadership of Bill Geissele, Geissele Automatics set out to build a trigger that solved this issue, specifically targeting precision shooters in CMP and the NRA Hi-Power Rifle competitions.
First, they developed the Hi-Speed National Match trigger in 2004, which paved the way for them to design triggers for law enforcement, United States Military, and civilians.
They have since designed handguards, scope mounts, and more for competitors and military customers.
