Triggertech Special Edition AR15 Competitive Independence Trigger Black/White. While it was initially viewed as not possible our team of engineers developed a solution that allowed us to eliminate the need for a first-stage within our two-stage. The result has all of us at TriggerTech scratching our heads - we always felt that the unique combination of a short first stage true Zero-Creep break extremely short over travel and the ability to reset on the 2nd stage made our Two-Stage the perfect AR15 trigger. Now that we have our fingers on the only true Zero-Creep Single-Stage AR trigger we are all in agreement the new TriggerTech Single-Stage AR15 is our new go-to for most applications.
