To develop a TriggerTech Single-Stage AR15 trigger they started with their proven Two-Stage AR platform that has been in the field since 2016 and combined it with a serious amount of ingenuity from their engineering department. While it was initially viewed as not possible TriggerTech's team of engineers developed a solution that allowed them to eliminate the need for a first-stage within their two-stage. The result has everyone at TriggerTech scratching their heads - they 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 their Two-Stage the perfect AR15 trigger. Now that they have our fingers on the only true Zero-Creep Single-Stage AR trigger they are all in agreement - the new TriggerTech Single-Stage AR15 is the new go-to for most applications.
