TriggerTech AR15 Single-Stage Diamond Trigger
Single-Stage, 1.5lbs-4lbs, adjustable drop-in AR15 trigger
To develop a TriggerTech Single-Stage AR15 trigger we started with our proven Two-Stage AR platform that has been in the field since 2016 and combined it with a serious amount of ingenuity from our engineering department. 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.
The same Zero-Creep Technology is used in our single-stage AR triggers which is comprised of a patented, free-floating roller that is captured between the sear and the ticker. This advancement makes it possible for us to eliminate creep from every one of our triggers.
Although the TriggerTech Single-Stage AR may look very close to it Two-Stage AR counterpart, developing the Single-Stage AR was no easy task. Many factors come into play that created challenges for our engineering team. The major challenge was that our disconnect technology was originally designed to require a first stage. Eliminating any movement in the lever before the break required a completely new disconnect profile. Another advantage of the two-stage design from a manufacturing perspective is that any stack-up lever ‘slop’ is masked by the first stage. We had to revisit the processes and tolerances for all three pivots in the lever-disconnect stack to ensure a perfectly crisp first stage.
