Description
TriggerTech built this one by taking their battle-proven two-stage AR platform and figuring out how to strip the first stage right out of it. What you're left with is a single-stage trigger that breaks like a glass rod with zero perceptible creep, then snaps back on a tactical reset measured under 30 thousandths of an inch. If you've been running a gritty mil-spec trigger and wondering why your groups won't tighten up, this is the kind of upgrade that shows up on paper almost immediately.
The magic here is the Frictionless Release Technology. Instead of relying on polished, coated, or lubricated engagement surfaces that wear and change feel over time, TriggerTech uses a free-floating roller between the trigger and sear. That means shot number ten thousand feels the same as shot number one. The internals are hardened 440C stainless steel housed in a 7075 aluminum shell, so corrosion resistance and long-haul durability are baked in without any fussy maintenance.
Dialing In the Adaptable AR15 Trigger
The Adaptable model earns its name with the onboard adjustment. Using the internal set screw, you can tune pull weight anywhere from 2.5 to 5 pounds in 2-ounce increments, and you can do it with the trigger installed in the rifle. Adjusting the weight doesn't touch the hammer force either, so you get reliable primer strikes whether you've got it set light for competition or a touch heavier for a general-purpose build. The curved shoe carries a black PVD finish that looks sharp and holds up.
Where This Curved Trigger Shines
This is a natural fit for precision and competition-focused AR-15 builds where a crisp, repeatable break and fast follow-ups matter. The curved shoe gives you that familiar finger placement a lot of folks grew up shooting, so if you're not sold on flat triggers, this keeps things comfortable while still delivering serious performance. It's a self-contained drop-in unit, so it installs cleanly into a standard AR-15 lower and gets you back on the range fast.

Frequently Asked Questions
Is this AR15 single-stage trigger a drop-in unit?
Yes, it's a self-contained cassette that installs as a single unit into a standard AR-15 lower receiver. You pull your old fire control group, drop this in, and pin it in place. Plenty of folks knock the install out in a matter of minutes, though running a proper function check before live fire is always the move.
Can I adjust the pull weight without removing the trigger?
You can. The Adaptable model uses an onboard internal set screw that lets you tune pull weight from 2.5 to 5 pounds in 2-ounce increments with the trigger installed in the rifle. Adjusting the weight doesn't change the hammer force, so you keep reliable primer ignition at any setting.
What's the difference between the curved and flat version of this trigger?
The internals and performance are identical, so it comes down to feel and finger placement. The curved shoe gives you the traditional contour most shooters learned on, which a lot of people find more comfortable and intuitive. If you prefer a lower, more consistent finger position, the flat version is the way to go, but the curve is a solid choice for general and competition use alike.
Do I need anti-walk pins for this trigger?
It accepts standard AR-15 trigger and hammer pins, so you can use the pins from your existing lower. Some shooters prefer to add anti-walk pins with cassette-style triggers to keep everything locked down tight. It's a personal preference rather than a requirement for this unit to function.
