This is the curved-shoe version of TriggerTech’s top single-stage Diamond drop-in for the AR-15 — same internals as the flat, just a traditional curved trigger face for shooters who index better on a curve. The headline is the break: Frictionless Release Technology captures a free-floating roller between the sear and the trigger, so instead of two surfaces dragging past each other you get a true zero-creep release with sub-0.030″ reset and minimal over-travel.
Pull weight adjusts from 1.5 to 4.0 lbs in 2 oz increments off a single set screw, with the trigger installed, so you tune it without pulling the lower apart. Changing pull weight doesn’t change hammer force, which means dependable primer strikes whether you run it light at 1.5 lbs for a match or heavier at 3.5 for a general-purpose build — a wider usable range than most premium drop-ins.
It’s a self-contained module that drops in on mil-spec 0.154″ pins, no gunsmithing. Wear components are 440C stainless in a 7075 aluminum housing with a PVD finish, in TriggerTech’s Admiral Blue/Black colorway with a curved shoe.

Who it’s for
Precision, 3-Gun, and AR builders who want a zero-creep single-stage they can tune across a wide weight range — and who prefer the feel of a curved trigger face over a flat one.
Who should skip it
If you shoot a flat face better, grab the flat-shoe version of this same trigger instead. If you want a two-stage feel, TriggerTech makes the Diamond in two-stage. Run the light settings on a range or match gun — for a hard-use duty or defensive carbine, keep it heavy or pick a duty trigger.
