The TriggerTech Duty is a single-stage drop-in trigger with a curved shoe for AR-15 and M4 pattern rifles.
Built for rifles that work for a living — the TriggerTech Duty is frictionless performance at a practical weight.
The TriggerTech Duty Single-Stage AR (curved) applies Frictionless Release Technology to a harder-use brief: a pull weight in the practical range, a clean break and an ultra-short reset, wrapped in the reliability standards a working rifle demands. The frictionless design means a heavier, more forgiving weight still feels clean and controlled rather than gritty — exactly the compromise conventional triggers never solved.
The curved shoe keeps the familiar feel trained hands expect, and sealed stainless internals mean the same pull through rain, mud and thousands of drills. Drop-in fit, no tuning, nothing to set.
Drop-in fit for AR-15/M4 pattern lower receivers with standard Mil-Spec trigger pins, which includes UK straight-pull AR-15 builds — a fixed, forgiving weight and a curved shoe make this a sensible choice for a rifle shot in gloves and in poor weather. Confirm your pin size before ordering. Function-check the rifle before live fire.

Yes - it is a drop-in single-stage unit for AR-15/M4 pattern lowers with mil-spec trigger pins, using your existing pins and no permanent alteration. The only real check is pin size, since large-pin receivers are not the same fitment. Confirm which your lower uses before ordering.
Duty is TriggerTech's hard-use single-stage option, put together for general shooting and defensive-style rifles rather than bench work. It is the most affordable way into the brand's AR triggers here, and it keeps the same drop-in fitment as the dearer models. If you want an adjustable weight instead, look at the Adaptable or Diamond models.
The Duty is supplied as a set-weight single-stage trigger and the specification does not list an adjustment range, so treat it as fixed rather than something to dial in. There is also a Mil-Spec weight version of the Duty if you need a heavier, service-standard pull. Ask us before ordering if a particular weight matters to you.
This is the curved-shoe version, which matches the finger position most shooters already have from a standard mil-spec trigger. The <a href="/products/triggertech-duty-single-stage-flat-ar-15">flat-shoe Duty single-stage</a> is the same trigger with a straight face if you prefer a lower, more consistent contact point. Both are black and need nothing more than your existing trigger pins.
It goes out from the United Kingdom with £5 tracked UK delivery in 7–10 business days, and tracking is emailed to you when it ships. If the trigger is the wrong fit for your lower, see our returns policy or <a href="/pages/contact">contact us</a> and we'll help sort it.
