Product Overview

Duty reliability with a modern edge — the flat-shoe Duty brings frictionless certainty to working rifles.

The TriggerTech Duty Single-Stage AR (flat) pairs professional-weight reliability with the flat shoe modern training favours: a consistent, low finger position and a press that drives straight to the rear. Frictionless Release Technology keeps the duty-appropriate pull free of creep and grit, so the trigger feels controlled and deliberate rather than merely heavy — the quality that matters when the press happens under stress.

Sealed stainless internals ignore rain, dust and neglect; the fixed configuration means nothing drifts, ever. It is the duty trigger for professionals who train the modern way.

Why shooters choose the Duty Flat

Duty-weight frictionless break — controlled, never gritty
Flat shoe — modern indexing, straight press
Zero creep, zero drift — certainty under stress
Sealed stainless internals — built for working conditions
Drop-in fixed configuration — nothing to manage

Fit & installation

Drop-in fit for AR15/M4-pattern lowers with standard Mil-Spec pins; function-check before duty use.

Product Questions

Which lowers will this drop into?

It is a drop-in fit for AR-15/M4 pattern lower receivers with mil-spec trigger pins, so it swaps directly for the standard fire control group. Large-pin lowers are a different fitment, so check your receiver before ordering. Nothing needs machining or permanent modification.

What does the flat shoe change on a single-stage trigger?

The straight face pulls directly rearwards and keeps your finger in the same spot every shot, which helps consistency when you are shooting quickly. It also sits slightly lower in the guard, so it suits shooters with longer fingers or a more vertical grip. The trade-off is that it feels different from a factory trigger, so give yourself some dry practice to settle in.

How does the Duty compare with the rest of the AR range?

Duty is the hard-use, set-weight single-stage option, so there is no adjustment to check and nothing to drift. The Competitive, Adaptable and Diamond models step up to fixed competition weights or user-adjustable ranges. You can compare the options across the AR-15 triggers we stock.

What else do I need to fit it?

Nothing beyond your existing trigger pins and a small punch to drive them out and back in. Support the lower properly while you work so you do not mark the receiver, and keep the safety selector and pistol grip hardware to hand as you reassemble. Function-check the rifle unloaded, including the safety, before use.
