The TriggerTech Duty is a single-stage drop-in trigger with a flat shoe for AR-15 and M4 pattern rifles.
Hard-use reliability with a modern edge — the flat-shoe Duty brings frictionless certainty to working rifles.
The TriggerTech Duty Single-Stage AR (flat) pairs a robust pull weight with the flat shoe modern training favours: a consistent, low finger position and a press that drives straight to the rear. Frictionless Release Technology is what TriggerTech credits for keeping that heavier pull free of creep and grit, so the trigger feels controlled and deliberate rather than merely heavy.
Sealed stainless internals handle rain, dust and neglect; the fixed configuration means nothing to set. It is the hard-use trigger for shooters who train the modern way.
Why shooters choose the Duty Flat
-
Robust frictionless break — controlled, never gritty
-
Flat shoe — modern indexing, straight press
-
Nothing to adjust — certainty under pressure
-
Drop-in fixed configuration — nothing to manage
What the Duty Flat fits
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 with a flat shoe suits a rifle shot in gloves and in poor weather. Confirm your pin size before ordering. Function-check the rifle before live fire.
