I installed the Triggertech Duty Single-Stage Trigger in my AR-15 a few weeks ago, and I’m blown away by how much it has improved my shooting experience. The break is incredibly crisp with absolutely zero creep — it feels like snapping a glass rod ev...

Great trigger at a good value! by Jason, Verified Owner, April 11, 2025
These triggers have a nice break and reset. I have two, one in an AR15 and one in a LR308 and both run great. As others have mentioned, the reset seems at least as good, if not better, than the Competition and the Diamond models (I have both as well)...

Product Info for Triggertech Duty AR15 Single-Stage Trigger

The design of our new Duty Line was driven by feedback from military and law enforcement operators. They wanted our patented Zero Creep Technology and proven stainless steel internals, but with a more tactile feel. To achieve this, we more than doubled the pull weight and length of the first stage. And after the zero creep break we engineered a much more forceful reset. The result? A totally different feel that offers more certainty with every shot. The Duty Line is TriggerTechs interpretation of what Mil-Spec should be. The AR Duty line is the latest in TriggerTech triggers that offers robust reliability without compromising performance. Inspired by active MIL / LE Operators these triggers offer a longer take up (on two-stages) and a more forceful reset.image

Warning: All pull weights and measurements are approximate. The installation guide is directed to experienced professional gunsmiths who understand the workings of their AR rifle and know how to fully detail strip the lower receiver. If you do not have these skills, we strongly suggest you retain the services of a competent professional gunsmith to install your trigger, and perform all important safety checks.
