TriggerTech AR15 Duty / Mil-Spec Trigger – 5.5lb

Available in Single or Two-stage, 5.5 lb fixed pull, drop-in AR15 trigger

Triggertech is known for amazing triggers for bolt guns and AR-style rifles.  They have expanded the lineup to include new AR Duty drop-in triggers with a great feel and a clean break.

The AR15 Mil-Spec Duty triggers were developed in response to law enforcement and military requests for a trigger with a lower price point and a heavier first stage that still carried the Triggertech feel and quality.

The Mil-Spec Duty triggers are a fixed pull weight of 5.5 lbs and have slightly more overtravel and reset but retain a zero creep takeup. The Mil-Spec / Duty triggers are offered in single- or two-stage designs and feature a diecast housing with 440C stainless steel internal components.

As Mil/LE operators adopted our AR line, the feedback was clear:

What They Loved

  • Reliability; confident in the trigger’s performance, even in the harshest environments
  • Trigger Break; Zero Creep Technology creates a crisp break every time
  • Service Life; proprietary design outlasts the competition

What They Asked For

  • Longer and Heavier first-stage
  • Heavier reset force
  • Cost-sensitive price point

Intended Use

Close quarter engagement,  harsh environments operations,  law enforcement, military,  3 Gun,  varmint hunting.

The AR Duty line is the latest in TriggerTech triggers that offer 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.

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 necessary safety checks.
