Description
TriggerTech built the Duty line off feedback from military and law enforcement operators who wanted the brand's Zero Creep Technology and stainless internals but with a more tactile, service-oriented feel. This two-stage version delivers exactly that: a defined first stage of take-up, a clean wall, and a repeatable 3.5 lb break, followed by a forceful reset that lets you get back on target fast. The flat trigger shoe gives your finger a consistent, comfortable reference point and helps you feel that wall the same way every time.
What Makes the AR-10 Duty Trigger Tick
The heart of this trigger is TriggerTech's Zero Creep Technology, which uses a free-floating roller between the trigger and sear instead of two sliding surfaces. That roller takes the friction out of the equation, so the break stays crisp and predictable whether it's your first pull or your ten-thousandth. Because the system doesn't rely on polishing, coating, or lube to feel good, you get the same pull weight and the same break shot after shot.
Built to Take a Beating
The key internals are hardened 440C stainless steel for corrosion resistance and a long service life, wrapped in a tough EZAC diecast housing known for high hardness and creep resistance. The external components wear a PVD black finish, a hard coating that keeps things looking clean and shrugging off the elements. TriggerTech backs it with a lifetime product warranty, which tells you where they stand on durability.
Installing the Duty Flat Trigger
This is a self-contained cartridge-style drop-in unit, so there's no fiddling with loose springs and pins during the build. It runs standard mil-spec 0.154 inch pins (not included) and uses set screws to lock everything down snug in the lower. Do a proper function and safety check before shooting, and if you're not comfortable detail-stripping a lower, have a competent gunsmith handle the install.

Frequently Asked Questions
Is the AR-10 Duty trigger a true drop-in unit?
Yes, it's a self-contained cartridge-style drop-in, so you're not wrestling with loose springs and pins during install. It uses standard mil-spec 0.154 inch pins, which are not included, and set screws to snug it down in the lower. Always run a function and safety check before shooting.
What's the difference between the flat and curved Duty shoe?
It comes down to feel and preference. The flat shoe gives you a consistent, straight surface that helps you find the same finger placement every time and get a clean straight-back pull. The curved version feels closer to a traditional mil-spec trigger. Both use the same internals and 3.5 lb break.
How does the two-stage Duty differ from a single-stage?
The two-stage gives you a defined first stage of take-up before you hit the wall and the trigger breaks, which many operators prefer for a bit more tactile feedback and control. A single-stage is one continuous pull straight to the break. This one is a fixed 3.5 lb total pull weight.
Will this trigger work in any AR-10?
TriggerTech's AR triggers work in AR-10 platforms as long as the bottom of the bolt carrier is in spec, which most are. TriggerTech honors its lifetime warranty and satisfaction guarantee on triggers used in AR-10 rifles. If you're unsure about your specific build, a quick check with a gunsmith clears it up.
