Description
TriggerTech built the Duty line around a simple ask from the people who carry rifles for a living. Military and law enforcement operators wanted the brand's Zero Creep feel and proven stainless steel internals, but with a more tactile, positive break and a reset you can genuinely feel. This AR-10 model answers that with a fixed 3.5 lb single-stage pull that breaks clean and cycles the same way shot after shot. It's a cartridge-style unit that drops right into your AR-10 or LR-308 lower, so you're not fussing with loose hammers, sears, and springs during install.
What Sets the AR-10 Duty Trigger Apart
The heart of this thing is Zero Creep Technology, which doesn't lean on polishing, coating, or lubing the engagement surfaces to feel good. That means the break stays consistent from your first round through thousands more down the road. The flat trigger shoe gives you a repeatable finger index and a straight-back pull, which a lot of folks find helps their trigger control on longer shots. Reviewers routinely describe the break as short and crisp with no grit, and the reset comes back with a firm, audible character that suits a working rifle.
Living With the Duty on Your AR-10
At 3.5 lb it lands in a sweet spot that's light enough for precise work at distance but still has enough weight to feel deliberate under stress. Owners running it in Aero M5, PSA PA-10, and similar .308 pattern lowers report flawless function and a night-and-day improvement over factory triggers. The housing uses a die-cast frame paired with the same style of precision internals found in TriggerTech's pricier triggers, which is a big part of why this trigger punches so far above its price point.
Installing the AR-10 Duty Trigger
Installation is straightforward for anyone comfortable working inside their lower receiver. It goes in as a self-contained cassette and snugs down with the included hex hardware. Worth noting up front: this trigger does not ship with anti-walk or anti-rotation pins, so plan to reuse your existing pins or grab a set separately if you prefer them. If detail-stripping a lower isn't your thing, a competent gunsmith can knock this out quickly.

Frequently Asked Questions
Is the AR-10 Duty Trigger a true drop-in unit?
Yes. It's a self-contained cartridge-style trigger that drops into your AR-10 or LR-308 lower as one piece, so there's no fitting individual hammers, sears, or springs. Most owners report a quick, straightforward install as long as you're comfortable working inside a lower receiver.
Does this trigger come with anti-walk pins?
No, the Duty Trigger does not include trigger and hammer pins. It ships with the hex keys needed for the rear snug-down screws, so you'll reuse your existing pins or pick up a dedicated set if you prefer anti-walk or anti-rotation pins.
What's the difference between the single-stage and two-stage AR-10 Duty Trigger?
The single-stage version is one continuous pull that breaks cleanly with essentially no take-up. The two-stage gives you some light take-up before hitting a defined wall, then breaks. It comes down to personal preference and how you like to run your rifle.
Will the flat 3.5 lb pull work for both precision and defensive use?
It's a good middle ground. At 3.5 lb the pull is light enough for accurate work at distance yet deliberate enough to feel confident under pressure, which is exactly what the Duty line was designed around based on operator feedback. The flat shoe also helps with a consistent finger index for straight-back trigger control.
