TriggerTech built the Duty line to be their take on what mil-spec should have been all along. This 5.5 lb two-stage version pairs a curved trigger shoe with the same 440C stainless steel internals found in their higher-end triggers, so you get a serious performance jump over a standard mil-spec trigger without moving into match-trigger territory. It drops right into any standard AR-15 lower and uses the usual .154-inch trigger pins, which makes swapping it in about as painless as trigger installs get.
The whole Duty concept came straight out of feedback from active military and LE operators who wanted more feel than a light competition trigger gives you. To get there, TriggerTech lengthened and weighted the first stage, then engineered a more forceful reset on the back end. The result is a trigger you can run with gloves, under stress, or in the cold and still know exactly when it's about to break. That longer take-up leading into a defined wall is a big part of why this one feels so confidence-inspiring on a working gun.
The heart of it is TriggerTech's patented Zero Creep Technology, which uses a roller between the sear and the trigger instead of the sliding friction you get in a traditional setup. That roller wipes out the mushy drag, so the break stays crisp and consistent shot after shot, even thousands of rounds down the road. The internals are hardened 440C stainless for corrosion resistance and long service life, the housing is EZAC diecast for durability, and the external stainless components wear a black PVD coating that looks clean and holds up.
That 5.5 lb pull weight lands in a great spot for a defensive carbine, patrol rifle, or a general-purpose build where you want a little more resistance than a 3.5 lb trigger. It's also right at home for 3-Gun, varmint work, and range days. If you like a curved shoe and a two-stage feel with a real wall to press against, this is the Duty trigger to grab.
Yes, it's a self-contained cartridge-style unit that drops into any standard AR-15 lower receiver. It uses the usual .154-inch mil-spec trigger pins, so most folks with basic gunsmithing know-how can install it quickly. If you're not comfortable working inside a lower, it's worth having a competent gunsmith handle the install and safety checks.
The two-stage version gives you a defined first stage of take-up before you hit the wall, then a clean break. The single-stage is one continuous press with no take-up. The two-stage feel is popular for defensive and duty use because that first stage acts as a built-in safety cue before the shot breaks.
No, the Duty two-stage is set at a fixed 5.5 lb and isn't user-adjustable. That's by design, since operators asked for a rugged, no-fuss trigger with nothing to tune or loosen up over time. If you want an adjustable pull weight, TriggerTech's Adaptable or Diamond lines are the ones to look at.
Instead of the sliding friction found in a standard trigger, it uses a roller between the sear and the trigger. That eliminates the mushy drag and creep you feel in a mil-spec trigger, giving you a crisp, repeatable break. It also stays consistent over thousands of rounds since it doesn't rely on polishing or coatings that wear down.
