TriggerTech DutyFlat Two-Stage AR-15 Trigger - 3.5 lbs Draw Weight (AH0TDB33NNF)
- Model:
- Duty
- Material:
- Stainless Steel
The TriggerTech DutyFlat Two-Stage AR-15 Trigger is built for shooters who demand a deliberate, tactile trigger break without compromise. Born from direct feedback by military and law enforcement operators, this 3.5 lbs trigger delivers the precision engineering TriggerTech is known for—their patented Zero Creep Technology and 440C stainless steel internals—wrapped in a duty-focused design that prioritizes feedback and control over speed. The flat trigger profile and extended first stage create a more measured take-up, while the forceful tactile reset keeps you locked in for follow-up shots in close-quarter work, tactical training, or demanding hunting scenarios.
This isn't a match trigger or a hair-trigger build. The DutyFlat is purpose-built for harsh-environment reliability: it handles hard use, dusty conditions, and the unpredictability of real-world shooting. The 3.5 lbs draw weight sits heavier than competition triggers, giving you certainty that the gun won't discharge unintentionally while still breaking cleanly when you press the lever. TriggerTech's suite of proprietary technologies—Zero Creep, TKR, CLKR, and FLTWR—work together to eliminate false tactile sensations and deliver the same break every single time you press.
Standard mil-spec pin configuration means drop-in installation into any AR-15 lower receiver (though TriggerTech recommends professional gunsmith installation if you're not experienced in detail-stripping your lower). The housing is EZAC diecast, and all external stainless components are finished in PVD black—a hard, durable coating that resists corrosion and wear. Whether you're running three-gun, hunting varmints, or training for duty use, the DutyFlat gives you a trigger that responds the same way in any light, temperature, or condition.

Frequently Asked Questions
Will this trigger fit my AR-15 lower receiver?
Yes. The TriggerTech DutyFlat uses standard mil-spec pins (0.154 inch) and is compatible with all AR-15 platforms. Note that trigger pins are not included with this trigger. Professional installation by a gunsmith is recommended if you're not experienced in detail-stripping your lower receiver.
Is this trigger suitable for duty or tactical use?
Yes. The DutyFlat Two-Stage was specifically designed in collaboration with military and law enforcement operators. The 3.5 lbs draw weight, extended first stage, and forceful tactile reset are engineered for reliability in harsh environments, close-quarter engagement, and tactical operations—while TriggerTech's Zero Creep Technology ensures the break remains crisp and predictable under any condition.
What's the difference between the flat lever and a curved lever?
The TriggerTech DutyFlat uses a flat, straight trigger lever profile. This design choice provides different ergonomics and trigger control feedback compared to a traditional curved lever. Both are available in the Duty Line; the flat option is favored by many shooters for consistency and positive control.
What comes in the box?
The package includes the trigger assembly itself. Trigger pins and an installation guide are not included. TriggerTech's installation guide is directed toward experienced gunsmiths; if you lack detailed AR-15 lower receiver experience, professional gunsmith installation is strongly recommended.
