Product Overview and Introduction

Experience exceptional reliability, flat-bow ergonomics, and crisp control with the TriggerTech Duty Two-Stage Drop-In Trigger featuring a match-grade Flat Bow and a fixed 3.5 lb Pull Weight – MPN: AHT-SDB-33-NNF. Engineered specifically for duty, defense, and high-volume tactical shooting on AR-15 and AR-10 platforms, the Duty series brings TriggerTech’s renowned Frictionless Release Technology® (FRT) into a rugged, non-adjustable package designed to withstand rigorous operational environments.

Whether you are equipping a patrol rifle, setting up a home-defense carbine, or building a hard-use tactical gas gun, the TriggerTech Duty Flat delivers a clean, zero-creep break and a positive reset that enhances your shooting confidence under pressure.

Frictionless Release Technology® and Flat Bow Ergonomics

Built to bridge the gap between match-grade precision and bombproof duty reliability, the Duty Flat trigger incorporates advanced internal mechanics and superior user-interface design:

• Frictionless Release Technology® (FRT): Delivers a crisp, glass-rod break with zero creep and absolute repeatability by eliminating sliding friction between internal components.

• Flat Match Bow Design: The flat trigger face provides a consistent, repeatable finger placement surface, offering enhanced leverage and a comfortable, straight-back pull that makes the 3.5 lb weight feel exceptionally light and direct.

• Predictable Two-Stage Action: Features a smooth first-stage take-up followed by an ultra-clean second-stage break, set to a consistent, safe total pull weight of 3.5 pounds.

• Short, Tactile Reset: Engineered with an exceptionally short and distinct reset to support rapid, controlled follow-up shots.

• Tough Non-Adjustable Design: Factory-fixed pull weight ensures that settings cannot shift or back out under heavy recoil or harsh operational conditions.

Drop-In Convenience and Robust Construction

The TriggerTech Duty Flat trigger is housed in a robust, self-contained aluminum cassette that drops seamlessly into standard small-pin AR-15 and AR-10 lower receivers. It utilizes hardened 440C stainless steel internal components for maximum corrosion resistance and longevity, ensuring flawless performance in the field.
