TriggerTech Duty Two-Stage Curved Trigger 5.5lb AR-15 Mil-Spec

The TriggerTech AH0TDB55NNC Duty trigger delivers precision two-stage control with a clean 5.5-pound break for AR-15 platforms. This mil-spec compatible trigger system eliminates creep and overtravel while maintaining the reliability standards demanded by professional users.

What Makes This Different

TriggerTech's Zero-Creep Technology uses a proprietary roller and sear design that creates a glass-smooth break without the friction found in traditional triggers. The two-stage configuration provides a distinct wall before break, allowing shooters to stage their shots with confidence. Independent testing shows consistent break weights within 0.1 pounds across thousands of cycles, compared to factory triggers that can vary by 1-2 pounds.

Key Features

• Zero-Creep Technology eliminates friction for consistent break feel
• Two-stage design with 3.5lb first stage, 2lb second stage (5.5lb total)
• Curved trigger bow matches standard AR-15 ergonomics
• Drop-in installation fits all mil-spec AR-15 lower receivers
• Hardened steel construction with nickel-boron coating
• Self-contained cassette design prevents contamination
• Adjustable overtravel screw for fine-tuning

Field testing demonstrates consistent performance across temperature ranges from -40°F to 140°F without timing changes. The sealed trigger cassette prevents debris infiltration during extended use in harsh environments. Competition shooters report improved accuracy at 300+ yards due to the predictable break characteristics, while duty users appreciate the safety margin provided by the two-stage pull.
