The TriggerTech DutyFlat Single-Stage Trigger for AR-9 is built for shooters who demand reliability in real-world conditions. Where competition-focused triggers prioritize speed, the Duty line was engineered from feedback by military and law enforcement professionals who operate in harsh environments and close-quarters scenarios. This straight-flat single-stage trigger delivers a crisp 3.5-pound break with zero creep, giving you the consistency you need when precision matters. Whether you're running duty drills, three-gun matches, or varmint hunting, the DutyFlat's robust design and proprietary construction are engineered to outlast punishing use without compromise.

What sets this trigger apart is its purposeful design philosophy. TriggerTech listened to operators in the field and built a heavier, more forceful reset compared to their Performance line—ideal for the deliberate control needed in tactical work and close-range engagements. The DutyFlat's flat profile reduces felt creep and delivers that confident break you feel immediately when the sear breaks, shot after shot. It's the kind of trigger that makes you trust your firearm when reliability is non-negotiable.

Built with TriggerTech's proprietary Zero Creep Technology, backed by CLKR and FLTWR engineering, this AR-9 trigger comes ready to install and perform. The single-stage design keeps things simple and fast—no two-stage complication, just a clean, predictable release. If you're building or upgrading an AR-9 for duty use, 3-gun competition, or serious field work, this trigger rewards disciplined technique with consistent results.
