TriggerTech DiamondPro Adjustable Curved Single-Stage AR-15 Trigger (1.5-4.0 lbs)

The TriggerTech DiamondPro Adjustable Curved Single-Stage AR-15 trigger brings match-grade precision to your rifle without the complexity of a two-stage design. Built for shooters who demand a clean, predictable break with zero creep, this curved trigger combines TriggerTech's patented Zero-Creep Technology with user-adjustable pull weight—all in a single-stage package that keeps your shots fast and repeatable. Whether you're running precision rifle matches, hunting, or pushing distance at the range, a quality AR trigger is the foundation of consistent accuracy.

The engineering behind this trigger is substantial. TriggerTech's Zero-Creep Technology uses a free-floating roller captured between the sear and ticker, eliminating the mushy pre-break movement that plagues standard triggers. Because there's no first stage to hide mechanical slop, every pivot and tolerance in the lever-disconnect stack had to be redesigned and refined to deliver that crisp, immediate trigger response you feel the moment you touch the shoe. Pull weight is user-adjustable from 1.5 to 4.0 lbs, so you can dial in exactly what your shooting demands.

The DiamondPro is built tough: 7075 aluminum and stainless steel construction, mil-spec pin diameter, and a flat wire design that's hard-primer compatible for reliability with all ammunition. Overtravel is kept sub-0.015" and reset to sub-0.030", minimizing wasted motion and keeping your trigger ready for the next shot. The curved lever profile fits naturally under your finger for a familiar, controllable feel.

This is a purpose-built trigger for AR-15 shooters who refuse compromise—competition shooters, long-range hunters, and serious practitioners who understand that trigger quality compounds throughout the day. Drop it in a mil-spec lower receiver and experience what precision feels like.

What makes this trigger different from a standard two-stage AR trigger?

The TriggerTech DiamondPro is a single-stage design with zero creep, meaning there's no mushy pre-break movement—the trigger goes straight to the break. Its free-floating roller technology eliminates creep entirely, and because there's no first stage to hide mechanical tolerances, every component had to be engineered to tighter standards for a crisp, clean feel.

Is this trigger compatible with hard primers?

Yes. The flat wire design is hard-primer compatible, making it reliable across all ammunition types.
