TriggerTech Diamond AR-15 Flat Single-Stage Trigger 1.5-4.0 lbs Adjustable - Black PVD

The TriggerTech Diamond is a premium flat single-stage trigger drop-in upgrade for the AR-15 platform. As TriggerTech's top-tier Diamond model, it incorporates the company's patented Zero-Creep Technology for a crisp, consistent break with no perceptible creep before release.

Pull weight is fully adjustable from 1.5 to 4.0 lbs, allowing the shooter to dial in a light competition-grade break or a slightly heavier tactical pull without swapping springs. The trigger shoe and hammer are finished in a Black PVD coating for excellent wear and corrosion resistance, while the internal components are machined from hardened 440C stainless steel for long-term durability under hard use.

Designed as a true drop-in assembly, the unit installs into any standard Mil-Spec 0.154" AR-15 lower (pins are not included). It also features short overtravel and a sub-0.030" tactical reset for fast, repeatable follow-up shots in 3-Gun, competition, law enforcement, military, and defensive applications.
