Product Description

The TriggerTech AR-10 Diamond Two-Stage Flat Trigger (ART-TRB-14-NNF) is a precision drop-in fire control unit engineered specifically for long-range, competition, and tactical AR-10 (.308 Win / 6.5 Creedmoor) rifle platforms. Designed around TriggerTech's patented Zero Creep Technology™, this trigger utilizes a free-floating roller between the sear and the trigger body. This design eliminates sliding friction, delivering a glass-smooth break without creep or degradation over thousands of firing cycles.

Featuring CLKR Technology™, the Diamond Two-Stage offers externally adjustable pull weight ranging from 1.5 lbs to 4.0 lbs via a detented click-adjuster screw. The first stage is factory set to a light 0.25 lbs, providing a clean take-up before stopping firmly at a crisp wall. The second stage breaks cleanly between 1.25 lbs and 3.75 lbs with sub-0.015" overtravel and an exceptionally short sub-0.030" tactile reset, allowing for ultra-fast, controlled follow-up shots on target.

Housed in an anodized 7075-T6 aluminum body with hardened 440C stainless steel internal components, the ART-TRB-14-NNF is built to withstand heavy recoil forces while maintaining full-force hammer strikes across commercial and hard-primer military ammunition. The flat-face PVD black trigger lever provides enhanced tactile feedback and geometric leverage, ensuring consistent finger placement and superior shot-to-shot mechanical control.

*Armorer Bench Notes & Real-World Staging Guidance:*

Fitment Matrix: Direct drop-in fitment for standard MIL-SPEC AR-10, LR-308, and SR-25 lower receivers using standard 0.154" trigger pins. (Designed specifically for AR-10 bolt carrier group dimensions and recoil profiles; do not install in AR-15 platforms).

1. Ensure firearm is completely unloaded, remove existing AR-10 trigger assembly and safety selector lever.
2. Drop the self-contained TriggerTech Diamond cassette into the lower receiver trigger well and align pin holes.
3. Insert standard 0.154" MIL-SPEC trigger pins through lower receiver and cassette body.
4. Tighten the two integrated bottom set screws using an Allen wrench to lock the cassette firmly against the receiver pins, eliminating lateral slop.
5. Reinstall safety selector, perform complete safety and function checks, and adjust pull weight externally using the CLKR detented set screw.
