The TriggerTech AR Diamond Single Stage Trigger Group for AR-15/LR-308 delivers precision and consistency where it matters most—at the moment of firing. Built on TriggerTech's proven Zero-Creep Technology, this single-stage trigger uses a patented free-floating roller mechanism that sits between the sear and ticker, eliminating the creep that can plague less refined designs. Whether you're running precision rifle matches, hunting at distance, or pushing accuracy at the range, a trigger engineered to break cleanly without hesitation changes everything.

Single-stage triggers appeal to shooters who prefer a direct, predictable break—no preliminary stage, no surprises. TriggerTech engineered this one to deliver that straightforward performance without sacrificing the tight tolerances that separate a quality trigger from a great one. The lever comes in your choice of curved or flat profile, letting you dial in the control style that suits your grip. With proprietary TKR (True Kinetic Release) technology managing overtravel and CLKR (Captured Lost Creep Reduction) keeping reset snappy and consistent, you get a trigger that responds the same way every single shot.

Built from 7075 aluminum and stainless steel, this trigger group is designed for serious use. It accepts hard primers, ships with an adjustable flat wire, and runs on mil-spec pins for drop-in compatibility with AR-15 and LR-308 platforms. The machining is tight: overtravel stays under 0.015" and reset under 0.030", the kind of precision that compounds into smaller groups over hundreds of rounds.

Frequently Asked Questions

What's the difference between a single-stage and two-stage AR trigger?

A single-stage trigger has one break point and fires immediately upon reaching that threshold, with no preliminary press. Two-stage triggers feature an initial takeup stage before the final break. Single-stage triggers like the AR Diamond suit shooters who want a direct, predictable release and are popular for precision rifle, competition, and hunting applications.

Will this trigger fit my AR-15 and LR-308?

Yes. The TriggerTech AR Diamond uses mil-spec 0.154" pins and is designed for both AR-15 and LR-308 platforms, providing drop-in compatibility across both caliber families.

What does Zero-Creep Technology mean, and why does it matter?

Creep is unwanted movement in the trigger lever before it actually breaks. TriggerTech's patented free-floating roller mechanism eliminates this by isolating the sear from the lever's lever stack. The result is a cleaner, more predictable break with no false starts—crucial for precision shooting where consistency drives accuracy.

What comes in the box, and what do I need to know about installation?

The trigger group includes an adjustable flat wire and ships ready to install on mil-spec AR platforms. Choose your lever profile (curved or flat) at purchase. Standard AR gunsmith installation applies; no special tools or modifications are required.
