TriggerTech AR Diamond Two-Stage Flat Bow Trigger Group for AR-15/LR-308 - Black

The TriggerTech AR Diamond two-stage flat bow trigger group is a drop-in replacement trigger engineered for shooters who demand crisp, predictable breaks and rock-solid reliability across competition, hunting, and defensive use. Built for AR-15 and LR-308 platforms, this black PVD-coated trigger combines match-grade precision with the short, clean pull weight that serious riflemen expect from a fighting firearm.

What sets the Diamond apart is its Frictionless Release Technology—a design philosophy that eliminates the friction, creep, and inconsistency baked into traditional triggers. The result is a true zero-creep break followed by extremely short overtravel and a sub-0.030-second tactical reset. Most shooters report the pull feeling roughly half a pound lighter than comparably weighted friction-based triggers, which means faster, more confident trigger control without requiring a heavier pull weight. The two-stage action is tuned to mimic the feel of a 1911, delivering the positive separation between take-up and break that competitive shooters and precision hunters value.

The Diamond's construction—7075 aluminum housing with hardened 440C stainless steel internals, all finished in durable PVD black coating—is built to function in harsh conditions without maintenance. Frictionless Release Technology means you're not relying on lubrication or polishing to keep breaks consistent; shot-to-shot consistency remains tight even after thousands of rounds. Pull weight is field-adjustable via the CLKR Technology set screw in 2oz increments without affecting hammer strike force, so you can dial in the weight that suits your application while keeping reliable primer ignition across the board.

Professional installation by a gunsmith experienced with AR lower receivers is strongly recommended. Standard mil-spec trigger pins are required but not included.

Frequently Asked Questions

What AR platforms does this trigger fit?

The TriggerTech AR Diamond is compatible with AR-15, LR-308, and pump action AR rifles that use standard mil-spec trigger pins (sold separately). Installation requires detail stripping the lower receiver and should be performed by an experienced gunsmith.

What does zero creep mean, and why does it matter?

Zero creep means there is no perceptible movement or friction in the trigger before the break occurs. With traditional triggers, you take up slack before the sear trips; with the Diamond, the pull is immediate and predictable. This allows faster target acquisition and more consistent shot placement, especially critical in competition and precision hunting.

Can I adjust the pull weight myself?

Yes. The CLKR Technology set screw allows you to adjust pull weight in 2oz increments while the trigger is installed in your rifle. Importantly, changing pull weight does not reduce hammer strike force, so you maintain reliable primer ignition across all weight settings.

Are trigger pins included?

No. Standard mil-spec trigger pins (0.154") are required but not included. You will need to source these separately or use pins from your original trigger assembly if compatible.
