TriggerTech Diamond 1.5-4LB Trigger Flat and Curved

The TriggerTech AR15 Single-Stage drop-in AR trigger provides a clean break with extremely short overtravel and reset. This trigger upgrade achieves a smooth pull while maintaining reliability and durability of a mil-spec AR-15 trigger. The pull weight is quickly adjusted in 2 OZ increments from a set screw with the trigger installed. Find what trigger pull weight works for you as low as 1.5LB and up to 4.0LB.

Most shooters note that the pull weights feeling around 0.5 LBs lighter than a traditional friction based trigger of the same measured pull weight. This trigger bears the adaptable name because changing its pull weight does not affect hammer force so you get dependable primer strikes at every weight. Upgrade your AR with a TriggerTech trigger and gain the confidence to achieve reliable accuracy with ease.

Better than Timney

I have built several AR-Precision rifles and always used reduced pull drop-in triggers.
My favorite used to be Timney, especially Calvin Elite. This TriggerTech is the second one I have used for my last 2 builds. Timney is nice....TriggerTech is better made, smoother and more precise. I also prefer the TT adjustment style.

Thanks for the review! We're glad to hear that you're happy with the TriggerTech Diamond Single Stage AR-15 Trigger.
