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.

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.

Will this work on a smith&wesson ar-22
Jacob · Feb 28, 2025AT3 Support Team — While the TriggerTech Diamond may physically fit, it is not optimized for the M&P 15-22 due to potential light strikes. Opt for a trigger designed specifically for rimfire AR platforms to ensure reliability.

will this trigger tech single stage work in ar 10 ?
Lynn Hamlin · Feb 17, 2025AT3 Support Team — TriggerTech specifically states that their AR triggers will work in AR-10 uppers, provided the bottom of the bolt carrier is in spec. They also state that heavier bolt carriers with more inertia can make the gun more sensitive to trigger pull weight. Some AR-10 triggers have heavier springs and a heavy-duty hammer.
