Featuring Frictionless Release Technology™, this drop-in AR trigger for firearms that use AR-15 triggers has a short, two-stage action, designed to feel like a 1911 trigger, that provides a true zero-creep break, extremely short overtravel, a sub 0.030” tactical reset and offers outstanding reliability, even in the harshest environments. Utilizing CLKR Technology™, the pull weight is quickly and confidently be adjusted in 2oz increments from a set screw with the trigger installed. Due to there being truly zero creep, most shooters report the pull weights feeling ~0.5lbs lighter than a 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. Frictionless Release Technology™, along with hardened 440C stainless steel internal components ensure corrosion resistance and an extended service life. As Frictionless Release Technology™ does not rely on coating, polishing or lubricating the key engagement surfaces, trigger pulls will be more consistent from shot to shot and after thousands of shots than you ever thought possible.

Additional Information:

Frictionless Release Technology™

TriggerTech developed FRT™ to get away from the limitations faced by sliding friction triggers (all other triggers are sliding friction triggers). FRT™ is comprised of a patented, free-floating roller that is captured between the sear and the trigger. This advancement makes it possible for us to engineer the ideal release characteristics into every one of our triggers.

TKR Technology™

TriggerTech set out to develop a trigger with leading overtravel and reset control and developed a new component to achieve this. TKR Technology™ utilizes something we’ve named the “ticker” – an intermediary component that can pivot freely from trigger lever to enable the sear to release without requiring further displacement from the trigger lever. This minimizes overtravel and sets you up for the perfect reset – one that is short (< 0.030″) but remains tactile and forceful enough so you are not wondering if your next shot is good to go.

CLKR Technology™

TriggerTech wanted to make adjustable triggers that allowed the operator to quickly and confidently adjust pull weight. This drove the development of CLKR Technology™ – a detent and set screw combination that enables the operator to adjust the trigger’s pull weight with tactile clicks that let the operator know just how much they have adjusted. To further adjusting confidence, we made the adjustment feature fail-safe. It’s designed to withstand over tightening and if the set screw is removed the trigger will operate at the low end of its pull range.

FLTWR Spring Technology™

High performance AR triggers often have a reputation for failing to consistently deliver sufficient hammer strikes. To ensure TriggerTech was not type-cast we developed FLTWR Spring Technology™. FLTWR Spring Technology™ is simply a flat wire hammer spring that enables us to get more coils and provide more force into the hammer. This innovation results in more dependable primer ignition, less variability in bullet velocity and a longer service life for your trigger.

TriggerTech Levers

The trigger lever is where you connect with your firearm and we believe it should be perfect. Our curved triggers have that perfect amount of bend and the vertical grooves are there to help keep your finger in place. Our straight levers offer a different feel and enable operators to comfortably adjust trigger pull weight by moving their finger up or down on the lever. The edges are neither round nor sharp enabling control without discomfort. The locator nub is large enough to be noticed yet minimalist enough that it is possible to effectively operate even with your finger over this point.

TriggerTech Housings

TriggerTech housings are made of anodized 7075 aluminum. They are designed to minimize the ability for contaminants to get inside the trigger.

Even when intentionally contaminated with the harshest materials, Frictionless Release Technology™ and TKR Technology™ work together to keep your gun running with incredibly crisp trigger breaks.

Zero Creep

The Dvorak TriggerScan™ System is a computer controlled, motorized instrument, specifically designed to test trigger mechanisms of firearms. The system provides precise and repeatable graphical evidence of trigger quality. The patented technology sets a new standard in trigger quality evaluation. The Dvorak TriggerScan™ provides empirical evidence that Frictionless Release Technology™ enables TriggerTech to achieve a true zero-creep release.
