Featuring Frictionless Release Technology(TM), this drop-in AR trigger 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(TM), 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(TM), along with hardened 440C stainless steel internal components ensure corrosion resistance and an extended service life. As Frictionless Release Technology(TM) 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.
