Featuring Zero Creep Technology, 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. Pull weight of 3.5 lbs CLKR Technology Available with curved or flat trigger 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. Zero Creep Technology, along with hardened 440C stainless steel internal components ensure corrosion resistance and an extended service life. As Zero Creaap 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. 1st Stage Pull Weight - 0.75 lbs 2nd Stage Pull Weight - 2.75 lbs Total Pull Weight - 3.5 lbs All pull weights and measurements are approximate.

If you do not have these skills, we strongly suggest you retain the services of a competent professional gunsmith to install your trigger, and perform all important safety checks.
