The AR Diamond Trigger is an adjustable trigger designed to enhance the accuracy and precision of an AR for top competitors, long range shooters and enthusiasts looking to improve their shooting.

Intended Use: Long range, 3 Gun, competition, precision shooting, harsh environments, law enforcement, military, target shooting, varmint hunting.

The AR Diamond Trigger was built for top competitive shooters to offer the most accurate and dependable trigger on the market. Featuring Frictionless Release 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 0.015” tactical reset and offers outstanding reliability, even in the harshest environments. Utilizing CLKR Technology™, the pull weight is quickly and confidently adjusted from 1.5 - 4.0 lbs 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. Changing the 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.

All pull weights and measurements are approximate.

The installation guide is directed to experienced professional gunsmiths who understand the workings of their AR rifle and know how to fully detail strip the lower receiver. 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.
