Product Info for Triggertech Adaptable Sig MPX Two-Stage Trigger

TriggerTech has developed and finely tuned three Pistol Caliber Carbine triggers to enhance the accuracy and precision of your rifle. Each model has unique specs and features designed for their specific platform.image

Intended Use: Competition, precision shooting, harsh environments, law enforcement, target shooting.

The SIG MPX trigger features a bumper in the housing that transfers the majority of the blow back energy to the lower receiver. This was designed with safety in mind and helps to protect the trigger.

Our Pistol Caliber Carbine Triggers are built for top competitive shooters to offer the most accurate and dependable trigger on the market. Featuring Zero Creep Technologyâ„¢, this drop-in 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 Technologyâ„¢, the pull weight is quickly and confidently 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. Changing the pull weight does not affect hammer force so you get dependable primer strikes at every weight. Frictionless Release Technologyâ„¢, along with hardened 440C stainless steel internal components ensure corrosion resistance and an extended service life. As Zero Creep Technologyâ„¢ 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.
