The TriggerTech Adaptable Primary Trigger (TriggerTech part number AR0TBS25NNF) is a flat-shoe, drop-in AR-15 trigger built to work well in every role a rifle might be asked to fill, from home defense to range use. It uses TriggerTech’s Frictionless Release Technology to deliver a short, two-stage action that feels closer to a tuned 1911 trigger than a typical mil-spec AR trigger. Pull weight is adjusted with CLKR Technology through a set screw that stays accessible with the trigger installed, moving from 2.5 to 5.0 pounds in 2-ounce increments so a shooter can dial in exactly the feel they want without removing the trigger group. Internals are hardened 440C stainless steel, chosen for corrosion resistance and a long service life under repeated cycling.
