TriggerTech AR15 Duty Trigger - Available with a Curved or Flat Trigger Profile. The TriggerTech AR-15 Single-Stage 3.5lb Duty Trigger is made from high-grade materials, including EZAC diecast aluminum housing and 440C stainless steel internals. It features patented Zero Creep Technology that eliminates the need for sliding friction between the trigger and the sear. This results in a smooth and crisp trigger pull that is consistent and reliable. The trigger also features a short reset and reduced overtravel, which allows for faster follow-up shots and improved accuracy. The 3.5lb pull weight is perfect for those who want a lighter trigger pull without sacrificing safety.
