JARD AR Two-Stage Trigger System Heavy 4.5 lb Black. Two Stage Operation provides a buffer of take-up or pretravel that leads up to a tangible "wall" before the trigger breaks. This adds an extra element of not only safety but trigger control and shot anticipation as well. Built to perform this trigger kit serves as the perfect duty or defense AR trigger. It blends JARD's signature smooth pull and crisp clean break with an effortless 2 - 4.25 lbs. pull weight making it much easier to precisely place longer shots. If using .17 WSM or another cartridge with hard to ignite primers we recommend the Heavy Spring option. Two Stage Operation Regular Spring pull weight ranges from 2 - 4.25 lbs.
