Product Description The Radian Weapons Vertex Trigger is engineered around functional ergonomics to help shooters achieve a cleaner, more consistent trigger press. Its trigger bow is positioned forward of the traditional bow location to promote a straight-back break and reduce lateral input during the pull. This single-stage trigger delivers a crisp 3.5-4.0 lb break with a short reset for fast follow-up shots. Built with a durable 1144 carbon steel trigger bow and a precision-machined S7 shock-resistant tool steel hammer with wire-EDM-finished interface areas, the components are captured in a lightweight aluminum housing. Designed for AR15 compatibility, the Vertex incorporates a design intended to prevent trigger/hammer pin walkout even when using standard pins.
