The Radian Vertex-FB Trigger was designed with functional ergonomics at the center of the design philosophy. The trigger bow is positioned forward of the traditional bow location enhancing the shooter’s ability to make a straight-back trigger break and reducing potential for left and down or right and down trigger pull. – The single stage Vertex-FB Trigger features a crisp 3.5-4 pound break and short reset. The Vertex-FB Trigger’s bow is constructed from 1144 carbon steel and the hammer from precision machined S7 shock resistant tool steel. The hammer is then wire-EDM finished in the interface areas. The components are captured in a lightweight aluminum housing. The Vertex-FB Trigger is compatible with the AR15 platform with a design that prevents pin walkout even when using standard hammer and trigger pins.
