Radian Vertex Flat Bow Trigger — Single-Stage 3.5-4 lb

The Radian Vertex Flat Bow (Vertex-FB) Trigger is a single-stage trigger designed for AR-15 platform use. The forward-positioned flat bow encourages a straight-back trigger break to reduce common lateral or downward pull tendencies. It delivers a crisp trigger break in the 3.5-4 pound range and a short reset for quick follow-up shots. Components combine hardened steels and a lightweight aluminum housing for a balance of durability and weight savings.
