Radian Vertex Trigger — Single-Stage AR‑15, 3.5–4 lb

Description

The Radian Vertex Trigger is a single-stage trigger designed for AR-15 platforms with an emphasis on ergonomic trigger geometry and reliable operation. Its trigger bow is positioned forward of a traditional bow to encourage a straight-back trigger break and reduce lateral pull tendencies. The Vertex delivers a crisp 3.5–4 lb break with a short reset and is built from purpose-chosen materials for durability in service use. Components are finished and assembled in a lightweight housing intended to integrate cleanly into standard AR-15 fire-control groups.
