Radian Vertex CBX Trigger

The Radian Vertex CBX is the curved bow variant of Radian's next-generation single-stage AR-15 trigger, built around TriggerTech's Zero Creep Technology. The CBX replaces conventional sear engagement with a roller-based Frictionless Release Technology (TKR) system that eliminates sliding friction between the trigger and sear. The result is a true zero-creep break with no perceptible movement before the sear releases, extremely short overtravel, and a short tactile reset.

Internal components are hardened 440C stainless steel, chosen for corrosion resistance that does not depend on surface coatings, polishing, or lubrication. FLTWR (Flat Wire) spring technology uses a specially wound flat spring that delivers more consistent force over the trigger's lifespan compared to traditional round wire springs. The combination of roller sear, stainless internals, and flat wire springs produces a break that stays consistent across thousands of rounds without degradation.

The curved bow is positioned forward of the traditional trigger location, promoting a straight-back press that reduces lateral pull tendencies. The distinct angular position guides the finger into repeatable placement, which translates to tighter shot groups and faster splits under a timer. The CBX uses standard mil-spec 0.154" hammer and trigger pins with a built-in anti-walkout design that eliminates the need for KNS pins or anti-rotation hardware. Installation is drop-in with the self-contained cassette housing.
