Description
The Radian Weapons Vertex CBX is a drop-in single-stage trigger built for AR-15 shooters who want a cleaner, more consistent break than a standard mil-spec unit without chasing an ultra-light pull weight that introduces uncertainty in field conditions. The curved bow of the CBX gives your trigger finger a natural reference point at the same position on every shot, which matters more than it sounds when you’re running drills or hunting under time pressure.
Single-stage triggers remove the take-up travel present in two-stage designs, so the wall and the break arrive at the same point in the pull stroke. That characteristic suits shooters who prefer a direct, predictable feel and don’t need the deliberate staged reset that competition precision shooters sometimes favor. The Vertex is engineered to install as a complete unit — hammer, trigger, and associated components arrive as an assembly — which keeps timing relationships consistent and removes the variable of mixing parts from different sources.
Radian pairs a black trigger bow with a silver hammer in this configuration, which makes the installed assembly visually easy to inspect inside the lower receiver. The Vertex line is designed to fit standard AR-15 lower receivers without modification to the receiver itself. If you’re building or upgrading a rifle that sees regular use rather than sitting in a safe, this is a thoughtful upgrade that addresses one of the few areas where factory AR triggers genuinely leave room for improvement.
