Radian Weapons R0927 Vertex CBX Black Single-Stage Fits AR-15

The Radian Weapons Vertex CBX is a single-stage AR-15 trigger built around a straightforward philosophy: help shooters break cleaner shots with less flinch. Unlike conventional triggers that sit back in the receiver, the Vertex CBX's bow moves forward, putting your finger pad in a more natural position for a straight-back press. That geometry matters when you're trying to hold a tight group—it reduces the arc and torque that can pull your shot left or right, a real advantage whether you're dialing in at the range or executing in the field.

The trigger itself has a curved bow machined from 1144 carbon steel, paired with a hammer forged from precision-cut S7 tool steel—the same shock-resistant alloy used in impact tools. Everything breaks at 3.5 to 4 pounds and resets short, so you can execute follow-ups without losing sight picture or wasting motion. The housing is aluminum, keeping weight down without sacrificing durability. Internal components are Wire-EDM finished for a smooth, consistent action.

This is a no-frills trigger: single-stage, straightforward, and proven in AR-15s from entry-level to high-round-count builds. If you shoot frequently enough to know what trigger ergonomics matter to your accuracy, the Vertex CBX delivers function without pretense.
