Product Overview

The Radian Vertex CBX is a curved-bow single-stage drop-in trigger for AR-15 rifles, fitting any Mil-Spec lower with standard .154 in trigger pins.

Radian's current-generation Vertex, curved-bow — a precision-machined single-stage drop-in with a crisp, consistent break.

The Radian Vertex CBX is the curved-bow (CBX) version of Radian Weapons' current Vertex single-stage trigger. Fully self-contained as a drop-in cassette, it delivers a clean take-up, a crisp wall and a consistent break shot to shot, with a fast, positive reset. The curved bow suits shooters who prefer the traditional trigger-shoe profile.

Why shooters choose the Vertex CBX

Precision single-stage break — crisp and consistent
Self-contained drop-in cassette — fast, clean install
Curved bow — traditional trigger-shoe feel
Fast positive reset — control at speed

What the Vertex CBX fits

Drops into any Mil-Spec AR-15 lower receiver with standard .154 in trigger pins. Because the unit is a self-contained cassette there are no separate springs to fit, and pins are supplied. Large-pin receivers will not take it, so confirm your pin size before ordering. Complete a full function and safety check before live fire. If you would rather have a flat shoe, the Vertex FBX is the same trigger with a flat bow.

Product Questions

Will the Vertex CBX fit my lower?

It drops into any Mil-Spec AR-15 lower receiver with standard .154 in trigger pins. Large-pin receivers will not take it, so confirm your pin size before ordering — if you cannot tell from the paperwork, measure the pin holes or ask us with the make and model to hand. The unit arrives as a self-contained cassette with pins supplied.

What does a drop-in cassette trigger actually change?

Everything that makes the trigger work sits in one self-contained housing rather than going into the receiver as loose parts. That means the geometry is set before it reaches you instead of depending on how your particular lower is machined, which is what gives the crisp wall and consistent break from one rifle to the next. It also means there are no separate springs to fit.

Should I take the curved bow or the flat?

Mechanically the CBX and the flat-bow FBX are the same trigger; the difference is the shape of the shoe your finger sits on. The curved bow feels familiar if you have come off a standard Mil-Spec trigger and naturally centres the finger, while a flat shoe keeps the leverage identical wherever you press. Compare the alternatives in AR-15 triggers, or read our AR-15 trigger guide if you are still choosing between single- and two-stage.

Is fitting straightforward?

The install is quick because the cassette goes in as one piece and the pins are supplied, but this is armourer-level work on the fire-control group rather than a bolt-on accessory. If you have not done it before, have a gunsmith fit it. Either way, complete a full function and safety check before live fire.

How will it arrive?

Triggers are sent from the United Kingdom with £5 tracked UK delivery in 7–10 business days, and you’ll get tracking by email when it ships. If a part turns out to be the wrong fit, see our returns policy or contact us and we’ll help sort it.
