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.
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.

£5 tracked UK delivery on every order via Royal Mail Tracked 24. Our products are ordered in from the manufacturer rather than held in UK stock, so please allow 7 to 10 business days (Monday to Friday, excluding bank holidays) from the date of your order for it to reach you. Tracking details are emailed on dispatch. UK delivery only.
You have 30 days from receiving your order to cancel it for any reason, then 14 days to send it back unused and in its original packaging. Faulty, damaged or incorrect items are replaced or refunded and we cover reasonable return postage. Refunds go back to your original payment method within 14 days of receiving the return.
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.
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.
Mechanically the CBX and the <a href="/products/radian-vertex-fbx-single-stage-trigger-ar-15">flat-bow FBX</a> 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 <a href="/collections/ar-15-triggers">AR-15 triggers</a>, or read our <a href="/blogs/buying-guides/ar-15-trigger-guide">AR-15 trigger guide</a> if you are still choosing between single- and two-stage.
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.
