Description

The Radian Vertex is the same trigger Radian runs in their own Model 1 rifle, so you know it earned its spot rather than getting slapped together as an afterthought. It delivers a clean single-stage break in the 3.5 to 4 pound range with almost no takeup and a short, positive reset that lets you get right back on target. If your factory trigger feels mushy or gritty, this is the kind of upgrade you notice on the very first shot.

What Sets the Vertex Bow Apart

The headline feature here is geometry. Radian positioned the trigger bow forward of where a traditional bow sits, which encourages a straight-back press and cuts down on the left-and-down or right-and-down drift that pulls your shots off center. On paper that sounds like marketing, but on the range it translates to more consistent finger placement and tighter groups, especially when you start pushing speed. This is the curved-face version, so if you prefer the familiar feel of a conventional trigger shoe while still getting the improved bow position, this is the one.

Materials That Hold Up Round After Round

Radian didn't cut corners on the guts. The trigger bow is machined from 1144 carbon steel and the hammer from S7 shock-resistant tool steel, with the hammer's interface areas wire-EDM finished for clean, precise engagement. Everything rides in a lightweight aluminum housing, and the self-contained cassette design means there's no fine-tuning or fitting required.

Getting the Vertex Into Your Lower

Installation is about as painless as it gets. It's a true drop-in unit that runs on standard mil-spec 0.154 inch hammer and trigger pins, and the housing is engineered to prevent pin walkout even with those standard pins. Most folks have it seated and running in well under ten minutes with basic tools. Give the instructions a quick read before you start and you'll be set. It fits standard AR-15 lowers and works equally well in a duty carbine, a competition build, or a range gun you just want to shoot better.

Frequently Asked Questions

Is the Radian Vertex Trigger a true drop-in unit?

Yes. The Vertex is a self-contained cassette-style trigger that drops into a standard AR-15 lower with no fitting or fine-tuning. Most people have it installed in well under ten minutes with basic tools. Read through the instructions first, since it uses set screws to lock everything down.

Does the Vertex Trigger come with the pins I need?

It does. The Vertex ships with standard mil-spec 0.154 inch hammer and trigger pins, so you can install it right out of the box. The housing is also designed to prevent pin walkout even with those standard pins.

What's the difference between the curved and flat Vertex triggers?

Both share the same forward-positioned bow, materials, and 3.5 to 4 lb single-stage break. This ACC-0016 is the curved-face version, which keeps the familiar feel of a traditional trigger shoe. The flat model (ACC-0017) offers a flatter face that some prefer for consistent finger placement, so it really comes down to personal preference.

Will the Vertex Trigger fit my AR-15?

The Vertex is built for the standard AR-15 platform and drops into standard mil-spec lowers using standard 0.154 inch pins. If you're building or upgrading a common AR-15 lower, it should slot right in. For anything beyond standard AR-15 fitment, it's worth confirming with Radian directly.
