AR-15 / AR-10 – Single-Stage Trigger – 3.5–4 lb Break – Vertex
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Radian Weapons Vertex is a premium single-stage drop-in trigger built for AR-pattern rifles. It delivers a crisp 3.5–4 lb break with a short reset and comes in two trigger shoe styles in this batch: Curved and Flat. Available options are organized below under Variants.
This is a function-first trigger, not just jewelry for the lower. The big selling points are the clean break, short reset, forward-positioned bow geometry, and drop-in cassette format. :contentReference[oaicite:0]{index=0}
Fitment
- Fits AR-15 platform rifles
- Retailer listings reviewed also identify compatibility with AR-10 rifles
- Drop-in cassette-style trigger for AR-pattern lowers
Does NOT fit
Do not assume fitment for non-AR platforms. Verify your receiver uses standard AR trigger geometry before purchase.
What it does
Replaces the factory trigger with a single-stage unit that offers a cleaner break, shorter reset, and better control for shooters who want more precision and consistency than a typical mil-spec trigger delivers. :contentReference[oaicite:1]{index=1}
Why it’s worth it
The Vertex sits in premium-trigger territory. It is built for people who actually care what the trigger feels like and want a cleaner press without drifting into vague “trust me bro” marketing. The curved shoe is the traditional play; the flat shoe is for shooters who prefer a straighter press and a different finger index. :contentReference[oaicite:2]{index=2}
