Buy on Ammo Depot

The Radian Vertex FBX Flat Trigger is a drop-in AR-15 trigger built around a forward-positioned flat bow that encourages a straight-back pull and a consistent break. Its 3.5–4 lb break weight and short reset support repeatable trigger control for precision and tactical shooting.

The bow is made from 1144 carbon steel, paired with a precision-machined S7 shock-resistant tool steel hammer and Wire-EDM finished internals inside a lightweight aluminum housing. The result is a durable, smooth-running fire control group designed for the AR-15 platform.
