Radian Vertex Trigger - AR-15 Single-Stage - Curved

The Radian Vertex Curved is a single-stage drop-in trigger for AR-15 and M4 rifles, fitting lower receivers with standard Mil-Spec trigger pins.

The Vertex single-stage with a classic curve — traditional feel, Radian-grade execution.

The Radian Vertex Curved (ACC-0016) delivers the same 3.5–4 lb (1.6–1.8 kg) single-stage break as its flat-bow sibling through a traditional curved trigger shoe — the profile shooters raised on classic rifles find most natural, cradling the finger pad and giving tactile certainty of position without looking for an edge. Take-up is minimal, the break is clean, and the reset is short and distinctly felt.

Radian Weapons' machining discipline shows in a pull that feels identical on every press and stays that way through hard use. A sensible weight and single-stage simplicity make it a superbly versatile upgrade.

Why shooters choose the Vertex Curved

• 3.5–4 lb (1.6–1.8 kg) single-stage break — precision-capable, sensible for general use
• Traditional curved shoe — the classic feel, perfectly executed
• Minimal take-up, positive reset — control at speed
• Radian machining standards — consistency that lasts

What the Vertex Curved fits

Drops into AR-15/M4-pattern lower receivers using standard Mil-Spec trigger pins, so no additional hardware is needed beyond your existing pins. Receivers with oversized pin holes need a different trigger, so check yours before ordering — if you cannot confirm the pin size from the paperwork, measure the holes or ask us. Fitting is an armourer-level job and a full function and safety check must be completed before live firing.
