Vertex Trigger for AR-15 – Radian®

The Vertex trigger by :contentReference[oaicite:0]{index=0} is designed for AR-15 platform rifles and focuses on consistent trigger control, predictable break, and long-term durability. The forward-shifted trigger geometry allows the firing finger to pull straight to the rear, reducing lateral input and improving repeatability. The construction combines hardened steel components with a lightweight aluminum housing while addressing common issues such as trigger pin movement.

Trigger Geometry and Ergonomics

The Vertex trigger features a forward-positioned trigger face that promotes a direct rearward press. This geometry reduces side loading and minimizes finger slip during rapid or repeated firing. The shape is intentionally functional, supporting consistent finger placement and predictable trigger control rather than decorative styling.

Trigger Feel and Reset

The trigger delivers a clean, clearly defined break followed by a fast and positive reset. Reduced unnecessary movement helps shooters maintain cadence during rapid strings of fire and improves consistency between shots. The response remains intuitive and controllable even during dynamic use.

Materials and Manufacturing

Key components are manufactured from 1144 carbon steel, while the hammer is machined from S7 tool steel to withstand repeated impact and long-term use. Critical engagement surfaces are finished using wire EDM to ensure precise geometry and consistent contact. All components are housed in a lightweight aluminum cassette that reduces overall weight without compromising structural strength.

Installation and Compatibility

The Vertex trigger is designed for standard AR-15 trigger pin interfaces. Its construction helps prevent trigger pin walkout during operation, eliminating the need for additional anti-walk hardware. Installation is straightforward and compatible with common AR-15 lower receivers without special tools or adapters.

Intended Use

This trigger is intended for shooters who want improved trigger consistency and control across a wide range of applications, including sport shooting, training, tactical use, hunting, and recreational shooting. It offers a practical performance upgrade without unnecessary complexity.
