Vertex FB Straight Trigger for AR-15 – Radian®

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

Forward Geometry and Ergonomics

The Vertex FB features a straight trigger with its contact surface positioned further forward than traditional AR triggers. This geometry encourages a direct rearward press, minimizing side loading and reducing the tendency for the finger to slip during rapid or repeated firing. The shape is functional rather than decorative, supporting consistent finger placement and predictable control.

Trigger Behavior and Reset

The trigger delivers a clean, well-defined break followed by a fast and positive reset. Reduced unnecessary movement helps shooters maintain rhythm during rapid strings of fire and improves consistency between shots. The response remains clear and repeatable, even under dynamic use.

Materials and Manufacturing

Key components are manufactured from 1144 carbon steel, while the hammer is machined from S7 tool steel for increased durability under repeated impact. Critical engagement surfaces are finished using wire EDM to ensure precise geometry and consistent contact. The components are housed in a lightweight aluminum cassette, reducing overall weight without sacrificing structural integrity.

Installation and Platform Compatibility

The Vertex FB 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 suited for shooters looking to improve trigger consistency and control across a wide range of applications, including sport shooting, training, tactical use, and general recreational shooting. It is designed as a practical upgrade that enhances trigger feel without unnecessary complexity.
