Timney AR-15 Competition Trigger | Flat | 4lb

Timney AR-15 Competition Trigger | Flat | 4 lb

The Timney AR-15 Competition Trigger is a self-contained, cassette-style trigger upgrade for compatible small-pin AR-15 and M4-pattern rifles. This flat/straight 4 lb version gives AR builders a clean single-stage trigger pull with a crisp, creep-free break and a more refined feel than many standard factory trigger groups.

The flat trigger shoe provides a straight trigger face for consistent finger placement and a direct rearward press. For shooters who prefer a single-stage trigger with immediate engagement rather than a two-stage take-up, this configuration offers a predictable 4 lb break that works well for range rifles, precision-focused AR builds, hunting setups, varmint rifles, and competition-oriented rifles.

Timney designs the AR-15 Competition Trigger as a 100% drop-in module with no gunsmithing, fitting, or user adjustment required. All components are captive inside the lightweight aluminum alloy housing, helping simplify installation while keeping the trigger assembly contained and aligned inside the lower receiver.

The hammer is wire-EDM machined from S7 tool steel for wear resistance and impact strength. Additional internal components are EDM cut from A2 tool steel and heat-treated to Rc 56-60 for long service life. Precision-ground engagement surfaces help support the smooth pull, clean hammer release, and repeatable trigger feel Timney’s Competition Trigger series is known for.

The trigger installs using the rifle’s original hammer and trigger pins, while Timney’s proprietary design helps eliminate pin walkout without requiring anti-walk pins. Each trigger is hand-assembled, tested, and calibrated before leaving the factory and is backed by Timney’s lifetime warranty.
