Timney 670 AR-10 Competition Trigger 4lb Curved

Timney 670 AR-10 Competition Trigger

The Timney 670 is a precision-engineered drop-in trigger module designed specifically for AR-10 rifles. Each trigger is individually hand-tested and calibrated at the factory to ensure consistent performance and reliability.

Key Features

• Drop-in Installation: Self-contained unit requires no gunsmithing, fitting, or adjustment. Simply install using your rifle's original hammer and trigger pins.
• 4-Pound Pull Weight: Factory-set to deliver a smooth, crisp single-stage trigger pull that feels more like a traditional bolt-action rifle than a combat trigger.
• Precision Construction: Hammer is wire-EDM machined from S7 tool steel for superior hardness and impact resistance. Other components are EDM cut from A2 tool steel and heat-treated to Rc 56-60 for extended service life.
• Durable Housing: Lightweight 6061-T6 aluminum alloy housing is anodized for superior durability and corrosion resistance.
• Superior Lubricity: Teflon Nickel coating on the hammer delivers an exceptionally smooth trigger pull with minimal friction.
• Captive Design: All components are contained within the housing. Proprietary pin design eliminates pin rotation and walkout.
• Small Pin Compatible: Fits AR-10 rifles with small-pin configurations.
• Curved Trigger: Standard curved trigger shoe for traditional shooting ergonomics.

Installation Note

If your AR-10 features a polymer lower receiver, we recommend placing a small thin piece of aluminum underneath the trigger module to protect the polymer from stress.

The Timney 670 represents the pinnacle of aftermarket AR-10 trigger technology—precision engineering that transforms your rifle's performance.
