Timney Competition 4LB Single Stage AR10 Trigger

The Timney Single Stage 4LB AR10 Trigger is an essential upgrade for improving accuracy and speed. A smooth and crisp 4LB trigger pull and short reset is a significant enhancement in comparison to a standard 6-7LB mil-spec single stage trigger. A short and consistent zero creep trigger travel makes fast and on target shots effortless.


Using high-quality materials such as A2 and S7 tool steel in an aluminum housing makes this unit easy to install and ensures the lifetime of the trigger through many rounds and harsh environments. Compatible with all mil-spec AR-10 and .308 Caliber AR platforms and uses your rifles original hammer and trigger pins. This durable upgraded Timney Trigger is the next step to customizing your AR10.
