Timney Impact 3-4LB Single Stage Impact AR Trigger

Performance meets price with the Timney Impact AR15 Trigger. This inexpensive drop-in trigger is an easy to install upgrade that instantly improves your shooting experience. Available in either a curved or flat trigger bow, this smooth single stage trigger pull consistently gives a clean break and short reset around 3-4LB of pressure. In comparison, a standard mil-spec trigger pull is 6-7LB with gritty travel and longer resets, making it harder to shoot accurately and quickly.


Each trigger is tested by Timney technicians before the trigger is shipped to ensure long lasting performance and quality control standards. Using solid materials such as A2 and S7 tool steel for the hammer, trigger, and internal components inside of an aluminum alloy house makes this trigger reliable, simple, and effortless to install. Make the next step towards the a performance AR15 at a great price with the Timney Impact Trigger.

So good that I bought another for my AR pistol!

Crispy, nice short reset, and short low 3 pound pull. Amazing!!!

Great review! I'm glad you're happy with the trigger.
