One of the easiest upgrades you can make for your AR-15 rifle is the trigger. If you are building a new rifle or just improving the Mil-Spec trigger, the Timney single stage competition trigger is a great option. This AR-15 trigger group is completely self-contained drop in unit that makes upgrading as simple as driving out the pins on your old trigger and replacing it with this fire control group. This Timney trigger gets rid of the heavy, gritty, and inconsistency of standard triggers and does so with a three-pound trigger pull. The entire line of AR-15 competition triggers have almost zero overtravel and take-up, resulting in a consistently crisp trigger break. The short rest allows you to pull the trigger extremely fast for those close quarters encounters during a 3-gun competition but is still capable for long range shots. It features a straight trigger shoe which is highly dependent on shooter preference, however, the flat design is known for being comfortable and consistent. This drop-in fire control group is a great option for those looking to improve their speed on the competition line.

  • Single-stage 3 lb trigger pull
  • Fits Mil-Spec AR-15 lower receivers with .154” pins
  • Drop-in design
  • Wire-EDM machined hammer from S7 tool steel
  • Lightweight aluminum housing
  • Heat treated to Rc 56-60 hardness
  • Straight trigger shoe
  • Lightened hammer
  • Made in the USA.

The Timney AR-15 competition trigger is wire EDM machined from heat treated S7 tool steel with an aluminum housing, so you don’t have to worry about it breaking after years of heavy use. The single-piece drop-in design is easy to install and is more reliable than standard fire control groups because it keeps dirt and debris from getting inside the mechanism. Each and every trigger is individually tested and calibrated by hand before leaving the factory floor.

This trigger group is non-adjustable to reduce the amount of parts that are potential failure points, so you can rely on it in any stressful situation. All engagement surfaces are precision ground to produce a smooth consistent pull that breaks in the same spot every time leading to greater accuracy.

Timney Triggers was founded in 1946 with the mission to bring consumers high quality, precision AR-15 and AR-10 components. They have since built a reputation that resembles this sentiment by providing triggers that are optimized for competition use by competition shooters. If you have an AR, it needs a Timney trigger.

One of the BEST !!!


I Like this trigger Better than the Geisselle Super Dynamic 3 Gun trigger as it is More Crisp and has a shorter reset and is Easier to Bumpfire if you wish, Overall a Better trigger than a Geisselle !!! Buy one you Wont be Disappointed :)

The Best AR-15 trigger out there for the money!!!


The Best Ar-15 trigger out there for the money period, it has a Very Short reset and Very little take up Even less than the Bigger more expensive triggers and it IS Very controllable so you wont bumpfire it unless you want to!!! This is my Favorite trigger so Far !!! :)

Under the radar.


A Very Good Trigger that is little known of but that Should change! It has a very short reset and very crisp break that is Very tactile it feels expensive and of high quality.



Installed my new 3 lb Comp Timney and I consider it a major improvement over the factory trigger in my Radical Arms AR. Crisp clean and little to no pull or reset slack. Wish the rain would stop so I could go shoot!!
