Timney has a large selection of triggers, so you can find the perfect one for your build. If you are building a new AR-10 or just improving the Mil-Spec trigger, the Timney single stage competition trigger is a great option. This AR-10 trigger is very similar to the AR-15, however it has a heavier hammer spring to ensure ignition on harder .308 and 7.62 primers. It is a 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 four-pound trigger pull. The entire line of competition triggers has almost zero overtravel and take-up, resulting in a consistently crisp trigger break. If you are using a .308 for competition, the extremely short reset will help you to pull the trigger faster after recovering from recoil while also making those long-range shots much easier to hit. It features a curved trigger shoe which is highly dependent on shooter preference, however, sometimes it is better to have a more traditional feel. This drop-in fire control group is a great option for those looking to improve their speed and accuracy on the competition line.

  • Stronger hammer spring for reliable ignition
  • Made in the USA.

The Timney AR-10 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.

Timney Trigger


Prices are very competitive and a lot lower then other sites but shipping prices could be a lot better. Other then that I highly recommend this site for gun enthusiast, military, hunters and law enforcement. Aloha, John.



This is the third one of these I have installed, two on AR15s and this last one on an AR308. I have shot the other brands and none is as good as Timney. No creep, no stack, breaks like a glass rod, no overtravel. This is the best.The cost is in your patience in getting the set screws in past the hammer spring so that the trigger and pins are stable. It takes about six or eight tries and doesn't get any easier the third time. A dental pick helps to hold the spring leg to the side so the set screw can be started.
