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.

Timney 668-S Competition Solid AR-15 Trigger 4lb
Decided to purchase and try out this trigger system. Install was very fast, and pull and reset excellent. For those wanting an upgrade from their stock triggers I would recommend this single stage crisp pull trigger.
by Jeff Reiss
Easy installation. Excellent instructions. Best trigger assembly there is.
Excellent Service and Trigger
First thanks to PA for the great service - I received my order in 3 days (with the standard shipping). Next the Trigger - I am VERY happy with this. It has an excellent clean break at just under 4lbs. VERY easy installation. I had purchased a POF trigger at my LGS - it was light but had consistent creep right before break (maybe I just got a bad one). But not what I expected from a $200 trigger (returned it). Bought Timney because of the great reviews - they are justified.

Good trigger! Nice doing business with Primary arms. As a gunsmith I never worry about customer service with PA.
Great product delivery was quick
by Chet Botkins
Great service. Fast service.Trigger is the best. Breaks like a glass rod.
by Matthew Durow
I did a lot of research on different triggers before I decided to buy this one. It was my first aftermarket trigger in a firearm, and I couldn't be happier. The pull is crisp, light, and easy to get consistent with. There is almost no creep, and the overall trigger pull is measured to just 2mm. I would highly recommend this to everyone as a match trigger, marksmen trigger, or overall patrol trigger. I'm in love with it.

I replaced my AR-15 stock trigger and this should be something that all should do...
by James Giorgi
I was looking at either a Timney or a CMC and I am very happy with the Timney. Very crisp and the reset is very short. Primary arms has a great price as well.
Awesome trigger, fast shipping!
I'll be getting another as soon as possible. One of the fastest business I've dealt with.

JUST WHAT I WANTED
Well designed trigger!
by Eric Meyers
Ok, first non-stock trigger I chose to purchase, and I am really impressed. Well manufactured, clean break, and perfect fit. Make sure you read the install instructions carefully, it's a little different with the front trigger pin.

On time excellent price
by Josh Smith
Primary Arms always has great prices, a large selection, and super fast shipping !
by Jonathan Brown
Same performance as the skeletonized trigger, just a little less costly.
Single stage, no mush, clean break, short reset. Easy to install.
Very nice trigger
by Randall Melloncamp
The Timney 4 pound trigger is so sweet, no creep and such a clean break when pulled. I would have given 5 stars if not for the difficult install. The trigger slides right in and the set screws that tighten up the hammer and trigger pins are no problem. The two screws that thread in to lock the set screws are a different story. They turned a 10 minute install into a 30 minute test of my patience.
by josh tupper
This is a great trigger breaks cleanly at 4lbs, minimal take-up and almost no over-travel. I will buy a couple more to replace the factory triggers in my other ar's.
PRIMARY ARMS IS AWESOME
This is my first Timney AR trigger. Definitely worth the cost . I have a couple Geiselle sse triggers and for the same cost this is a nicer trigger. Rumor is they hold up better than standard style trigger for 9mm AR's. time will tell.
This trigger is one of the best upgrades you can do for your AR. Primary Arms has the best price around and their customer service is excellent. thanks Jason

Crisp Break, Like Breaking A Glass Rod
by Anthony R.
Timney triggers are extremely high quality triggers and, their customer service is the best you will find anywhere.Primary Arms has the lowest pricing on them too. And their shipping is super fast! Like a high velocity 204 Ruger... 4000fps. :PThanks Primary Arms!!
excellent trigger, quick shipping
by Jason cook
Trigger is easy to install. Im not sure i could reinstall the mil spec trigger without detailed diections and allot of time, but installing this trigger was truly drop in. Requires a allan wrench, and it was included. I decided on the 4lb because i dint want a hair trigger, and i find it requires a deliberate pull, and 4lb feels accurate. Crisp clean break. Highly recommend. Primary Arms had the best price, by far. Shipped quick. Also highly recommend
