TriggerTech AR Diamond single stage trigger

  I am someone that is always looking for the newest and best AR trigger. I have found some that are pretty fantastic. Which leads me to the Triggertech AR Diamond Single stage trigger. The Diamond is Triggertech’s top of the line model and it shows. They were gracious enough to send me one for review, and I am glad they did.

  For this particular review, I opted for the straight trigger shoe. Triggertech also has a curved option in the Diamond line, if that is your pleasure. I am known to like a curved trigger, but for a hi-performance trigger, I can get behind the straight options. The shoe is definitely straight and flat, but also has a tiny hook/knob at the foot. There are no sharp edges anywhere on the trigger,  even if it looks like there would be. The trigger felt great to me, which surprised me since it has no texture on it and is super smooth. Part of that feel is in the trigger operation, but more on that later. Triggertech also puts a “TT” at the very top of the trigger, where it pivots. A nice touch to say whose trigger it is.

  Let’s get into what makes the Triggertech Diamond single stage work so well. The most notable aspect to Triggertech triggers is their use of a roller between the sear and the trigger. They call this Frictionless release technology (FRT). This roller allows the trigger to not have any friction in the actual trigger pull. Most every other trigger on the market uses the friction between the sear and the trigger. You can definitely feel the difference because of the FRT, especially if you compare it to a standard friction trigger. They also use their TRK system to give you the shortest trigger pull possible. If you are curious about their other tech, check out their How-It-Works page.  

  Since the Diamond trigger is at the top of Triggertech’s lineup, it is adjustable. Triggertech states an adjustable pull from 1.5 lbs to 4.0 lbs. I can attest to these values, as I adjusted it all the way down and back up. To adjust the trigger pull weight, there is a set screw at the rear of the trigger housing. Turn clockwise to increase pull weight, and counterclockwise to decrease pull weight. This set screw also uses Triggertech’s Clicker technology. Essentially the set screw clicks every 2 oz of pull weight. The Clicker adjustment makes adjusting the pull weight super easy. I have mine set at 2 lbs and love it. The Diamond came set at 2.5 lbs on my trigger pull scale. It is definitely one of the easier triggers to adjust, due to that single adjustment screw.

  For those wondering, the Triggertech Diamond is a drop in style trigger. This cartridge style makes installation easy. The cartridge is made from 7075 aluminum. Does it need to be this higher grade of aluminum? Probably not, but it does show quality. If you are worried about it wearing out, don’t. Even if it did, it’s covered by the lifetime warranty. One thing I wish that Triggertech included were anti-walk pins. Yes I can get them inexpensively, but in a top tier trigger, I think they should be included. I have criticized other companies for the same thing, even if it is kind of nitpicking.

  Now for the really good stuff. The Triggertech Diamond has essentially zero take up or creep. Yes, I can’t perceive any, or measure it with the tools I have. There is also zero perceived over travel. You simply put your finger on the trigger and apply pressure. Then the trigger breaks with one of the cleanest breaks I have felt on an AR trigger. When I measured the total movement of the trigger, it measured at 0.050”. This was at the very bottom of the trigger shoe, so it is less as you move your finger up the trigger shoe. The trigger pull on the Triggertech Diamond is fantastic. Now comes my only complaint, and it’s minor. I would like the reset to be stronger. Triggertech calls it “tactile mid force”, which I think is a fair explanation. The reset works fine, even when shooting really fast, I just want a tactile high force reset. This trigger can be shot super fast if that’s what you want. If you like single stage triggers in a precision gun, it would do a fantastic job there too.

  The Triggertech Diamond has impressed everyone that I let use it, even me. The Diamond is just that good. I did run it in a local match where it performed well. There were some rapid fire targets, and some small precise targets. The Diamond made it easy to do both and transition between them. When the sight was on target, I just touched the trigger and made decent hits. I attribute this to the consistent pull weight and lack of any trigger take up. The Triggertech Diamond is now in my top 2 triggers for an AR. The Diamond is a better all around trigger than my other top pick, which is more a speed trigger. The Diamond single stage can do everything an AR trigger should do, and it does it extremely well.

  If you are looking for a great AR trigger, do not skip over looking into Triggertech. The Diamond AR single stage trigger does everything one could ask for. It works for precision shooting, as well as ultra fast shooting. I definitely place it in the best of the best category.

What others are saying?:

5 out of 5 stars from Tuomas K. at TriggerTech 

I have been solely using Triggertech triggers on all my platforms since the IPSC World Shoot Rifle 2019. I have tried a lot of other triggers throughout the years and can happily say that I found the best in Triggertech Triggers. I run them on my AR-platforms, PCC:s and my PRS rigs. The Diamond triggers are beautiful and I love the action and the clean break in them.

Even though I love my red Diamonds for the AR-platforms, the new Single Stage Diamond Trigger will be my go-to trigger for the future. Got the opportunity to test this trigger out and I basically love It!

Superfast, short distinct reset and breaks like glass, every time!
