Reviews & Ratings for Triggertech AR-15 Diamond Trigger — 47 reviews — Page 1

This was my first time replacing a trigger on my Colt AR15 and I was very pleased with how easy it was. I watched some videos on YouTube and probably the most difficult stage was removing the safety. Be careful to watch for the small pin that holds it in once the pistol grip is removed. Trigger tech directions were easy to follow and the install was a breeze. I’ve seen some posts about needing antiwalk pins but that is unnecessary once the trigger is firmly in place using the supplied hex wrench. I followed all the safety checks in the manual and headed to the range. With one round loaded I checked the safety as instructed then fired a round. Wow! So crisp and fast! I left it at factory settings, I believe 1.5 as opposed to milspec of 5+. It took a few rounds to adjust but then it was so natural. Much easier to get tight groups as you’re not fighting the trigger pull. Fantastic trigger, super easy install!

I was looking to upgrade my trigger. The installment of the trigger was easy and took less than a minute. I highly recommend

This isn’t just a good trigger — it’s the best trigger I’ve ever felt on an AR platform. Installation was ridiculously simple — drop it in, tighten the set screws, done. No guesswork, no fitment issues, just instant precision.

But the real magic is in the pull. The click-click of the two-stage action is almost hypnotic — the wall is glassy, the break is lightning, and the reset is so short and tactile it feels like the trigger knows what you want before you do. It’s crisp, clean, and entirely predictable. There’s zero creep, no overtravel, and every shot feels deliberate.

Whether you're shooting suppressed .300 BLK or ringing steel fast, this trigger gives you total control without ever feeling heavy or vague. It’s like a 1911 trigger and a surgical scalpel had a baby and dressed it in DLC.

I have bought 6 of these so far because I never found anything as nice as the Trigger Tech Diamond. I tried them all and none measured up to my expectations.

Perfect addition to my furniture and exceeds it's reputation easy install.

Can’t find a better trigger.
If you want a little bit of creep so you know when the trigger is going to go boom, there is nothing better,, maybe just as good but better not a chance.

Either you like a single or two stage this trigger tech 2 stage is not going to make you pull off target especially at 1.5-2 lbs of force that is required to fire your weapon.
I highly recommend it, but there are a lot of good ones out there that I have tried that dollar for dollar are very good as well. But this one sits at the very top 2-3 triggers.

I have always loved the feel of Triggertech triggers and this one is one of the best. You can’t go wrong and you get what you pay for.

Best upgrade I've done for my Rock river, high quality crisp,reliable.

Vertical, well designed and shoots amazing. I use it in my precision AR hunting builds and works great.

I have not shot this at the range yet, but from the dry firing it feels great. This drop-in trigger is very easy to install if you have all of your AR lower parts on hand already. Namely the trigger pins. I made the mistake of being impatient and tried to install it with only 1 pin, resulting in a piece snapping off. Triggertech just said send it back and we will offer you a replacement, even though I asked for a repair under negligence. If you have the money to spend on a triggertech I can recommend them just based on customer service.
