Most Helpful Positive Review If you really have to have a red trigger
I got it to add to a black gun with red everything else. I have had many and have many CMC triggers and its the best cartridge style trigger you can buy. the manufacturer has the QC in there court. two part triggers even the best are slave to the lower hole geometry.so it can make even Geiselle trig...

Most Helpful Negative Review Double fires
After running about 40 rounds of factory hornady ammo through a 6.5 grendel AR I had the gun “double fire” on three separate occasions. I know CMC had an issue with this in the last but thought it was fixed

Nice and Crisp

Nice crisp trigger. Can’t beat it for the price. Perfect if you need a red trigger for your build.

Great 3.5 lb trigger

by Mark, from SC, United States Written on November 18, 2023
This trigger looks awesome, but best of all it works great. Extremely easy drop in style, and going from a 6-9lb stock trigger, it's a dream to pull. The flat w hook bottom for finger stop is a nice touch. Colored red, it pops and looks amazing. I am truly happy I went with this product, and if someone else does, they won't be disappointed. On the way is my Cryptic low mass Mystic Gold BCG, and cannot wait for the combo to be together along with the Aero Precision Breach charging handle. All Optics Planet purchases, all amazing products.

Great deal

by smitty, Verified Owner from TX, United States Written on January 27, 2023
Trigger pull is great as well as design. Functions just as I like and as it should. Only 2nd drop in, but I prefer this one over my other. Not much else to say, but as far as the higher priced ones this trigger is right there with them.

Perfect break, imperfect fit

by Monkey357, from WY, United States Written on May 25, 2022
The break on this trigger is divine & installation was wonderfully easy. I put this in a 30 year old Colt A3 and—like some other reviews note—there is some side to side looseness (although the pins hold the trigger securely).
Pros:
  • Break, ease of installation
Cons:
  • Fit
Would recommend: Yes

Very nice trigger

by Rick 259, from CO, United States Written on April 22, 2022
I installed the 2.5lb version in my ar several years ago and I really like it. This one replaced the trigger in my S&W 15-22 and it is just as nice. I very much prefer the flat face over the curved face.
Pros:
  • Extremely smooth operation, quite, well built
  • Very smooth operation- easy to install-various options available
Cons:
  • None
Best Used for:
  • At the range-plinking
Would recommend: Yes

This is one of my favorite triggers

by Jimbo T-rex, Verified Owner from PA, United States Written on March 23, 2022
It was simple to install. It comes with The trigger pins .It’s fired every single time you pull the trigger it’s hard never had a misfire. I don’t believe there’s any creep in it and I think it’s Chris touch the trigger and watch the target.The blue trigger tons of compliments at the range…

Trigger wobble

by alabama-designer, Verified Owner from AL, United States Written on March 3, 2022
The trigger is crisp, easy to install, and functions correctly. The only issue is that there is side-to-side wobble in the trigger. NOT in the whole drop-in unit. That's tight. It's just the actual trigger that has a mm or two of movement.
Pros:
  • Ease of Install
  • Finish
  • Function
  • color
Cons:
  • side-to-side wobble in the trigger
Would recommend: Yes

  • None
