Most Helpful Positive Review CMC Trigger 2.5#
Bought this CMC 2.5# to replace my stock M&P 15-22 trigger. My groupings tighten up by 1/2". I didn't find if any take up; you are literally at the wall and the reset is very positive and short. For the price, it's quite hard to beat and hard to find a drop in trigger at around 2.5#. Installation...

Most Helpful Negative Review Disappointing
Installed easily, works dependably, but has some take up (creep)and measures in at 3.0 lbs. For a "2 to 2.5 lb trigger" this is not what I was expecting. There are plenty of 3.5 lb triggers on the market. I was looking for something lighter. Unfortunately this one isn't anywhere near the 2 lb mark.

Great Trigger at a Good Price

This trigger was installed on a 6 ARC build. It immediately improved accuracy and was easy to install.

Pull Weight & Break Is Fine, Reset Is Terrible

by wildcatgoal, from GA, United States Written on May 16, 2026
Pull weight feels the same more or less as my other 2/2.5 lbs. AR triggers from other manufacturers. The break is not exactly what I would call "glass-like" but it's very good. When you're used to a Geissele SSA-E or the higher end Hiperfire triggers, you'll be able to tell this has a more "clunky" feel to the pull. It's not so much creep but it doesn't feel as glassy through the brake... nothing you will actually ever notice unless you're shooting off a bench intentionally shooting slowly. What you will notice is that the reset feels like it's a mile long and 25% of the time, it hangs up halfway through that reset, especially when you slowly reset your trigger finger. The reset is frankly terrible and disqualifies this as a viable 3-gun/2-gun/race gun trigger as the packaging implies. The rest also doesn't seem to have any assist. You don't need much assist unless you're intentionally trying to get as close to a super safety as possible without having one, but you literally feel like you have to almost coax the trigger back forward... it doesn't follow your finger at the same pace (and, like I said, will want to hang up sometimes). I had to put a little dab of Breakthrough on the contact points on mine to get it to smooth out but it still isn't what I anticipated for something dubbed a "Competition Trigger". I do like the trigger shoe... I didn't think I would like that little kickout on the bottom but it's actually quite comfortable and acts as a great guide. The ...

CMC Triggers Drop in Single Stage 2.5

by Brown, Verified Owner from UT, United States Written on March 18, 2026
Decent trigger at a decent price. Put it in my 6MM ARC precision build as an upgrade over a cheaper two stage. It’s hard to compare it to my bolt gun precision triggers but It’s definitely the best AR 15 trigger I have.

Great Trigger

by Joe, Verified Owner from CO, United States Written on March 12, 2026
I prefer a single stage trigger and this one just feels right to me. I have to same trigger in each AR platform. Consistency matters. Easy installation and all tools are included. I highly recommend a small drop of blue Loctite on each screw for peace of mind.
Pros:
  • Everything from my perspective. Design, price, quality, application.
Cons:
  • None
Best Used for:
  • general

The only aftermarket trigger i’ll use in my AR’s

by EJB, Verified Owner from UT, United States Written on March 2, 2026
I absolutely love this trigger!
I have one in all of my rifles and they are the best I’ve ever used. The 2.5lb trigger is smooth and breaks clean.
I cannot recommend this trigger enough!

I promise you will not regret buying a CMC trigger.

Perfect Drop in upgrade

Got this one to replace a factory setup and the difference is like night & day. Trigger pins are nice too as they are Torix and not just your common Allen head screws.
Pros:
  • Easy drop in install
  • Smoth trigger pull
Cons:
  • None
Best Used for:
  • ARs 10 & 15 and others
Would recommend: Yes

Excellent Trigger

by Bilbo, Verified Owner from GA, United States Written on January 24, 2025
This trigger is truly nice. Installation was easy. Zero take up. Glass like break. Extremely short reset. Two and a half pound pull is awesome. Well worth the money. Happy mag dumping.

Snappy Single stage

by Austin B, from MO, United States Written on January 24, 2025
Building a duty style rifle i wanted a super crisp trigger with no take up at all and I have found it. This trigger has a super clean break, doesn't move until the break and a super short reset. The flat face is nice but could use some serrated faces.
Pros:
  • Installation
  • looks great!
  • Pull weight & crispness
Cons:
  • Super Smooth operating surface
Best Used for:
  • Shots in rapid succession
  • Drills/training
Would recommend: Yes
