Assembling an AR-15 for the most part is pretty simple; however, some aspects of the process can be frustrating such as installing the takedown detent and spring or trying to put the trigger together. CMC Triggers saw a need to improve on the AR15 trigger installation process and introduced their line of completely self-contained trigger groups. Each trigger is encased in 8620 alloy steel to protect the internal components from dirt and debris, carbon buildup, or anything else that might get into the lower receiver and can be installed in seconds. Just drop it in, install the Mil-Spec trigger pins and you are ready to go. They have a huge selection of triggers that are built for specific applications and preferences. This model is designed for target shooting, home defense, and hunting as it has a light trigger pull to improve accuracy without sacrificing reliability or safety. Install this fire control group today and experience a smooth trigger pull like never before.
With roots in aerospace manufacturing, CMC is perhaps best known as the producer of the original drop-in precision trigger for the AR-15/10 platform. CMC Triggers are dedicated to crafting the finest parts and accessories for law enforcement, military, and civilian use.

CMC - The absolute best
by Evan Shepard
Bought my first CMC 3.5LB flat trigger a while back. Since I made the change, I have installed 4 more and now have one on every rifle I own. You just can't beat the feel of this trigger. Excellent buy. Buy with confidence.

Bought the trigger on good word from other shooters, and I was definitely pleased. Great product from CMC, and of course. Always great service from Primary Arms. Only thing I can complain about is the fit I got from the supplied pins. Not to mention that I had on of the heads break from the screws. All in all. A great trigger.
Excellent price and service. Top notch Texas company.
Fantastic Purchase. This CMC Tactical Drop-in Trigger is great. Put it in my DDM4-v7 and it is a 100% improvement. No slack and so crisp it takes no effort to fire. The shipment was received 2 days after ordering and it was well packaged. Thanks guys.
Go easy with the retaining pin
Go easy when tightening the hex screw on the retaining pin. The trigger housing is held in place with retaining pins that are secured with hex head screws on both sides of the receiver. They conveniently give you two small hex wrenches to use as well. I tightened it a little too hard and ripped the head right off while leaving the threads one the retaining pin. Called Primary Arms and they got me in contact with CNC. They sent me a whole new retaining pin set for free. Called Fri, got pins on Tuesday. Trigger is very nice. Smooth, super short uptake, crisp break. Very nice. Thanks PrImary Arms and CNC

great product, great service, same as always 2 thumbs up
Very good trigger -
Have to get used to it - I have other 4# triggers but this one has zero uptake and pop - got this cartridge style to help me 'fix' an 80% that I measured once and cut twice... and so far so good! Covers my miscalculation...

I ended up going to the store to pick up my order and every one there was very friendly and very helpful! I ended up getting a few more things while I was there. I will going back for sure.
What a fantastic upgrade to my rifles
I got 3 of these to go in my rifles and I am extremely pleased..easy to install and to remove for cleaning via the supplied take down pins.Plus....I really like the feel of the straight trigger pull levers on these triggers!!!!!
I have order from primary arms several times and have never had a bad experience. As far as the products they sell they are top quality and should anything happen to it primary arms costumer service it top notch.
by Tahir Goodman
I received my order 2 days from processing. Also received a courtesy call to make sure I was ordering being that billing and shipping weren't the same. I think it was a cool safety measure. The trigger is awesome. Very crisp no take up. Definitely better than the geissele. If I build another AR I definitely will be building another. I have a few buddies that will be ordering soon
by John B
I was kind of hesitant about this trigger because of the price. Glad I went ahead and bought it. Zero creep and perfect snap. This trigger will always out shoot my skills.
GREAT TRIGGER IMO
by VICTOR MESINA
I`m no expert, but I upgraded my stock trigger that came with my aero precision lower and boy what a difference. Comfort, smoothness and the click just perfect. Price is not so bad especially for beginners like me. Easy install and cleaning. And works with KNS anti-rotating pins. But this one came with anti rotating pins already.
by Andrew burnham
Love this trigger very easy to install comes with anti walk pins break is super clean and crisp no noticeable creep or slack and over travel is negligible all around can't be the price for this probably one of the best investments for any ar also customer service was amazing and because of such I have since stopped using a competing company
by Jerry Zwolen
Putting this in all of my past and future AR builds. Love the flat trigger fell and puts it a little forward for larger hands
by Lonnie Hopson
Really fast shipping, as usual! The CMC trigger takes about 5 minutes to swap out. I have only been to the range once. The difference between stock Colt trigger and the CMC is amazing. Crisp break, quick reset and follow up shots. HIGHLY recommended!
CNBC trigger for my AR
by Roger fortun

Thank you Primary Arms for a great deal on this beautiful triggers!
by Justin Miller
The flat 3.5 pound single stage is ridiculously sweet. Get one!
CMC AR-15 Trigger
by Kevin Williams
The installation was very easy. I really like the flat trigger. The pull weight averages 3.4 LBS which is a great improvement over the stock milspec pull of just over 8 LBS. I would recommend this trigger. Other than the shipping, which I feel was a bit high for such a small item, I am happy with my purchase.
The only way to beat a CMC Tactical Drop-In Trigger is to offer it at a good price and have quick shipping. Well done CMC and Primary Arms.
Simplicity and sexy
This CMC trigger is just spot on the best bang for your buck!! It's got a great warranty, it's 100% drop-in ready, and most importantly it functions like a 300$ trigger. No creep, the reset is just insanel on this thing. Try it, you will not regret it. Thank you to Primary Arms for having it at the best price and of course shipping to my house as if I live next door. You guys Rock!!
CMC Drop In
by K. W.
This is my 7th CMC trigger purchase. Not one complaint or failure yet. My first one has over 5000 rounds through it, has been dropped in the snow, dirt and mud. I have since recommended to many family and friends. I can also tell you I have put over 20 of these triggers into guns I've built and still yet to hear a complaint. Just a fantastic American made product from a Texas Company with an outstanding price tag that won't burn a hole in your wallet.
this is my favorite trigger to date. the take up, the break, and the reset are all spot on. can't say enough good things about PA and CMC both.
