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.

Amazing amazing trigger. Never felt a better one. Maybe they’re out there, but you probably pay double the price. Can’t say enough good things about Primary Arms also. Great dealer, fast shop times, always the correct order.
Better than a High Dollar Trigger Job!

Installed the CMC Trigger in a Spikes Hell Breaker Lower with the Strike Industries Enhanced LPK, and a Hogue Grip mated to a Bear Creek Arsenal Side Charging Upper and 20" 6.8 SPC YHM Barrel.
<br>Trigger Breaks Perfectly. Highly recommend!!!
<br>You can't get a gunsmith to perform a trigger job for less.
Dropped straight into a Del-Ton DT10 and is way nicer than the OEM trigger!
Ordered this trigger after hours online on Black Friday.
<br>Tracking said it'd be here on 11/28.
<br>Today's 11/27 and this trigger's in my Del-Ton DT10 .308 now!
<br>Haven't fire the rifle yet, but can immediately feel the trigger difference!
<br>Now I wish I'd bought two at the sale price! =)
As Advertised and Fits Great in an Anderson MFG Lower
Just dropped this trigger kit into a new 10.5 inch pistol build using an Anderson MFG stripped lower and it was a breeze to install and fit great! The retention pin screw kit works great so no worries about a pin creeping out. Put about 100 rounds through it last week with no issues and the trigger appears to be as advertised with a smooth 3.5 lb pull and crisp break. The flat surface is a new concept to me and appears to help get your finger in the same place every time with a consistent pull. I still like my Geissele triggers but this is a top notch drop in for someone looking to upgrade to a nice trigger for a good price (seen them as low as $99).
Amazing trigger and service from PA!

As always; Great job from PA in sending the merchandise at lighting speed! Great Trigger and was able to snag on Sale so it really made it a steal! As always; great experience from PA and impressed with how they operate!
Best trigger on the market
by Jason -
This was my second cmc trigger and in my opinion it’s the best on the market.
Worth Every Penny
Absolutely worth every penny. This trigger offers great control with very noticable resets.
Fantastic Trigger for the money,
by Deadhorse -
One of my favorite triggers, great break, clean pull, no creep, easy installation, anti-walk pins a must though, havent had any problems with steel cased primers. Probably the best trigger for the money out there.
Worth the price
by Sean -
Very good trigger. I wish that it had set screws to remove any play between the trigger cartridge housing and the lower. Also...not a fan of the look of anti-walk pins, but the ones provided with this trigger are not as bad as the ones with the dog bones between them...just a screw head on the ends of each pin. While at the range, I get some shots that have a noticeable amount of creep in the trigger. No idea how it can go from very little if any creep one shot, to a noticeable amount (wondering why the gun has not gone off yet) in the next one...but this trigger does it. I have not noticed it with the curved CMC triggers I have in other guns. probably has nothing to do with the shape of the trigger shoe, just an observation that my straight shoe has this oddity, and the curved shoes don't.
What else can you say.
by James -
Excellent trigger. I put this trigger on a custom long range AR that I built. Trigger was a great price and is a much needed upgrade from the stock triggers coming with the lower parts kits. Getting this trigger on sale makes it a must for any shooting enthusiast. Simple to install. Should improve your groupings. I have since bought 2 more.
Beautiful Trigger at a beautiful price
by Kyle -
Absolutely love this Trigger. Got it on Black Friday from Primary Arms for the cheapest I’ve ever seen it. Very easy to install, even if you don’t know what you’re doing. Takes about 5-10 minutes tops. I’d highly recommend CMC Triggers to anybody.
Have 5 of the straight and 2 curved triggered stiles. Think I may like them? The smoothest an crisp single stag I have. Even put one in the .308 / 80% just completed.<br>Happy shooting. jp
Best Single Stage Trigger Ever
by Chris -
Had my eyes on this baby for a few weeks until the price dropped then I had to jump on it. I'm absolutely in love with this trigger, no take up, crisp break, short audible reset. What's not to love? Plus the flat blade makes it feel like a lighter pull and the notch at the bottom gives you a spot to consistently squeeze so your groupings are as good as they can be. The fact that you can literally drop this trigger in, push the provided pins in and screw them together all within a couple minutes made it an easy choice. Definitely recommend any of CMC's products, I have the curved blade in another build and it's just as amazing if you're not really into the flat blade still check out the rest of their products. You won't be disappointed and Primary Arm's shipping is by far the fastest and most customer friendly I've seen. Big double thumbs up to Primary Arms and CMC!
My new go to site for sure
by Scott -
I have order from multiple site more often than I probably should but the shipping speed on my first order from PA was so fast I will always check here first. Item arrived as advertised they even gave me the sale price as it went on sale the day after my order
Look no further
by Chuck F.
I have built several rifles with timneys , black rain and geiselles- all good products. Just finished an AR -10 build with the flat trigger-- incredible --- no creep, take up is minimal and it lives up to the old saying that the break should always be a surprise- I like to catch 'em on sale, but they are worth every penny. Put one on a SBR 300 BLK 8.5" and it can cycle abt 400 rpm- super fast. No other trigger from now on- super product- look no further. This is the one item that will turn a $400 slammer into a $1200 tack driver.
Doesn't fit in M&P10 with ambi.
Will not work with M&P10 due to the ambi right side bolt release latch using space inside the trigger housing area. Works great in my 15.
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.
Great product ,price and service
this is my third cmc tactical trigger from primary arms. They all work flawlessly and are great triggers ( break real clean) P/A has the best sale price and great shipping as well.

by James Briant
What a difference when you have a nice trigger. Exceptional feel! Great too, how it simply slips into place as a unit.
by Gregory Schlemmer
Very good fit. I love the way the pins secure with screws.
Nice quality trigger group
by David Yearick
This trigger drops in quick and super easy. Night and day compared to the standard mil spec kit. Currently in my gas piston pistol working with no problems.
by samuel camarillo
What a difference. nice clean trigger pull with no creep. Last thing I needed for my tack driving 20" AR. And of course PA had the thing in the mail less than 24 hours after I ordered it :-)
