The CMC Single Stage trigger features a non-adjustable flat trigger bow with a 3.5lb pull that breaks like glass. It has almost no take-up and extremely short reset to make follow up shots fast and easy. The flat trigger increases surface area for you to rest your finger on and improves trigger control and consistency in your pull. The hammer is lightened and uses a high-power Rocket Wire spring that ensures reliability with commercial and surplus ammunition. The high-power spring also results in minimal lock time, which is the time it takes for the hammer to fall and strike the primer, resulting in much more accurate shots. CMC Triggers have invested in a new production and tooling setup that incorporates advanced techniques that help to reduce manufacture time and cost while still providing you with a high quality, reliable trigger that is affordable.

Assembling an AR-9 carbine is extremely similar to the AR-15 assembly process. Which includes some of the same frustrations such as installing the takedown detent and spring or trying to put the trigger together. CMC Triggers saw a need to improve on this 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, or just general fun at the range. It has an extremely light and crisp 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.

Awesome trigger from an awesome dealer

Ordered this trigger from Primary Arms and shipping was processed extremely fast and delivered on time. This is my first CMC trigger and without a doubt I am impressed by the smoothness and overall quality of the trigger. Break is clean and reset is rock solid. Will definitely be ordering from CMC in the future, and will continue to order from Primary Arms.

Excellent Performer

I purchased this trigger to replace the stock trigger in a Foxtrot Mike 7 inch side charger PCC. Outstanding trigger. Clean, crisp break with a short, tactile and audible reset (audible not loud). No break-in necessary. Just solid, positive function. 1500 rounds and still going strong. Going to buy two more for other 9mm PCCs.
<br>And, of course, Primary Arms service rocks!! Always fast, friendly and helpful. PA is my go to for parts.

Good product, better price and best shipping and delivery time.

First, kudos to Primary Arms back office staffing. So incredibly quick with getting online orders out for shipment. Ordered this early morning hours on a Friday and received at my front door by 1330 on Saturday. I live 10.2 miles from Primary Arms per Goggle Maps but that shipment is still great. I read reviews about triggers and chose CMC my build. I have other brands of drop in and enhanced trigger sets from top name brands but I picked this trigger based on reviews. A PCC is not a hunting rifle nor are we competitively shooting at any distance. CMC per specs and reviews gave me confidence that I was getting a quality trigger at a fair price and a better price through PA.
