9mm AR15 Trigger

The 9mm AR15 Trigger is easily where the most confusion lies with the 9mm AR platform. My own research was met with a lot of “Should work” , “Most 2-Stage” and similar vague answers. One of the problems is most AR15 TRIGGER manufacturers have not tested their triggers in 9mm AR15 rifles. The other problem is there are two different kinds of 9mm AR15 BOLT CARRIERS, ramped and un-ramped. We will get into specifics below.

I would like to take the mystery out of the 9mm AR15 TRIGGER. Please use the button below and share the specifics of your build.

Note 1: I use the term “BOLT CARRIER GROUP or BOLT CARRIER” which is not entirely accurate when discussing the 9mm AR15. Technically speaking the 9mm AR15 utilizes a “BOLT“. I use the term “BOLT CARRIER GROUP¬† or BOLT CARRIER” because that what many shooters are used to referring to in an AR15.

Note 2: This page is a discussion of AR15 HAMMERS and AR15 TRIGGERS in 9mm AR applications. The conversation gets more complex when a .223 5.56 AR15 UPPER RECEIVER and a 9mm AR15 UPPER RECEIVER will share a common LOWER RECEIVER. That’s a topic for a different day and page.

AR15 TRIGGERS with a “Rounded” M16 profile are required for 9mm AR15 RIFLES with RAMPED BOLTS and 22lr AR15 Rifles.

CMC TACTICAL TRIGGER

While the CMC TACTICAL TRIGGER for AR15/AR10 rifles may not be the absolute best available trigger for the AR15 platform. It is in my opinion the best value in quality AR 15 TRIGGERS and is able to go toe to toe with triggers costing $100 more. The CMC TACTICAL TRIGGER will exceed the expectations of all but the most discriminating AR15/AR10 shooters.

The CMC Tactical Trigger Group is a completely self contained, 100% drop-in fire control group upgrade for the AR-15, LR-308 and AR-10 rifle platforms. Building on the original Super Match design, the double patented Tactical Flat or Curved Trigger design yeilds truly remarkable and unprecedented trigger control, trigger feel and accuracy, while also the retaining the rugged reliability of a Mil-Spec trigger group. Trigger pull is factory pre-set at 3-1/2 to 4 pounds, and is not user adjustable. Fits most standard Mil-Spec lower receivers with .154″ trigger and hammer pin holes.

  1. Gunsmiths: patented one piece assembly installs in minutes. Check for safe and proper function, you’re done!
  2. Installation of the trigger group is quite simple: insert the one piece assembly, install the supplied over-sized pins. No screws to adjust or worry about coming loose at the worst possible time.
  3. No cheap tricks or compromises: Full strength rocket wire springs for fast lock-time and reliable discharge with factory or military ammo. 
  4. Tolerances of +/- .001″ for all engagement surfaces. Hammer, trigger, disconnector and pins are made with the highest grade, hardest, longest wearing materials available. The assembly is contained in a high grade 410 stainless steel housing.
  5. Factory tuned for a superior trigger pull with minimum take-up and over-travel. Typical quality we’re famous for.
  6. Fits Mil-Spec receivers. Available for small pin receivers only at this time (standard .154 holes).
  7. Not recommended for use in 5.45 x 39
