 Drop-In AR15 Match Trigger Module from the Chip McCormick CorporationFor more information please check out this link www.ar15.com/content/products/triggers/mcCormick/ Or the Chip McCormick Corp Website - Check out CMC's SATISFACTION GUARANTY https://www.chipmccormickcorp.com/ From the staff at Chip McCormick Corp. (CMC): DO YOU EVER ASK YOURSELF; IS MY RIFLE A SERIOUS TOOL? If it is a serious tool then you should have defined what its mission and usage is intended for? The currently available CMC AR15 single stage triggers are designed with primary focus on reliability, then an enhanced trigger pull that is as crisp and light as we feel the edge on reliability will allow, and all with very simple installation. Since introduction of our upgraded Generation 2 single stage triggers in Jan of '06 the reliability factor has proven out to be completely effective. For those shooters concerned as much or more with reliability, especially under all conditions of usage (repeat, under all conditions of usage), the CMC trigger is worth serious consideration. The CMC website explains in detail why we think our product will accomplish its design objectives. And the numerous CMC triggers being used in serious tactical weapons both in the US and overseas makes it clear that a lot of people have the same priorities as those designed into our triggers. Sure, if on single stage triggers you reduce total engagement and reset to bare minimums then perhaps somewhat lighter, crisper trigger pulls can be accomplished. And if those characteristics are a primary focus then reliability cannot be, in our humble opinion. But ultimately, we think the key to making the right choice of product is to clearly define the mission and usage for your rifle, list your priorities in order of importance, and then understand more about WHY certain triggers have different characteristics? Then you won't be disappointed....at the least convenient time! DVC |

Have the issues with doubling found in the early units been completely eliminated in the "gen II"?

From the Staff at CMC:
Since the initial introduction in January of 2006, of our newest Generation II single stage trigger modules and after many thousands of units sold, we have not had one single report of any doubling whatsoever. CMC Staff |

How do I tell the differance form the old and new models(visually)?

Good question. I am also in the market for a nice match trigger, and researching different models before I buy one. |

The easiest way visually to see the difference is the hammer in newest Gen II trigger modules is lightened for reduced lock time, with recesses in the sides of the hammer behind the striking face rather than appearing perfectly flat. Since 2007 is the first year we've ever been able to completely keep up with demand on this product, it is very unlikely any source for supply would still have any of the old Gen I's remaining in their inventories.

Was the issue with the selector being able to move into the SAFE position while the hammer was forward worked out? It is not something that would normally occur when firing, but when people were looking at the trigger and had the upper hinged open or just cycling and dry-firing it there was more than one time when someone would dry-fire it to feel the trigger and then move the selector to the SAFE position. Someone else or even the same person would then try to pull back the charging handle and cycle the action. I couldn't see any damage to the trigger, only because I quickly stopped them whenever I saw it, but it couldn't be good for it.

TACO, With the Gen II trigger modules (introduced in Jan '06) the safety selector can only be engaged when the hammer is in the "fully cocked" and ready to fire position. CMC Staff |

any plans for a M16 version?
|

Posted: 8/25/2007 5:31:55 AM EDT
[#13]
M16 trigger module? Possibly! We have received serious inquiries from various branches of the military. With no screws or adhesives to ever fail, our totally self contained design interests them because anyone in the field with minimal tools can quickly swap out the trigger group in case of a part(s) or mechanism failure. Removal and re-assembly for basic maintenance is very quick and simple as well. According to the information we’ve been provided with, only a fully trained gunsmith is allowed to do any work whatsoever on the standard trigger group in a military issue M16. CMC Staff |

Something to consider might be a rounded top hammer which would function in the greatest variety of ARs, as well as (possibly) future weapons which use the AR trigger group (ie, masada).

Not sure I'd call a unit-level armorer a 'a fully trained gunsmith'. Its usually a 92Y--Unit Supply Specialist. Even a 2nd echelon 45B--Small Arms/Artillery Repairer is hardly 'a fully trained gunsmith'. |

Thanks for the clarification. Perhaps we could have said it better by saying, our understanding is that the average soldier is not allowed to do any removal or installation of their standard type trigger group due to complexity. And that is why our module has caused intrigue, because it only requires installation or removal of two retaining pins to remove and/or replace the self contained trigger group module. Very easy for ongoing maintenance and lubrication, especially in extreme environments. Also, our design requires no screws (which can loosen) for retension.

I have one of the earliest versions of the flat single-stage CMC Trigger. I bought it a long time ago when they were first released but I have never used it. Is it still safe to use? Or are these Gen I single stage-triggers dangerous? I think I paid $175, it would be a bummer not to be able to use it.

Very few of the Gen I's had any problems. The overwhelming majority of the many thousands out there always have worked just fine. However, if you would like to send yours back to us we will be glad to check it out and re-qualify it's function. Or, if more convenent, you could first have a qualified "civilian" AR15 gunsmith who might be in your area, check it out. If there is any question remaining after that, then send it back to us. Whatever works best for you? CMC Staff |

so regarding the m16 trigger group, there are lots of us who have our own M16s. most of us aren't entirely satisfied with the original triggers.
you would definitely have some customers if you made a M16 compatible trigger group. i'd definitely be in for 1 and volunteer to be a tester if you need one. |

Thank you for the response. It appears to work great with all of my own quality checks. I have just recently finished the build. It's a top of the line rifle with many expensive parts that took years for me to accumulate. If there is a problem I will take you up on it and send it back in. |

A drop in full auto trigger group would be a great benefit to those of us who have a registered drop in auto sear and several lowers to put it in. It could help us stay in compliance with the NFA regs. I would sign up for one today.

I asked for an M16 version 3 years ago at SHOT Show, then I asked two years ago at SHOT Show. I had to skip this year, but I will be back at their booth asking for one again this Feb. in Vegas at '08 SHOT..... Hopefully I can nag enough to get it done.

DO YOU EVER ASK YOURSELF; IS MY RIFLE A SERIOUS TOOL? If it is a serious tool then you should have defined what its mission and usage is intended for?
Two stage vs Single stage? That one seems clearly as much about personal preference as it is actual function and the mission profile for your rifle. We've made both types and will again soon. Here is some food for thought on the subject based on some of our first hand experiences: 1. Have you ever seen someone under stress and/or pressure in a rapid fire situation have "trigger freeze" (not let the trigger move far enough forward to reset)? If that worries you which type trigger, 1 or 2 stage, do you think you might be more or less likely to do that with? 2. Using a 2 stage trigger, stressful/high pressure, somewhat rapid fire situation requiring precision; you fire, let the trigger reset and then stroke from the 1st stage right through the 2nd stage without intending to? A.D.? Funny things happen under stressful, high pressure situations. 3 The temperature is very cold and you are losing feeling in your fingers. Would you rather the rifle fire as soon as the trigger moves (1 stage) or would you have enough feeling left in your finger to still confidently pull through the 1st stage and stop on the 2nd stage of a 2 stage trigger? A.D.? |

Civilian M16 People, It's not that we are trying to dodge anything. To be frank, we haven't been under the impression that there would be a high demand for "legal" drop-in M16 triggers in the civilian sector. Among other factors to be considered in a prospective manufacturing project is, economy of scale. High volumes lower cost. Low volumes increase cost and miniscule volumes sky rocket cost. So you folks that know the most about this prospect, please share your views with us about what is out there for this product you are asking us for? Thanks, CMC Staff |

The options for better triggers are slim to none when it comes to the M16.
There are a LOT of M16's in private ownership, there are several members of this board that own more than one. I've just got one, but would definitely pay for a decent trigger, drop in or not. To be quite honest, I don't care whose name is on the side of it. I just want one from somewhere. If it's CMC that makes them, that's great, another awesome CMC product in the collection. (I use CMC magazines exclusively in my 1911) A lot of people make the assumption that M16 owners just go out and do mag dumps. Which, yeah, sometimes that's fun but don't forget, it also has the option for semi auto, thus being just as useful for precision shooting as an AR, but with much more limited performance due to the lack of a quality trigger. It all boils down to this. If you make them, people WILL buy them. You may not make any record profits off of this item alone..but remember those of us who have M16's also have ARs, 1911's, and several other guns that you guys DO make parts regularly for.

I have two M16's and I would buy at least 3 M16 drop-in units so as to have one for a spare. A better trigger, plus the simplicity of the CMC trigger unit would be something great to have.
I've bought a lot of CMC 1911 parts in the past; I think adding a good M16 trigger to your product line might not be a huge prrofit maker, but even if it just pays for itself it would be a major win for CMC in the NFA world, where a lot of folks with significant disposable income live

I own a registered drop in auto sear and would love a drop in trigger group to go with it.
With a RDIAS, it gives me the ability to have a variety of lowers set up in different configurations and calibers. To stay in compliance though only one lower can be have a complete parts set in it. Lowers with M16 parts in it that are not with the registed sear are considered unregistered machine guns. One of your trigger groups in an M16 configuration would solve this dilema for me.

A drop in M-16 trigger to go with my RDIAS would be a sweet setup. It would also result in me swaping my AR-15 triggers to CMC units so I could switch things around easily. I think for every 16 unit you sell it would result in several AR sales as well.

I've got 1-stage curved in both my SBR and varmint builds. Is the 1-stage curved curved also compatible with a 9mm bolt carrier groups? Been contemplating a pistol caliber is why I ask.

I just installed a single stage curved CMC trigger group in my carbine, replacing an RRA 2-stage. The pull weight comes out between 3 and 3.5 pounds, and it's very smooth. There is no take up and the total travel is around 3/32" - about 2/32" to release and 1/32" overtravel. While puliing the trigger very gradually there is smooth consistent creep, but when pulled normally it feels more crisp.
My only question is about the safety. With the hammer cocked and the safety engaged, the trigger will pull maybe 1/32". Clearly, there is enough sear engagment that this is not a safety problem, but I was wondering it it should be more like a 1911 safety - which is fit so that there is zero sear movement when the trigger is pulled with the safety engaged. Should I try a different safety? So far I am very happy with this trigger, especially when you consider the fact that it is a complete drop-in, does not have or need any adjustments, and uses full-power springs to ensure reliable ignition. Also - when is the two-stage version going to be available? |

We want our customers to be a happy as possible with their investment in our product. In that regard, if you feel your trigger module is not appropriately compatable with your rifle, please communicate with us and we'll make every effort to resolve your concerns. We intended to re-introduce our 2 stage trigger modules, with some cool new upgrades, late this year (about right now, actually). But logistics had dictated that we delay that introduction to remain focused on supplying the increasing demand for our current single stage models. CMC Staff |

We don't like being stuck with something we didn't really want anymore than the next guy. Most of us here at CMC prefer the "Flat" style triggers in our rifles as well. You apparently caught us during the period in between production of our patented "Flat" style triggers. With no "Flat" triggers in stock we obviously thought it best to send you the only model available at that time, the curved style, so your rifle would be useable. But if you still desire to have a "Flat" style single stage trigger you won't have to wait much longer. We should have the next run of "Flat" style triggers completed in a matter of weeks. Contact us in about 3 weeks to make arrangements for replacing your curved trigger with one on the new Gen II "Flat" models. We apologize for any inconveniences, but hang in there with us and we'll get you back where you want to be. CMC Staff |
