Anyone have one of these? I was thinking of buying one but they look too good to be true.

I want to say that SMGLee had one. I'm pretty sure he posted about it a while ago, but it didnt run up in the search. You might try and IM him.
ETA: After searching some more I still didn't turn up much, but I didn find some info on the JP drop in that might interest you www.ar15.com/forums/topic.html?b=3&f=118&t=205512 |

pspencer,
A friend of mine who owns a gun shop said he played with it at the SHOT show. He was very impressed with overall construction and how "crisp" it was. I put my order in yesterday. There is a 3 week backlog due to demand. |
|
Thanks for the quick replies...now I just have to choose between the JP or the McCormick. Hopefully Gun Tests or some other reliable magazine will run an article on them.

Just an update in case anyone is looking into this product, I ordered mine in October (the McCormick version) and finally got it yesterday. While I am by no means an AR-15 armorer, it took less than 15 minutes from start to finish to get it installed. Beware though, it comes with no instructions for installation so if you don't have at least a basic familiarity with minor disassembly you might want to take it to a gunsmith. As far as the quality, etc. I could not be happier. I ordered the single stage curved version, it is quite crisp and light. The unit seems very sturdy and well built. I installed it in an Armalite Carbine and the difference in the trigger pull is remarkable. Long wait but well worth it.

OK I finally got to the range and tried out the trigger. It brought my groups at 100 yards down from 3.5" to about 2.5", shot from a supported seated position with iron sights. I would really like to see what it would do with a decent scope. Faster shooting at 50 yards was also much easier, my range does not allow rapid fire, so I had to stick with double taps. I'm very satisfied overall.

It took me about a month to get the flat single stage I ordered direct from CMC. They had plenty of two stage curved triggers at the time but I wanted something different. I am real happy with the CMC flat trigger. It was super easy to install, and it was light and crisp with very little if any perceptable take up. It was for me worth the wait. |
|
|
i just ordered one of the curved trigger two stage from denny yesterday morning.
got an email later that morning that it had shipped out |
|
I tried them at SHOT. I didnt think the pull was any better than an Accuracy Speaks, but the installation is certainly easier. Something that concerned me was the guy working the Chip McCormick booth said the hammers would eventually be MIM.

I HAVE A 2-STAGE CURVED IN ONE OF MY LMT LOWERS. IT IS EVERY BIT AS GOOD AS (IF NOT BETTER THAN?) TWO OF MY THREE KNIGHT'S TRIGGERS, I DO BELIEVE. LOTS OF ROUNDS DOWNRANGE WITH NO PROBLEMS.
(THAT ONE KNIGHT'S TRIGGER, IN MY SR-25K, IS NOT LIKE ANY GAS GUN TRIGGER I HAVE EVER FELT.) YES, WE HAVE THE CMC TRIGGERS BACK IN STOCK. BUT HALF OF THEM ARE HEADED TO THE AREA 2 THREE-GUN MATCH IN BAKERSFIELD, CA, WITH PAUL. WES GRANT M.S.T.N. |

Nope. And you shouldn't be using such a light trigger for full auto anyway. |
|
|
Any updates on these triggers with more range time?
Would these triggers be considered tactical (i.e. duty/service)? |
|
AS LIGHT AS THEY ARE AT 3.5 LB, I WOULD NOT THINK THEY WOULD BE APPROPRIATE FOR SERIOUS SOCIAL INTERACTION, OTHER THAN PRECISION APPLICATION.
BUT MCCORMICK DOES OFFER A 4.5 LB VERSION THAT WOULD BE SUITABLE. WES GRANT M.S.T.N. |
|
I checked them out at the shot show and was impressed. I ordered one and should have it relatively soon for my SPRish build.
|
|
I've got one in 243 WSSM AR. It is a nice trigger, but not as clean and crisp as the JP single stage in my experience. I had to wallow out the holes in the receiver in order to get the oversize pins in too.
|
|
|
Just Great! I was seriously considering buying one of these triggers when I found out on a retailer's website that they don't work on any Colt rifles with the block. That should only eliminate about 30% of the market out there....including me!
|
|
What kind of pins come with these? Std. pins or "E" clip type pins. I ask because Brownell's lists them with "E" clip pins, which I would'really like.
|
|
"E" CLIP OR WHAT OTHERS MIGHT REFER TO AS CIRCLIPS.
AS THEY ARE DIFFERENT THAN WHAT I AM USED TO SEEING, I INITIALLY HAD MY RESERVATIONS ABOUT THEM. AFTER USING THE TRIGGER WITH THESE PINS FOR THE BETTER PART OF A YEAR, I AM OVER IT. ZERO PROBLEMS WITH THE PINS. KEEP IN MIND THESE PINS ARE NOT THE PIVOT POINTS FOR THE CMC FIRE CONTROLS. THEY SIMPLY SECURE THE MODULE IN THE LOWER RECEIVER. MORE IMPORTANTLY, THE (2-STAGE CURVED) TRIGGER IS GREAT, PROBABLY THE BEST I CURRENTLY HAVE IN AN AR'. OTHER CONTENDERS IN MY LOWERS: 2X KAC 1X ACCURACY SPEAKS 1X LMT THESE ARE ALL GOOD TRIGGERS, OR I WOULD DUMP THEM. THE EASY TAKE-UP, CRISP BREAK, AND MINIMAL OVERTRAVEL OF THE CMC MAKES IT MY TOP CHOICE. WES |
|
Wes, will the CMC unit fit in a newer Colt lowers that have the sear "block" machined into the lower?
P.S. do you have any 2-stage curved units in stock for the Colt large pin? |
|
The Chip SS triggers feel very much like a SA or Kimber 1911 trigger. No takeup, very smooth short travel and no slack after ignition. Light trigger but nice.
|
|
Interesting, I just tried both of my Kimber triggers. They both have a light first stage (takeup) and a crisp second stage. This is what a good 2-stage should feel like. |
|
|
I got mine today.
$128.96 from Brownells. installation was easy. oversize trigger pin did have to be tapped in. Much easier installation than an Accuracy Speaks trigger. Anyone know what the hammer spring weight of the CMC unit is? is it relieable with hard military primers? |
|
The only "peculiarity" on the McCormick trigger is that it allows you to put the safety lever to SAFE when the hammer is resting on the firing pin. BC cannot be pulled back with hammer on pin and lever in SAFE. I noticed this because I usually store my AR's with the hammer resting on the pin with lever on FIRE.
Other than that, the McC is one super fine trigger. I installed the single-stage CURVED in an M4gery... It is light but oh so sweet! Easy install but pins took some effort as they are slightly oversized. Not worried about this as it is just a Mega lower and the McC will probably stay there for life of rifle. Rmpl |
|
Interesting. I had not noticed that. I just checked mine dconfirmed, yes you can put the selector in the safe position with the hammer uncocked. BTW; I ran about 75Rounds of Black Hills and Hornady ammo through mine the other day with no FTF. I fdont know what weight hammer spring CMC used, but its heavy enough for comericial primers for sure. Still have to try ammo with miltary primers. |

CMC triggers use full-weight springs, so primer ignition should not be a problem. Wes and I shot many thousands of rounds through these before we started selling them (I do wear a belt and suspenders from time to time, but only as a load-bearing device). In over a year, the only issue has been an early batch of single stage triggers that had bad disconnector springs. One pull, two rounds was a common occurance. (Actually a nice feature if it could have been made consistently! ha ha ha... CMC corrected the issue with the proper spring and that was that.
The best feature for me is that every one is the same. You can put them in several lowers and they will feel identical. Since the pivots for the trigger and hammer are inside, and not on the receiver pins, there is no gritty feel, no need to polish pins, etc. I have had two installed for better than a year with around 10k rounds through the pair and the c-clips have done no damage to the receiver finishes. Since they don't rotate, and the clips are a few thousandths away from the receiver sides, I don't see any issues with them, even over a long time. |
|
I agree, the c-clip is a non-issue... pin is tight in receiver, c-clip sits away from receiver finish, offers very minimal places for a hangup on something...

Great pics!!!
Wonder why your safety lever would not and mine and anothers would move to SAFE with hammer up? I have a Mega lower with a RRA lower parts kit... Maybe safety lever is different somehow? So, what do you think of your McC trigger? Sweet, ain't it... Even if the SHTF and we enter TEOTWAWKI, I don't think I would need a heavier pull trigger in there... With the McC there is NO error due to gritty, heavy triggers... Maybe a long drop or super-heavy jolt may cause gun to fire, otherwise it is solid. Plus, rifle should be in SAFE until you are actually aiming rifle to shoot anyways... Rmpl |
|
Mine is in an Oly lower with Oly parts kit. Safety will go on with hammer uncocked. |
|

i was wondering the same -- maybe a question for the folks at CMC.
have not put any rounds downrange yet but it sure feels *really* nice.
i have an uber-KISS plain jane M4-gery for SHTF/TEOTWAWKI; the pictures above are of a RECCE-ish target rifle with big glass on top. that said, just based on dry firing the CM trigger, it is fairly light but not scary-couldn't-be-used-in-a-pinch light. the reasons i got the single stage curved CM trigger assy for the RECCE-ish rifle were that a) operation etc is consistent across both my ARs, and b) i'm not looking for the last tenths of an MOA that a two stage straight may provide. which brings me to...
hence why i would definitely inquire with CMC about the selector lever issue you note above. i always looked at the AR trigger/selector/safety system as a little foolproof. if the hammer is not back you can't safe it. and, correspondingly, when it's is safed with a round in the chamber you are ready to rock and roll just by moving your thumb a quarter of an inch. with the CMC trigger installed in your upper, as you described, it's possible to be in a odd situation -- round in the chamber but hammer forward, with selector on safe. there's movement, you acquire target, flip safety off, pull trigger, and... nothing. it would appear to me that it's somewhat difficult to get the rifle in that exact state, but, given the opportunity, every once in a while good ol' Mr Murphy will pop in to say "Hi, I'm here to screw up your day!". performing SPORTS in a hurry will correct from this mode. ar-jedi |

Dumb question that I haven't seen answered:
What happens if you use the normal AR pins with the CMC drop-in, instead of the oversized pins with the C-clips? |
|
They fall out. |
|
|
jack, the OEM pins have grooves in them which mate with the OEM trigger springs. that is, spring tension keeps the normal pins in the receiver. with the CMC assy, all of the trigger components, including the various springs, are inside a small enclosure. there is no spring tension on the normal pins if you put them back in to the CMC trgger assy; just a bit of friction fit. hence, they will eventually work themselves out when shooting. ar-jedi |
|
|
Thanks, Ar-Jedi, that's a good point.
I believe that both the CMc and the JP drop-ins have non-rotating bushing shafts that just "ride" on the pins. The trigger and hammer then rotate on the outside of the bushings. Pin-walk is mainly due to the rotation of the hammer and trigger, and friction couping that rotational motion to the pins. Since the CmC and JP bushings don't rotate, there's nothing that would work the pins out, unless the whole assembly wriggles a little. I could be wrong about the CMc and JP having non-rotating bushings, it's just what they look like in the images. In any case, I could try the normal pins and, if I get pin walk, change them out for the larger pins with clips. I have a non-drop-in JP trigger group in my #1 AR now and had to use a pin and clip on the hammer to keep it from walking (it makes nice 2 and 3-shot bursts when the pin slides out a little!!). I don't like the way it looks, and I catch my cleaning cloth on the clip. |

I think this deserves a bump since alot of us are buying these triggers!
|

Great pics AR-Jedi!
I've been looking at the CMC triggers for a while but have been waiting to see if they live up to the hype. Looks like they're good to go. The only thing that still bugs me about them are the pins being slightly oversized for some lowers and the e-clips that hold the pins on. |
|
That bugged me too, which is why I contacted Denny and purchased a KNS anti rotation pin set to go with my McCormick 2-stage curved trigger. Yojimbo, I'm really, really happy with this setup. I have no problems recommending it to anyone. Yeah, you're going to spend $29 for the pins, but I think the cost to be well worth the price of admission. |
|
|
TFS, Yes, I've wondered about using the KNS pins the CMC trigger. It's good to know that they work well together, I may need to try this combo myself... |

|
i just checked my trigger (two stage curved) and the safety does not switch
bushmaster lower and lpk's also does anyone have both single and two stage? which one would be better or preferred? |
|
I just got my CM yesterday and all I can say is wow! There are two things that all my ARs will have, a Sierra SPR pistol grip and CM trigger!
I was worried about the oversized pins too but once I got them in I was no longer worried about it. Those pins are not going anywhere. |
