Well firearm testing won't happen today. Weather is pretty crappy this morning and have a concert to attend later this evening. Hopefully tomorrow.
I have installed the CMC into a trigger chassis that allows me to do some dry fires. So I have some initial observations.
The trigger itself is pretty nice. Installation was quick and easy. This has the screws that go in each end of the pins. That of course differs with the website at CMC where it states there are no screws. I don't think I'd change these to another type/brand of anti-walk pins as there's no real reason other than maybe aesthetics if that's what's being sought.
Edges are smooth and the straight bow actually feels pretty good. The little hook on the end is not intrusive or anything at all. In fact, the straight bow on the CMC feels better to me than the Geissele SD-E that I had.
I was interested to see how the stainless steel sheet metal housing was going to be. It's actually very nice and formed well. It fit the chassis nice and snug, no wiggling or anything.
The hammer, sear and disconnector design are different and very interesting. Actually kind of cool. The hammer is large with a big flat face.
Takeup was not overly long. It seemed comparable to my AR Gold in length. By contrast the MBT felt longer. These observations are all by feel at different times so I'd have to do measurements to verify. Pull weights between the CMC and MBT felt similar with the AR Gold being the lightest take up by far.
I did have the CMC in the chassis, the MBT is still installed in my Grendel (for now) and the AR Gold in my Creedmoor. This allowed me to try each without having switch out the triggers. It also provided the opportunity to notice other traits I had missed before, more on that below.
After the take up, the second stage wall is hit. On all the it was well defined on all of them.
The break was nice and crisp as with the others with no creep I could detect. Again I could be wrong as this is all by feel.
Reset had a little travel distance. Longer than the AR Gold, but shorter than the MBT. When reset was reached, it was audible and felt clearly being similar to the MBT. The AR Gold is there, but somewhat softer than the CMC or MBT for lack of a better term. The AR Gold is still very noticeable, but the CMC and MBT were more pronounced. This is where I noticed something I hadn't before. The reset on the CMC felt smooth for the distance traveled as with the AR Gold. The MBT, that actually felt gritty. Movement of the trigger back and forth in the region between full pull back and reset felt smoother on the CMC than the MBT. I can't feel much on that AR Gold because it's reset distance is short, real short.
Overtravel was minimal on all, to the point of being not noticeable.
In the end, I like the CMC. I'll get it installed and give it a try. It has made my list of possible triggers to standardize on along with Geissele and AR Gold. The CMC in my eyes (and hands) is well made and functions really well. It being a drop in actually gives it an edge over the Geissele's in my book. Yes the AR Gold is still the front runner for me because the only thing I haven't really cared for with it is the thin trigger bow.
It was actually disconcerting finding traits in comparison that had gone unnoticed. Oh well, that's partially the point of why I'm trying all these triggers and finding what will work best for me. Would I hesitate in buying and paying the cost for a CMC? Nope... No problem at all, seems like a really good trigger and worth the price. If I run into anything during actual firearm testing I'll be sure post any findings.
