I have a CMC trigger that I would like to put into my New Frontier 9mm lower.  I have a New frontier upper with a Kaw Valley Precision standard 9mm bolt and KVP match barrel.

Will the CMC trigger work on this gun?  I have heard that certain drop-in triggers don't function properly on 9mm AR PCC gun.

Thank you,

Chris

Tried in mine with a KVP bolt & it would not reset the trigger. CMC trigger will work with my Taccom BCG.

Try it and see is all you can do.   I like the single/flat CMC triggers and dropped one into my PSA PCC and it didn't work, wouldn't reset.

And for reference, a Timney works in mine, and the Velocity started doubling after around 500 rounds.

I have a CMC single stage that works in my KE Arms lower with a NFA upper and modular bolt.  FWIW, I had emailed them when I first had it built, and this was their reply...

 

"With our AR10/15 triggers they're not typically meant for the 9mm platforms, however we have customers that have zero issues, while others experience reset issues. If you are not experiencing reset issues, you're one of the lucky ones! There's nothing specific to analyze if you're not having an issue."

 
They had indicated at the time (October last year) that they were going to be developing a PCC-specific trigger, but I still don't see one on their website.
 
I am also not seeing any deformation on the rear of the firing pin with this trigger.

I'd drop a note to aircooled6racer - he seems to have a LOT of experience

with what will work and won't work with a PCC    :)

Same here. CMC in a PSA and it wouldn't reset. A lot of folks having great success with the Hyperfire. I'm saving my pennies for one of those.

I had the CMC trigger with NFA bolt and it didnt work, same with Sprinta bolt. My buddy has the exact same set up and his CMC worked with his speinta bcg.

I just pulled the CMC Flat trigger out of my PSA lower. Hammer following/Not Resetting. Put a regular trigger back in and it works. The CMC works in the standard lower i swapped it into. The funny thing was I had it at the indoor range twice last week and it worked both times. Last night at the match it started taking a dump.

 

Just going to put some JP springs on the original trigger and save up for the 24C

That would be awesome! I've seen other posts going back to early 2017 of the same. I just want to have the same trigger in all the rifles. 😎

I really recommend the same trigger across platforms. If you’ve already got a CMC that you like, I’d recommend yanking that one and trying it out in your PCC.  If it works, LEAVE THAT ONE IN THE PCC and buy a new matching one for your AR.  That's basically what I did with mine (Hiperfire 24c) and it’s a success.

I have a glock lower & CMMG Bolt on my backup PCC.  This was my first build and I have a CMC trigger in it.  My gunsmith welded an extension on the hammer and then heat treated it in the oven.  It has lasted so far and the only issue I had was the disconnector I guess.  He said he sent it back to CMC and they put a new one on.  At the same time they were impressed with the extension he put on.  If you do decide to extend the hammer I highly suggest you get it heat treated so that it will last.

I already went down the CMC Flat rabbit hole... Ak, ar15 x 3, AR10. A little too late for me unfortunately.

 

I put a standard trigger and hammer in with JP springs. It has worked so far minus it being dirty and jamming. Cleaned up it works great.

So I guess the caveat I should’ve said was: put a really good, matching trigger in all of your guns! Polishing up and using J.P. Springs in the regular AR trigger actually works relatively decent but it’s nowhere as nice as an actual match trigger. I really like the hyperfire but that doesn’t mean somebody else can’t find a better one. I wouldn’t mind trying an Elftmann.  Timney always gets good reviews.  None of the really good ones are going to be cheap.

Don't see much love for the Elftmann AR9 trigger here.

 

Is it just because of lack of exposure, or are guys having problems?
