Need to know what AR triggers work well in CMMG build?

[Member 34319]

So my cassette trigger by Aim Surplus no worky worky with the CMMG upper I put together.

Before I go down the rabbit hole to find one that works I figured I'd ask here.

Which trigger you got that actually strikes the rim well enough at at least a 90% success rate or higher?

I've had success with an ALG/ACT, Larue MBT, and the PSA polished AR trigger using a CMMG conversion in a dedicated .22 upper assembly. I've had success with both standard Aero Precision and RTB slick side uppers.

I've read that others don't seem to be having luck with cartridge type triggers/fire control groups with the conversions.

And with the mil-spec design you have the option of swapping in an extra-power hammer spring if needed.

As said above, take your pick. IMHO the ACT is no longer the trigger it used to be with NIB coated triggers from other shops equaling or bettering them (like the PSA).

But, what is "no worky worky" with your current trigger?

I was going to suggest one but I just realized this is a rimfire rifle.

I haven't tried them on a .22, but Hiperfire have the hardest hitting hammers of any of the AR triggers I've tried.

Good customer support too. They'll tell you if their stuff won't fit your application.

These two worky worky like a charmy charmy for me. Various brands of 36gr, 38gr, and 40gr with 1200 fps or more and no hiccups. That said, it does need to be clean and wet or it can stovepipe.

Then the "Grip Screw Trick" and the budget-tuned AR trigger is complete.

There's also the 50 cent method, but the above is a little more convenient.
And it's dropped from $18 to $9 so that's nice.

Haven't tried this yet. It's obviously cheap, but is it actually worth it?

It works.
It gets the trigger/sear closer to the "tripping point".
Not all triggers need it.
And you have to be smart about how you set it up, so you don't end up with an unsafe firearm.
Loctite your final setting.

Running an Elftmann Match trigger in my dedicated CMMG 22lr with zero issues related to the trigger. Only issues I have run into have been related to lack of cleaning and those are still few and far between.

 

[PiratePast40]

When people say they have a "dedicated CMMG upper", are they saying that it's an upper manufactured by CMMG, or an upper with a CMMG BCG/conversion and barrel designed for .22 LR?.

Yes to both

Copy that, thanks

LOL, OK. To me, a CMMG upper is one manufactured by CMMG.. Adding "dedicated" to it makes no sense.

I think the "dedicated" might come from the full, 22LR upper vs. the CMMG "kit" that uses the 5.56/.223 barrel.

CMMG does make (or at least did) a complete 22lr only upper

Yes this ☝☝☝

Maybe they just really like it and are ready for a long term commitment.

Would the reduced springs not cause more striking issues? Or is that to aid in cycling?

Sorry everyone I completely left out that this is a 22lr upper.

Current issues are not cycling issues. Striking issues. I'll get click, rack CH, check case, 0 marks on rim. At times I can run the trigger fast and get a handful of bangs in a row. If I go slow, definitely no bang, no rim mark.

Ill swap the thing around on other SBR lowers to see if the other triggers I got help.
