New Fostech Echo Issues and CMMG 22 Conversion Auto trip

People have more money than sense

My new echo trigger works just fine and there is no pitting anywhere. The metal work looks great and its smooth as heck. The only complaint I have is that the safety selector switch is slightly crooked.

I have a couple of them and they are awesome. My understanding on the selector spinning 360° is the detent in the grip.

Here I fixed it for you:

I'm having some of those same function issues with my trigger…I run 4/5 mags just fine then it just starts to hang up and only fire 1 round at a time or won't fire at all….I've reinstalled it a few times….the last time I took it out it was all green and moldy looking I cleaned it up and put it back in haven't got to try it out again hopefully I don't have anymore issues

The rough finish is because the hammer trigger and housing are cast steel, for the complex geometry on some of the part it's done that way. Only the necessary parts of the components that need to be machined are.

The Echo trigger is both a technological marvel and a piece of crap all in one. As far as I know, it is the only trigger with a solution that prevents Hammer Follow…in semi-auto. For that alone it's worth every penny. This technological advancement is both groundbreaking and huge. Again, while in semi-auto, to know that it's not possible to ever have a stoppage due to having actuated the trigger too quickly is the greatest advancement in trigger design since the rife was invented. I'd go so far as to say that if it were that the design only had this feature with no binary mode it would still be worth the price. I have future hopes that someone like Geissele or Hiperfire will get involved and transform this monstrosity into something special allowing me to mount my Echo on a plaque as a conversation piece. FosTecH is a small company pushing the envelope on weapon design. It's unfortunate for everyone that their skill in design has far outpaced their skill in manufacturing. Rest assured, if nothing else, you do own a significant piece of AR rifle history.

It appears the link to your update video is incorrect.

In the case that someone still needs help making it work with the cmmg auto sear trip, i got mine to work by dremeling off the rear tabs so it could slide free, then i had to use a spring from a clicky pen to use as the trigger lock spring, its just the right length, diameter, and is light enough to let the bolt close, however now im having bolt bounce issues and haven’t found an anti bounce weight that slides free in the receiver, the one that came from cmmg was a snug fit and would not let the bolt cycle

My spikes select fire lower has stops so that you can't rotate selector 360 degrees

Another thing that pisses me off about the Echo is after spending close to $500 on one they don't even come with Anti rotating pins where as my $130 POF trigger even does.

I bought the echo 2 trigger when it was first announced, they had a small batch available and I bought right away. I had a dedicated cmmg 22, with the arch bcg and that's a big reason I bought this trigger was to use it with that upper. I asked cmmg if I bought their auto sear trip it would work with the echo trigger, they said it should so I ordered it. It did not fire on the echo shot. I talked to cmmg again and they said they worked with fostech and to contact them, so I did. I purchased their auto sear trip. It was the same exact thing as the one I bought from cmmg, except the tab that hooks into the back of the bcg was shaved off (idk how that would possibly help) they also included a stock trigger lock spring as well as a shortened one. The note included with the trip said to try the shorter spring, if it doesn't work then to cut the longer spring down until it does work. I tried the shorter one and it didn't work properly. With the piece of the trip shaved off it allowed the sear to move freely in the upper so it would get caught and hung up on the back of the hammer, it became frustrating and I just gave up on trying to make the thing work right. Wasted nearly $100 on it.

I agree with you, the trigger should be better quality for the $500 price tag on it, I removed it from my AR I had it in and was trying to sell it but was hesitant with the current events going on, thought I should keep it instead and just installed it in my pistol last night and ordered a lighter disconnector spring to help with the heavy pull. I've thought about filing down the very bottom of the trigger shoe too, I find it to be a little uncomfortable and sharp but I'm going back and forth with that in case I want to sell. I do kind of wish I either just got another geissele trigger or just went with the franklin binary one.

Did you ever receive a response from Fostech?

I’m also quite curious about how to work with the .22 conversion as i also have an echo trigger. I haven’t found really anyone who goes over how to make it work in detail I would like to know before i shell out $300 on the kit please let me know what you find out.

You're not crazy. It does look rough. I got one before the Las Vegas incident and mine works Flawless. My only complaint is the safety is a little bit tough to select but normal wear and tear will loosen that up. You should contact customer service and notify them.

Is the safety a 3 pc ?
Maybe the center "shaft" is 180 degrees out?….
More like wrong end in 1st?

I would send it back. I haven't seen them that rough. myself I run a bfs3 because the longer trigger and work awsome on with the cmmg
