Does a full-auto or semi bcg come with the trigger?
I am thinking about putting one in a LMT 12 inch piston upper. How easy is it to mill the bcg to make it work or will Fostech mill one out for me if I sent the bcg to them? |

It's pretty close to an M16 carrier. Takes about 15 minutes with a file to make an M16 carrier work with the echo. My cut carrier is on the bottom. The echo carrier is on top.https://www.AR15.Com/media/mediaFiles/57761/20170119-214738-129674.jpg Quote HistoryQuoted:

All it take to make it work is to remove enough metal so the upper can close and the bcg is pushing that sear so the trigger would fire the second shot on echo mode? |

Yes. You need to remove enough material such that the carrier can fully close and doesn't just get stopped by the trigger block.
A light cut has the added benefit of more fully compressing the trigger block which lowers the required pressure to activate the echo shot. |

Green toggle springs seemed to just effect the first shots pull weight and didn't change the extra pull to set the echo shot off. I mainly put them in because I wanted a harder strike and I'm hoping they will have enough extra strength to shoot the 6,000rds of cheap ammo I bought  To set off the echo shot it takes 6lb of pressure when using my cut carrier and about 10lb with the provided carrier. I think it's a bit shorter to activate with my cut carrier as well, but I haven't come up with a good way to measure it yet.So I bought the green hyperfire spring kit as well after you posted the above. Once installed the pull weights with the green springs installed seem way lighter than with the stock echo springs. The green springs are noticeably stronger than the stock echo hyperfire springs on the bench; seems like a no brainer to use them, stronger hit and lighter trigger. Weird stuff but my trigger is now friggin awesome. BTW shipping you a bushing with the correct id this time. Just made a few more. |

I won't ever sell these. I have been using some old 22cal rangemaxx bore brushes that I cut down and drill out to make them. Takes away the sharp 90* turn that the post has to take at the end of travel in echo mode. The bushing makes the post move "back" at the end of travel instead of "up and back". Nice smooth echo activation.

If that is all the material needed to be removed it would be nice if Fostech would have an option to get the trigger without their carrier for a lower price. Maybe that is in the works once the initial orders are filled?

I got my Echo trigger on Tuesday, installed it on Wednesday and fired it for the first time today. Works as advertised, slicker that cat shit on a linoleum floor!
 My only beef is the it does not play well with JP silent capture spring units. I have 9mm and 5.56mm uppers for my SBR and have a capture spring unit for each upper, however once the Echo trigger is installed the only way to change out the capture spring is to remove the buffer tube!  I'm thinking that I might be able to mill or grind a flat on the leading edge of the front piece, I should be able to work it over the trigger lock in the forward position.

ok now going to order a set of kns gen 2 mod 2's go to the hardware store and get some flat head cap screws that fit so they are easily serviceable in the foeld w/o 2 allen keys to fix the pin walking some of you have experienced but my question now is should i go with the .1555 pins to tighten this setup up will they fit and does someone have a mic or set of the oversized ones they can or have tried

I finally got Dubtap's bushing installed. It dropped the echo activation weight to 6lb with the included echo carrier and 5.5lb with my newly cut carrier. Seems to work really well, now I need some range time. Great ingenuity @dubtap
Here is the carrier I cut today. I will be sending this one to mbell for him to review against the BFS III.

Bushing specs.
ID .109 inch OD .190 inch Width .117 inch I would not make the OD any larger. I tried and it made the trigger unsafe. With this size bushing it looks like you still get full engagement of all sear surfaces. As I said before I have just been using cheap rangemaxx 22 bore brushes. If you cut around the aluminum of the crimp you can then unscrew the wire bore brush out of the base and there is a nice hole left to align for drilling and then just a little file work to get the width correct. I have been using the back end of the drill bit to hold the bushing while filling down to size. |

I have the other type springs from my Hiperfire trigger and I might try them on the fostech echo. |

I tried .250" OD bushing and it cause the trigger to hammer follow and not to be caught fully on the sear surface on the end of the hammer. Never shot it that way. I still wanted it to work as designed just be smoother and lighter. Hopefully fostech will *tune up* the echo over time.
Green springs made it a little lighter pull. And of course use a slighly trimmed full auto carrier to keep the trigger saftey fully closed. |

I finally had a chance to put the extra power recoil spring in my 22 upper and test it with dry firing. If the "extra power" spring is any stronger than the stock one, I couldn't tell it. Cycling it feels the same, and it is still not powerful enough to overcome the stock sear spring. I did not test it with the reduced power sear springs since I know my stock setup will already cycle with those. I also purchased the enhanced firing pin. I'm not sure when I'll be able to live fire test.

I saw the picture of the light weight bolt carrier that was altered to activate the trigger lock. Has anyone used the lighter bolt carrier and carrier spring combination to speed up the cycling of the action and try to improve on the 650 RPM cyclic rate?
I'm thinking that (for those with super fast trigger fingers) this should allow a faster cyclic rate?? |

May or may not work if this is your issue. Shoot me an IM and I will send you a few, you will have to trim their length to size though. Over the next few months I was planning on picking up a 22 conversion kit. Hopefully you have it figured out before then.

Did the bolt mod and although I am happy to have my bolt carrier working with this trigger system it didn't make a positive change to the trigger pull weight. It seems to have taking away most of the take-up to engage the release shot but it may have also made the release shot stiffer to engage.

Interesting. I guess you don't have a gauge to check before and after weight. I'm thinking your echo carrier was already pushing the trigger lock all the way forward.
I wonder how a small bushing like dubtap makes would affect it. |

I think you may have filed a little too much off your carrier. If you do this you end up with an echo mode that will stack up in pull weight right at the end of the trigger travel. In echo, the trigger pulls the trigger lock fully against the trigger housing right before it activates the echo release shot. The extra pull weight your feeling is the heavy ass trigger lock spring u are fighting against. A correctly trimmed carrier will hold the trigger lock completely against the trigger housing when your bcg is fully in battery but not hold the bcg out of battery. Thus you will never feel the extra pull weight because the bcg is compressing the spring fully for you. |
