Echo II trigger with dedicated .22lr upper

Anyone on here done this?

Here is a video on it:



I just ordered an Echo II finally, as I found the lowest price I've ever seen yesterday. Thinking of dedicating the Echo lower to a .22lr upper. Which upper has the M16 style BCG that works with the Echo II?

A few years ago I had a S&W MP-22 with a Slide-Fire and Bushnell TRS, but it got stolen after I built it but before I could try it out. I really like this idea of high-volume .22 for fun.

I installed a Fostech trigger in an AR-15 in .300 B/O which is really fun and just installed one in an AR-45 .45acp but haven’t made it to the range yet, should be fun.
I think in a .22 lr upper it would be a blast.
This AR-45 should be awesome with the Echo trigger.

I have no experience with the Fostech Echo II, but the CMMG drop in 22 adaptor works perfectly with the Franklin Armory Binary Trigger. I suggest you look into the CMMG 22 adaptor, or an upper that uses it.
