FYI for those of you thinking about buying the $269 Fostech echo sport trigger for the 15-22.

If you install as shown in the instructions it will not work because the 15-22 upper (or more specifically the bolt I guess) doesn’t push the trigger lock forward. It won’t fire unless the trigger lock is forward.

However if u simply remove the trigger lock spring it works like a charm because the trigger lock is forward (the spring is what pushes the trigger lock backward). I’ve done quite a few tests of semi auto, 2 shot, and mag dumps with the 35 round plinker magazines and no hang ups. Ironically I have had some hangups with the stock magazine it came with.

The rounds per minute is crazy high, as in around 500-600 rounds per minute (not counting mag changes of course).

The two shot action is excellent. It pretty well fires two shots in echo mode as fast as you can fire one shot in semi auto mode.

I need to test it more and do tons of mag dumps but so far this trigger without the spring is an absolute blast. I’ll update this later as I learn more/do more testing with it.

Updating this thread with info. from another user out of the area who contacted me.

He says that the rear trigger lock is a safety feature and it's only function is to not allow the trigger to outrun the bolt. He also says that The echo ar2 has the same piece but the ar1 did not.

He removed the spring as mentioned above and his is working fine after that. Cheers!

Where do I get the trigger? I was on their waiting list for six months, only to have them tell me they cannot ship to Oregon. :confused:

Darn that would be frustrating. I think most of the 3rd party vendors got them in stock in March or so. I bought from “Tactical Sh!t” but I’ve seen the same prices of $269-$289 at other vendors as well.

$269 was sale price but I’ve seen them at $269 regular price at other vendors so maybe after you find one at a vendor double check “retailmenot” or look around the vendors site for an extra 10% off or whatever and u may be able to get for less than $250. The vendor I mentioned will ship to OR as I’m sure several of the others do also.

Updating this thread. I removed the trigger lock completely because it seemed silly to leave it in there after removing the spring. Works great!

Much cleaner this way cuz trigger lock is just sort of flopping around with no spring and it serves no function. If one were to move the trigger to a regular AR u could put the trigger lock and spring back in for that gun. But for 15-22 the trigger lock serves no function (and if trigger lock is installed with spring in a 15-22 the trigger won’t work).
