Having some fun with the prototype, 25 rounds of .22LR at a steel torso target.

I have assigned my patents to Fostech, they are releasing this as the ECHO trigger

  1. Can I ask you a question? As you can see I bought your invention. 😀 For some reason when I run mine it loads a round into the barrel on occasion and quits working. I have to drop the mag in order to get it to fire. I don't think I am out running the bolt. Did you have to use the anti tilt weight from CMMG to get it to work properly?
