I've been working on a mod that has already been done by others(punisher's customs) but I'm doing it in my own way.
It's basically a cylinder in the grip to move the sear and a micro 3-way behind the trigger to activate it. It's all powered off a mini-rock reg mounted in the front of the vertical adapter.hopefully it will work well, and give it a really light trigger pull. If I ever get my act together, I'll try to post some pics somewhere.
