Your problem could be The double wire that sticks out of the handle and hugs the cylinder. It works fine when its out, but when you put it in the upper receiver, it puts tension on that wire, which causes the contacts to not connect properly.
Just as a note, when you pull really hard, the trigger is not moving. Instead, it's pulling the gearbox farther back in the grip, which pushes the previously mentioned wire forward a little more.
