I am not 100% sure this is where I should be posting this, but as I would really like to one day make my own version I'll post it. Ran across this link in Shotgun News [URL] http://www.steinkamp-arms.com/ [/URL] The YouTube video kind of sucked I thought, and makes me wonder how many people are going to get smacked in the face with empties. If I can ever find out how the inner works go I'd be very interested in making one of my own.
