The Quiet Shotgun™ - Carbon fiber, low cost, no permit, shotgun "silencer"
Maybe I can help you to get started.
The possibility of a patent for the Quiet Shotgun has long since passed since my first crude designs that took up the entire length of my '78 Volare station wagon. I have other inventions (and patents) plus a 53-year career in high-end audio which takes up much of my time. My goals for the Quiet Shotgun are limited to public awareness and proving the efficacy of this technology.
I am starting small with a pilot program in Minnesota. There is a lot to learn to fully exploit the technology of the Quiet Shotgun for hunting and shooting. I will supply a Quiet Shotgun barrel(s) and a complete support package to ensure success for those in the pilot program. For those that can not be included in this pilot program, check "News" for additional information.
