A cool half million for a paper drawing. Here’s the description:
I invented this silencer when I was a top physics student in a top engineering school 30 years ago. This design can achieve 22 long rifle ammo sound intensity of 97 db with a 6″ barrel. (Intensity; the lower the better). Till today; even 113 db will cause some manufacturer claiming “Top dog of the hill”. They don’t even believe 107db is possible. Not to mention 97 or 99 db. It is beyond imagination. The size of the can is only 1.2″ x6.6″. The ammo is a 1070f/s standard 40 grain or green tag Minimag by CCI. This involved 3 or 4 principles never been used in silencer technology. This design will make all the silencer designs and products in the world obsolete immediately. I never contact or explose this design to anyone besides myself in the last 30 years. I am only one knows its existence. The automobile and military will be very interested in its existence since silencer uses to be very troublesome and expensive. This is very cheap and good in term of performance and price. I did not even try to improve this design. It may get better if you optimize it components like changing the dimensions of the parts after a series or serious testing, or using steel instead of aluminium. The manufacturing cost is only 1/4 of the regular silencers. In some case, only about 1/10 of others because it is so light it may not need buffler to connected to a Browning design. The buffler connector alone usually cost $50. Once you receive the design paper, you should have your patent lawyer ready and wait no time. The patent will make huge profit for a long time. The world manufactures did not invent this in last 100 years. They wont outsmart me in next 100 years.
Auction unsurprisingly with zero bids, over at GunBroker.
haha I don’t know *side eye*, if his design is as good as he says it is how come he sat on it for 30 years and why is he selling it? I’m sure he has a variety of excuses every time someone asks him that.
The best part of the whole description is “The world manufactures did not invent this in last 100 years. They wont outsmart me in next 100 years.”. Is he planning on getting 0.5 Million or taking this thing to the grave? Once one of these “revolutionary” silencers see the light of day, it will take the other silencer companies no time at all to reverse engineer it and make small tweaks to avoid patent infringement.
Thoughts?
