Next Generation Wet-Fire suppressor
Bio-Tech Internals


I am constantly researching, experimenting and refining my custom suppressors - both design and material. Combining my other hobby of microscopy, I have developed what I consider to be the best material for both Rim-fire and PCP suppression - with up to 90% noise suppression.
These Bio-Tech internal suppression kits will be available within sealed unit and full take apart suppressors - both being able to be dry or wet fired.
These photos show the other parts that will make up these suppressors.
Although already copyrighted, I will not be displaying photos of this latest breakthrough.
Parker Hale are arguably considered the best and quietest suppressors in the world.
Having only recently acquired a PH suppressor, I decided to put it to the test against my latest Wet-Fire suppressor. What makes my latest suppressor unique - is not that it is take-apart, not the reverse venturi ports (although they are my own unique design), it's not even the ability to shoot wet that is special. What sets this unit apart from every other suppressor on the market - is the special absorption material it is hand crafted from.
Which one will be better - my latest project - or the world famous Parker Hale?
Watch the video - and you be the judge.

Stats: Body weight 130 grams dry. End cap weight 58 grams. Internal suppression ports a total of 30 grams.
Total suppressor weight 218 grams - the weight of a large apple!
I have turned the internals from my own unique design and have not copied - or even view - any other venturi units.
However, what makes this suppressor so advanced and efficient is the material that the internal spacers and ports are made from - especially being able to wet-fire this kit.
A few years ago I displayed my full designs and methods on the internet. I won't make that mistake again - as within six months - three other engineers in NZ were making and selling identical units as mine.
