78 decibels? (I think) That's about 30 decibels less than a bolt closing. Of course for $4500 it better be quiet.

From the link.

The Aero Sonic’s un-conventional inner and outer shape and air regulating outer barrel are crucial for reducing high pressure (super sonic) waves.  The round enters the suppressor chamber at supersonic speeds, creating uneven, high air pressure waves.  These waves translate into sound.  We feel that the amount of air that is being pushed by the round is so great that if not addressed it will create a sonic boom at the open end of conventional suppressors.  This is why many suppressor manufacturers are now porting the front on the suppressor in an attempt to bleed off air.  We have effectively figured out a way to reduce the air pressure as it enters the suppressor chamber, and slow it down in a gentle way, dramatically reducing the sound and eliminating muzzle flash. The result is that we have created a true sound suppressor, muzzle flash eliminator, low signature firing system.



   Lowest Sound Suppression
       The Aero Sonic patented design slows down muzzle pressure by controlling the blast of air as it enters the suppressor chamber.  With the muzzle pressure reaching 1500 psi you cannot simply deflect it with hopes of making it quieter.  The air pressure must be controlled, and bled off, slowing it down.
        Our unique design lets the air expand in the pulse shape of a super sonic sound wave.  All internal surfaces are machined with organic curves in an effort to reduce turbulence.  Turbulence = Harmonics = Sound.  The more gently you can slow down the air, the quieter the results.
        Super Sonic air pressure is also regulated with our patented inner barrel design.  Pressure relief slots are machined in an oscillating pattern.  This regulates the outward flowing air to the suppressor chambers.  This helps the already expelled air to bleed off, and not be hyper charged as it passes thorough the suppressor chambers.
       Test fired with 5.56 ammo, sound was 78 decibels at the muzzle.
   Zero Optic Heat Signature
       By controlling the air pressure passing through the suppressor in a gentle manner, heat is drastically reduced.  This is made possible by not hyper charging the suppressor chambers with air.  Packing hot air on top of hot air unregulated creates a lot of heat.  This is why most suppressors cannot be touched after one 30 round magazine.

So 5.56 shot at 600fps?... They need better documentation.


Also as a software developer.... You really should check your CSS when you size the body text to the width of the viewing device and yet keep uncompressed images inline with text.



This was discussed once on silencer talk amusing to read thread : This is why we can't have nice things.

he's honestly just tying to sell to people that have no clue what they're buying. With as high as his mark up is, he doesn't need repeat customers. The bullshit is overflowing.

An overpriced suppressor coming from the same dumbass who tried to sell unregistered AOWs to the public. This picture was removed from his site after the lashing he got from countless people in the NFA game who know how wrong this is. He can turn metal into art work but he needs to stay out of the NFA game.

Even if it was legal that would be one of the most derpy looking AR's I have ever seen.

 

It gets a resounding meh.

Potato dildo.

And JJ is FOS.

Looks like someone's dirt bike is missing its silencer......

Maybe it still has 2 cycle oil inside for that "extra" suppression and spark arresting feature.

If you wear Affliction clothing or wear thick stitch jeans this is the suppressor for you.

A keen eye can spot the difference in the MK1 & MK2 model.
The MK2 has more "balls".


NSFW image.....my bad,

My guess is he was testing with an iPotato or something that was not an impulse sound meter. For example: http://youtu.be/JiBaQibw4QI?t=4m52s

I'd pay good money to see him grab the suppressor barehanded after doing a mag dump.

Sound like the retards used their cell phone as a meter

I just finished reading, that hole thing is bullshit, and their explanations are the exact opposite of what is true.  Plus 100 meter/s velocity increase? That is the same velocity increase from going from a 12" 5.56 AR to a 20". Again, more bullshit.

You're so distracted by the look of the thing you don't notice how it sounds. The govt will buy these things up and attach one to every politician. The price is the icing on the cake for them.

you sir have won the interwebz in my eyes for the day...in a tech forum no less

everyone slammed intacto rightfully. how about JJ's $5000 AR-15?

Cheap, really!

DELETE if illegal, but it is the most ridiculous thing I've seen in a while

That looks like an AR fucking a football.

It looks like a blimp.

Dude should of stuck to bikes and cars.

Are you sure that isn't an rpg?

Why would someone pay that much for a can when you can buy a surefire for a 1/4 of that?  In addition, surefire is a proven and extremely vetted brand.

I'm gonna laugh if he actually managed to make something that quiet and revolutionizes the suppressor industry.

I'm sure, with that Radio Shack hardware holding it together.

This. We get to laugh either way.

I saw the "100 meters per second" line and chalked it up to a typo.  It should have read 100 FEET per second increase...  

Ok, that was excusable.  The claim that a 5.56 (and we will HAVE to assume it was a full-power supersonic 5.56 round) metered less than 100 deibels is stupid.  The supersonic crack alone will meter well above that.  Am I wrong here?

This thread is hilarious

No way in hell this thing actually works well

That's nice dear; that's nice.

What next? - gonna claim your Harley clones all outperform GP bikes??

facpalm

I tend to agree.  Hell, even 300 blk subs are louder than that.

Wow!  a price tag as large as JJ head

I have an air rifle that will go super sonic with the light ammo.  It can't be 100dbls.

The insides of that POS look like a RJF game change.

Please tell me why this an AOW. This looks like a pistol to me. No VFG to require a registration right?

Because ATF hasn't issued a ruling on the Fortis as a non VFG like they did with the Magpul AFG.

So if I make an AR pistol 300blk with an 8 inch barrel I need to pepper my angus?


edit: Oh fuck. Didn't see the damn VFG right there. Stupid picture. What a fucking idiot. You figure if you were going to become a firearm manufacture you would at least not immediately commit a felony.

The VFG blended in witht the rock so I was scared when everyone said his sub 10" pistol was an AOW.

Aah yes, but his attention to dick detail is lacking as evidenced by the shadow cast by said phallic suppressor.  

       <Edited.....Image removed.........dpmmn>  

The suppressor on the end of his rifle looks like an RPG. What a joke.

He might be smarter than we realize. If he has to conduct business to keep the license so he can buy all the post samples he wants to play with. No one said you had to make good products or defend pricing, the over priced stuff keeps him from wasting time with paperwork instead of actually selling.

You might be on to something there...

Should make the videos of them being launched downrange interesting.

Bam. Now I will have to do this!!!! Wow awesome idea.

I knew I wouldn't be disappointed when I started this thread.

from a 24" bbl and subsonic ammo, with the can filled with pulling gel, measured on an iphone. From 15 yards behind the shooter.

He probably started the business so he could make himself a bunch of post-samples, and to make his hobby pay for itself since he knows some people will pay big bucks for stuff he makes.

SHOT show range day:  so how did this can sound to everyone in person?

Oh wait - nevermind.  He did not show up for that:


https://www.shotshowrangeday.com/exibitors/exhibitor-list

I'm sure we're all very surprised he didn't show up. Probably didn't want to make all the other suppressor manufacturers jealous with his game changer

His explanation sounds just like that of the Turbo Encabulator;
