Suppressor for AK, used by Spetsnaz.

[Mishka]

Suppressor was created on request from certain Russian Spetsnaz operators. They wanted an effective sound and flash suppression for use with standard issue (supersonic) ammunition. Tje main goal was to develop a lightweigh and inexpensive device; it was achieved by using aluminum alloys, lathe turning and CNC machining. Shown here is a prototype.

Thank you for showing.

Maximizing 'Fractal' surface increase with minimal
machining contortions.

Is this your design and manufacture?

Thought comes to mind. Were one to slice each section into
a crenelated baffle and then rotate them 90º to increase
turbulence, would there be a measurable sound reduction.

Reminiscent of Stetchkin's straight forward effective suppressor for
Автоматический Пистолет Стечкина.

[Mishka]

It developed the device recently, where a month ago. He showed a good reduction of sound and flash. The measured noise level is not yet made. The upstream developer and manufacturer of me. Who is going to do an enhanced version, based on the results obtained. Thank you for suggesting the idea.

In the utube it shows that all 4 sides are bored the same. So 90* already. Maybe 45* would yield added results?

Any theories on why this design is favorable over the GemTech G-series, slanted AAC, or Liberty cores?

Thanks Mishka. Beautiful photos to show details.

Again WR is correct!

My cursory view saw just the y-axis drill holes making
the slabs like Ruffles potato chips:

Like potato chips ( when hopefully the Hearing-Protection-Act passes the $200.00
savings will allow many purchases ) you can not stop buying just one the top line of cans.

Cans are in the same logical class as magazines.

Those baffles are neat. They remind me of sound dampening foam used in recording studios to reduce reverb. I'm sure the principle is similar here; deflection of sound.

Metal implementation of anechoic wedge foam:

e.g. << https://acousticalsolutions.com/product ... dge-foams/ >>

Extrapolating from copper folded fins in electronics another example of increasing surface area in
finite volume ... such as wrapping a section around a rod say for example .25" in diameter.
Not too much of a chore.

If you're interested, I will show you more of my work and share ideas.

Yes please. But "SilencerSmithing" is the correct subForum for designs.

Others can correct me if they disagree.

Thank you, I'm new to the forum, and it is not know much English.

добро пожаловать!

That core looks a lot like something in my sketchbook, although I was planning for use in a .22 can. I'd love to know how it sounds.

[whiterussian1974]

AAC's slanted baffles patented by Robert Silvers (Site Admin) are probably better at suppression. Spetsnaz use is for rapid and auto fire. So dwell time is limited by followup shots. Need to lower pressure. They would probably benefit from his design though. Maybe they chose transverse boring for ease of Mnfr?

Mishka said that he had other designs to share. I hope that he returns. He seems like a really great guy. (Of course, I'm a heavily biased observer. )

To implement the ideas need time in a month will be an improved version.

[whiterussian1974]

You could post the design drawings now. Many of us do that to get feedback from others before we actually build the suppressor.

Have you read the Links to Completed Builds thread yet? Lots of neat ideas and innovative applications.

Here's one that was made by bending flat metal plates. Simple design and works well. Not as quiet as other designs though.

Hi Mishka,

you live in Russia, I live in France.

I wait for your improved build with great interest, do you think it would work OK for my 30-06 Springfield rifle? I have the short barrel version..Very nice and light but very loud!....It is already threaded for a silencer but it is difficult to know which one will work, and after seeing your posts I was thinking of making my own like yours.
Another forum member has helped me regarding cartridge so I will be using full power factory load, OK the supersonic down range crack will still be there but that is not my worry, if I remove the flash suppressor I have the noise at the gun is reduced but the kick is like a donkey! With the suppressor the kick is not there but the noise is! So I want to remove the kick and the noise from the firing point.
Do you sell your silencers? Would I be able to buy from Russia? I cannot buy from USA (they will not export) and I am reluctant to pay a lot in France or Switzerland without knowing if it will work for me.

I still can not sell silencers to another country.

interesting shop. and you'll also notice the OD is not a cylinder , looks like there are chambers between each section on the OD for gases to expand into.

[1rflman]

a crenelated baffle and then rotate them 90º to increase

Not cylinders?

[a_canadian]

Who knows what the kid is talking about. He's got an arrow pointing at toilet paper. Probably some clever private joke?

I see nothing non cylindrical in any of the areas pointed out.I imagine that's a disposable shop towel but the resemblance to industrial toilet paper is uncanny.
