I designed and printed a suppressor (based loosely on k-baffles) for my air rifle.
It consists of 3 sections - a barrel section that just pushes tightly onto the end of the barrel, an end cap (I've provided 2 different end caps designs), and the k-baffle section - which you print multiple copies of, the more you add the quieter the result.
The sections all push together then can be glued in place. Because each section is small you can make quite a long suppressor regardless of the print volume of your printer.

love it its helping me do a mod on a gun

what type of mount use?, 1/2 x 20 UNF male thread?

Nope it's just press fit.

Please could you help me out. I love your design but i need the part that fits onto the barrel to be 10 mm on the inside. Your current model is 15 if i am not mistaken. Any help would be appreciated

Nice piece of creative thinking. Question ...
How do you attach this to let's say airrifle barrel

You would slip it onto the barrel and use a grub screw if i am not mistaken.

I've made an 8 baffle version of this (9 if you count the endcap) modified to fit my grandson's RatCatcher. I printed a shroud for it just to tidy things up. This mod is whisper quiet. Well done on a great design and thank you.

Read up on federal firearms laws. It is likely a felony to produce this

Only if you live in the USA.

Hello, nice design work, could you possibly E mail me a PDF of this ??? Mark

ill take a shot at it :D keep you updated boss. Thanks for the great design work :)

This is a great design.
I imported the K-baffles into SketchUp, copied it so I had 8 segments, then made them into one component / printed as 1-piece - prints perfectly and much easier than sanding and fitting them together after printing.
I also modified the "barrel adapter" to fit my Crossman 2100 Classic BB-gun; It goes around the front sight and is held on using a hose clamp.
I am also in the process of designing / modifying the "barrel adapter" to fit a friends Diana Break-Barrel pellet gun.
Awesome job with this simonx........ Thanks

Just so some people know, using this on a real firearm is illegal and controlled by the BATF. Suppressors or sound-modifiers are totally legal in most places on air rifles/BB guns/airsoft/etc.

Try to remember that this is the internet, not the USA. Other countries are different, using it on a real firearm might be illegal where you come from, and where I'm from people with mental illness aren't allowed to own firearms, especially not semiautomatic military rifles.

In Germany we have the "Waffengesetz" (weapon law), and you have to look up this subject carefully, to find out, that it's not that easy.
In "Anhang 1 - Begriffsbestimmungen (appendix 1 - terminology) You find the following definition in 1.3:

"Wesentliche Teile von Schusswaffen und Schalldämpfer stehen, soweit in diesem Gesetz nichts anderes bestimmt ist, den Schusswaffen gleich, für die sie bestimmt sind. Dies gilt auch dann, wenn sie mit anderen Gegenständen verbunden sind und die Gebrauchsfähigkeit als Waffenteil nicht beeinträchtigt ist oder mit allgemein gebräuchlichen Werkzeugen wiederhergestellt werden kann"

(Relevant parts of shooting-weapons* and baffles are legally treated the same way as the weapons they are made for, if no other law says something else. This applies also to those, that are connected to other items and whose usage property is not affected or can be restored with usual tools.)

*I chose the literal translation "shooting-weapons", because according to 1.1 in the same appendix the word "Schusswaffen" describes not just firearms but also air-rifles:

"Schusswaffen sind Gegenstände, die zum Angriff oder zur Verteidigung, zur Signalgebung, zur Jagd, zur Distanzinjektion, zur Markierung, zum Sport oder zum Spiel bestimmt sind und bei denen Geschosse durch einen Lauf getrieben werden."

(Shooting-weapons are items, that are designed for attack or defense, for signalling, for hunting, for distant injection, for marking, for sport or play, and that drive a projectile through a barrel.)

Then there is § 26: "Nichtgewerbsmäßige Waffenherstellung" (non-commercial fabrication of weapons)

"(1) Die Erlaubnis zur nichtgewerbsmäßigen Herstellung, Bearbeitung oder Instandsetzung von Schusswaffen wird durch einen Erlaubnisschein erteilt. Sie schließt den Erwerb von zu diesen Tätigkeiten benötigten wesentlichen Teilen von Schusswaffen sowie den Besitz dieser Gegenstände ein."

(The licence to non-commercially make, work on or repair shooting-weapons is granted by a permit. It includes the right to buy and own the required parts.)

This altogether means, that you need an (expensive) permission, to legally print a silencer for an air-rifle.

So at least in Germany you should not make this. In other counties you should read the laws carefully, before you start.
I destroyed mine, after I read this.

Hi Simonx - Could you please send me a set of drawings - pdf. Thank you very much for this design

Hi Simonx - I just purchased a Ruger Blackhawk .177 and found that it is much louder than expected, so I am going to try your suppressor. Can you also send me a pdf format to [email protected]? Also, do you have a base parts list?

Hi Simonx,can you please send me this file of the silencer blue print in pdf form to [email protected]

Has anyone tried it out? Just wondering how effective it is.

I have it on a Ruger Blackhawk .177 air rifle (1000 fps) and it does a pretty good job of muffling the sound. I use 6 baffle sections - the more you add the quieter it gets. You should ensure when glueing it together that the through holes in the baffles don't line up.

is it for .117's or .22's?

The centre hole is large enough for both calibres. It's a simple task to increase the opening further as each element is a profile sketch that's been rotated through 360 degrees to for the part.

Shouldn't this be removed like all the other gun stuff from thingiverse?

simonx - in reply to

Why is all the other gun stuff being removed from Thingiverse? Is it a knee jerk reaction to what happened in the USA recently? Not all countries in the world have such stupid gun laws ( or the lack of ). What's next, banning religious items? Hey let's ban anything Christmas related as it's bound to offend someone.

This is a website for people who make and design stuff - from all around the world, not just one country!

Yea, America pretty much sucks, at least from my perspective. I think Capitalism has had its day. Maybe its just the east coast, who knows? I think it started going to crap after 911, and that whole "never forget" campaign, and the militaristic attitude of the populace. USA doesnt even have a strong Constitution anymore, we just want to maintain our lifestyle while using the majority of world resources, and if that means killing people around the world, that what we do. Well, A bunch of shitty things have been done to me by Americans, and I am not forgetting either. Anyway Netherlands must be cool. I wish I could live in Canada or something, but I am stuck in New Jersey for now. Wish me luck!

Sorry didn't want you to get the wrong idea, I have nothing against you uploading it, I was just wondering :)

simonx - in reply to

No worries Jeppe, my comment was aimed (pun intended ;) more at the site administrators in case they do decide to remove it.

I've looked through the site policy statements and didn't see anything relating to gun related models - although there is a distinct lack of them on Thingiverse.

Have a good New Year!

I've looked here:
And in 3.3 a) ii it says:
"... or contributes to the creation of weapons..."

What is the barrel opening diameter? Is there a source file?

The barrel opening is 15.5mm - I modelled it in SolidWorks so I can export files for you, what format? 

I have inventor and freecad so maybe .step will work. I also need to modify the barrel end to have an opening for a sight. My son has a Gammo. 

I've uploaded a step file for the barrel section. It's very simple - it's just a rotated profile so it's easy to modify.
