Air rifle silencer

Air rifle silencer by simonx Dec 3, 2012

Description

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.

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

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?
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 :)
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!
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.
