This is likely illegal here in the US, but oh well, I love it.

Likely not. It would not be hard to get a determination letter, although they may want to have a physical item mailed in to ensure that it cannot be modified for use on a firearm (as defined in the NFA).

Without mailing anything in I have a determination letter stating I can make a monocore out of machineable wax because wax is deemed too soft to be even remotely effective at suppressing a firearm.

With that said most paintball and airsoft suppressors are not classified under the NFA but a couple failed the ATF testing and would reduce the sound, even though only a tiny amount, on a real firearm.

The Americans are very funny, you can have all the weapon you want, but you can't put a silencer on it because it's dangerous. Very funny.

No one in the U.S. that understands what a suppressor does or even has the slightest knowledge of what a suppressor is, supports the ban against them. It's the fact that they seem scary due to how they are portrayed in movies etc. People tend to fear what they know nothing about, I suppose.

Yeah my sentiments exactly :)

This is made of plastic. Actual "silencers" are made of metal. This isn't even something that requires research to know -_-

Yes it is made of plastic. The material that it is made from is not a criteria of the law. An ATF determination letter would be the only safe way to go about doing it in the US (as well as a check of state and local laws).

Here is a plastic one that counts (save for a metal threaded knob to attach it, the baffles and can are ABS 3D printed).

Maybe some research is required in the US to know.

Are Paintball and/or Airgun Sound Suppressers NFA firearms?
The terms “firearm silencer” and “firearm muffler” mean any device for silencing, muffling, or diminishing the report of a portable firearm, including any combination of parts, designed or redesigned, and intended for use in assembling or fabricating a firearm silencer or firearm muffler, and any part intended only for use in such assembly or fabrication.

Numerous paintball and airgun silencers tested by ATF’s Firearms Technology Branch have been determined to be, by nature of their design and function, firearm silencers. Because silencers are NFA weapons, an individual wishing to manufacture or transfer such a silencer must receive prior approval from ATF and pay the required tax.

LOL it's still illegal here :(

suppressors for airguns must be permanently attached that's the law if it isn't permanent then it could be installed on a firearm any device the suppresses the sound of a firearm by even 1 decibel for one shot is considered a suppressor under NFA and BATF rules. a bottle is a bottle until its installed on a firearm. I build firearms and suppressors legally this device is absolutely illegal to produce and install it cant be permanently installed to an airgun, under ATF rules it would need to be pinned and welded or welded to the muzzle so that any attempt to remove it would damage the muzzle since its plastic this is a problem.

Its not illegal for an air rifle or pistol. I cant I cant speak of my sources & how i know but now if you installed this on a real firearm without class 3 licenses then yes you could in theory be breaking federal & or state laws. You can buy tubes made for real guns its the baffle is whats regulated in a supresser , silencer ect.

That's not how laws work. "I can't speak of my sources or how I know" then it's not legal. Silencers fall under the NFA and require a license to own. What epicdoom has said correlates with the established ATF guidelines (https://www.atf.gov/firearms/qa/are-paintball-andor-airgun-sound-suppressers-nfa-firearms):

            "Numerous paintball and airgun silencers tested by ATF’s Firearms Technology Branch have been determined to be, by nature of their design and function, firearm silencers. Because silencers are NFA weapons, an individual wishing to manufacture or transfer such a silencer must receive prior approval from ATF and pay the required tax."

Unless you have some verifiable source for your claim, you are spreading misinformation that could land people in jail for decades+. Hell, I would even be cautious permanently fixing them to the airsoft/paintball gun as epic doom claims because I haven't personally seen the writing where they say that makes it OK. Silencers are heavily regulated and when dealing with the ATF excessive care is needed as there are VERY severe consequences for even unknowingly crossing the line. EVERYTHING should be in writing by a federal body/agent as being explicitly allowed.

Unless you live in Kansas. Make the suppressor in Kansas and STAMP made in Kansas on it. Can't be sold or taken past the state border. It's been a few years since the law was passed and I don't make suppressors but you can look it up and correct any information that I've listed falsely.

You may want to revisit the whole "if its made in the same state" thing. See this case for reference http://www.mtssa.org/?p=76

Article I Section 9 Clause 5
"No tax or duty shall be laid on articles exported from any state"
except when it does

Probably a felony to produce this.

Not to produce, only against the law to use on a gun. Probably one of the most pointless laws in existence, I honestly cannot believe that it hasn't been overturned yet. It was only ever made due to the public's fear of how they worked when shown in movies, as if they can make a gun almost completely silent, when in reality, it turns something that surely causes hearing damage into something that has the sound rating of a firework.

That is particularly bad advice. Possession of anything determined to be a suppressor is a violation of the national firearms act, unless you have a tax stamp. Manufacture is similarly illegal unless you have a tax stamp. You may not transfer without, um well a tax stamp. Title 26 is tax code not criminal acts so really this law all falls under tax law despite Article 1 Section 9 Clause 5 "No tax or duty shall be laid on articles exported from any state" but the courts said "meh we like this law" and so it is binding.

BTW the NFA was passed as a "mob tax" and had nothing to do with the public's fear but rather a revenue bill during the great depression.

Airsoft and paintball suppressors do count if the ATF says they do. A determination letter is key to whether or not a particular device counts. https://www.atf.gov/firearms/qa/are-paintball-andor-airgun-sound-suppressers-nfa-firearms

26 USC 5861 (part of the National Firearms Act of 1934 as amended)
It shall be unlawful for any person—
(a)to engage in business as a manufacturer or importer of, or dealer in, firearms without having paid the special (occupational) tax required by section 5801 for his business or having registered as required by section 5802; or
(b)to receive or possess a firearm transferred to him in violation of the provisions of this chapter; or
(c)to receive or possess a firearm made in violation of the provisions of this chapter; or
(d)to receive or possess a firearm which is not registered to him in the National Firearms Registration and Transfer Record; or
(e)to transfer a firearm in violation of the provisions of this chapter; or
(f)to make a firearm in violation of the provisions of this chapter; or
(g)to obliterate, remove, change, or alter the serial number or other identification of a firearm required by this chapter; or
(h)to receive or possess a firearm having the serial number or other identification required by this chapter obliterated, removed, changed, or altered; or
(i)to receive or possess a firearm which is not identified by a serial number as required by this chapter; or
(j)to transport, deliver, or receive any firearm in interstate commerce which has not been registered as required by this chapter; or
(k)to receive or possess a firearm which has been imported or brought into the United States in violation of section 5844; or
(l)to make, or cause the making of, a false entry on any application, return, or record required by this chapter, knowing such entry to be false.

26 USC 5845 defines things. Firearm is defined there (and its not the normal definition but it is what matters)
For the purpose of this chapter—
(a)Firearm
The term “firearm” means (1) a shotgun having a barrel or barrels of less than 18 inches in length; (2) a weapon made from a shotgun if such weapon as modified has an overall length of less than 26 inches or a barrel or barrels of less than 18 inches in length; (3) a rifle having a barrel or barrels of less than 16 inches in length; (4) a weapon made from a rifle if such weapon as modified has an overall length of less than 26 inches or a barrel or barrels of less than 16 inches in length; (5) any other weapon, as defined in subsection (e); (6) a machinegun; (7) any silencer (as defined in section 921 of title 18, United States Code); and (8) a destructive device. The term “firearm” shall not include an antique firearm or any device (other than a machinegun or destructive device) which, although designed as a weapon, the Secretary finds by reason of the date of its manufacture, value, design, and other characteristics is primarily a collector’s item and is not likely to be used as a weapon.

hello , congratulations for the work face
tell me , what is the measure of the thread q fits . the gun barrel ?
serves in the Hatsan Airgun , PCP Galatian III ?

It is illegal to silence or muffle an airgun in the united states without a legal silencer. it does not need to be a firearm. It's also illegal to print this device if it will fit on a real gun, unless you have already filed your paperwork and gotten the tax stamp to do so. 10 years is a long time.

Comments deleted.

That is completely false. A suppressor in definition of the ATF is a muzzle device used for the purpose of reducing the audible (decibel) sound of a FIREARM when fired. Would airsoft suppressors be the same? No, because they are not firearms< and neither are pellet guns.

Link to ATF website explicitly calling paintball/airsoft silencers illegal. If it can dampen the noise, it's illegal. https://www.atf.gov/firearms/qa/are-paintball-andor-airgun-sound-suppressers-nfa-firearms

"Numerous paintball and airgun silencers tested by ATF’s Firearms Technology Branch have been determined to be, by nature of their design and function, firearm silencers. Because silencers are NFA weapons, an individual wishing to manufacture or transfer such a silencer must receive prior approval from ATF and pay the required tax."

Not exactly.

Air guns are NOT considered firearms and silencers under NFA laws are things that can muffle or silence a "firearm" by definition.

However if you can mount the "airgun suppressor" to a firearm and quiet the shot in any way it could be construed as a firearm silencer.

There have been cases in the past were people have made airgun suppressors that were detachable and later when the ATF tried testing their "airgun suppressor" on a .22LR rifle and if it worked even a little bit that airgun suppressor was then considered a firearm capable suppressor and thus illegal. Or at least something that was supposed to have been regulated and transferred via the NFA process. And that person then gets the Federal prison shaft.

Lots of companies are making permanently attached airgun silencers that are basically integrally suppressed airgun barrels. Since these permanently attached devices cannot be used in anyway on a firearm than they are are legal.

As long as the airgun parts (silencer) can not be in any way shape or form used (even if for only one shot before it breaks) on a firearm then the NFA laws and ATF have no purview over it. But as soon as it has the possibility of being used on a firearm it does.

You can pretend it's all good but that little bubble of reality doesn't extend beyond your imagination unfortunately.

you can make a silencer out of a bottle, doesn't mean there illegal.

Actually it does mean they are illegal. Even a baby bottle nipple becomes an illegal silencer if you slip it over the barrel of a gun. What you have CONSTRUCTIVE INTENT. Making this, is constructive intent regardless of what you "THINK" you intend to install it on. It's not up to YOU what the investigator determines your intent is, that is up to him/her.

If you do not own any firearms, and you are just a kid, yeah you probably will not get into trouble playing with this.

Do you own a .22 rifle? A pellet gun? In that case this is constructive intent.

Yes, plastic bottles are illegal if you slide it over the barrel of a gun.

Don't blame me I didn't make the law, I'm just trying to save you from 10 MANDATORY years in federal prison.

Does this silencer actually work? Has anyone actually attached it to an air rifle or anything of the sorts?

Just printed one and fitted it to my smk xs501 .22 co2 rifle. It has made a big difference to the sound, reducing the crack to a soft puff.
Having read many of the comments from the USA I'm so glad I live in England.

In our defense: No one here supports suppressor bans.

Yeah, I designed it initially for my Crosman 2250 "Ratcatcher" CO2 carbine, and it made a heck of a difference. Now the Australian magpies we have here have wised up and I only get one shot anyway.

hey vik, maybe you can recylcle my design to improve your muffler, it's quite similar: http://www.thingiverse.com/thing:220574http://www.thingiverse.com/thi... you can also increase the number of stages inside the script.

Tesla inspired One Way Valve

A friend printed this to try on a .22 caliber pest gun. He didn't notice any change in sound whatsoever but he and I have yet to try as intended.

you need to buy subsonic ammo for it to work. .22 rounds travel faster than the speed of sound, so you will still hear the "sonic boom"

Probably because his BB gun is firing a supersonic projectile, and an airgun is not.

There are suppressed pellet rifles available for sale in the U.S. A key attribute is permanent attachment to the barrel such that it cannot be transferred to something else.

Interesting that there are almost 100 downloads and no one has clicked the "I Made One" button O:-)

most people never print it, and when they do are usually too lazy to upload an I made one photo.

I'll add to the caution: Fair warning that this should not be modified for any other purpose. I dont know about airguns, but if someone were to afix this to the end of a firearm, A) you're an idiot and B) you'll face a $25k fine and 10 years in prison (technically for a tax evasion). Even if its just for "fun". BATFE doesnt really joke about this kinda thing. And people WILL report you. Most people are kinda weird about these things.

But I say well done! I like it and although I dont have an airpistol, I might just print one for moral support! I've played with some designs, but never printed. Maybe this will be a little motivation! Cheers!

Q: Are Paintball and/or Airgun Sound Suppressers NFA firearms?

The terms
“firearm silencerâ€Â&#157; and “firearm mufflerâ€Â&#157; mean any device for silencing, muffling, or diminishing the report of a portable firearm, including any combination of parts, designed or redesigned, and intended for use in assembling or fabricating a firearm silencer or firearm muffler, and any part
intended only for use in such assembly or fabrication.

Numerous paintball and airgun silencers tested by ATF’s Firearms Technology Branch have been determined to be, by nature of their design and function, firearm silencers. Because silencers are NFA weapons, an individual wishing to manufacture
or transfer such a silencer must receive prior approval from ATF and pay the required tax. See also “What are the required transfer procedures for an individual who is not qualified as a manufacturer, importer, or dealer of NFA firearms?â€Â&#157; and “How does an individual obtain authorization to ma
ke an NFA firearm?â€Â&#157; for application details.

If you have any further questions as to the classification of a paintball or airgun silencer, please send a written request to ATF’s Firearms Technology Branch.

[18 U.S.C. 921(a)(24), 26 U.S.C. 5845(a), 27 CFR 479.11]

To clear this all up, it is considered a firearm silencer if it is readily available to be attached to a firearm in your possession. If you make this, and have a real firearm that it could be easily mounted on, it is legally a silencer because of "constructive intent". If you make this and don't own a firearm, or don't have any that it would readily fit, you're fine. All the regulations are a little blurred, but that's typically how it holds up in court. Best bet is to make it ONLY if it will not fit any firearms you own, and to permanently attach it to the airsoft or pellet rifle so that removing it would render it "destroyed".

In most of the United States, neither an airgun or a paintball gun are considered firearms (they lack the "fire" part). However, I know for a fact that in the Soviet Republic of New Jersey airguns ARE considered firearms, and a firearms license is required to own one. That's right; in NJ you need a gun license to own the Red Ryder BB gun from "A Christmas Story". No exaggeration. One of the many reasons I now reside in PA.

If you are in Bloomington, MN anything that fires a projectile spring driven, compressed gass driven or gunpowder driven are considered firearms. Ask me how I know.
