I saw an adapter for putting an oil filter on a gun.

It was at the Wanamacher show last weekend.

I didn't stop to look. Just glanced as I walked by.

What is it? How does it attach to the muzzle?

Re what is it? Some form of suppression? Legal until you actually put it on a gun?
 
You can use an oil filter as a pistol caliber suppressor. There is a company that makes an adapter for them - the tax stamp is more than the adapter. The downside is that the filter is only good for less than 100 rounds and you are supposed to send it back to the company to have the filter replaced with a "proper" serialized filter.
 
They are marketed as a solvent trap. DONT get caught with one attached to a firearm, and an oil filter with a hole in the end.
 
As mentioned, some people also sell the adapters as "solvent traps" without the tax stamp or serialization. Given how broadly BATFE has applied the doctrine of "constructive possession" to firearms, my concern would be that ATF would view possession of any oil filter or similar device and a "solvent trap" as a firearm suppressor and throw you in jail, regardless of whether either was attached to the firearm or used.

There is currently an ongoing lawsuit because BATFE classified the SIG muzzle brake as a firearm suppressor since it would work that way by adding an outer tube and endcap over the existing brake. If they feel that way about a muzzle brake and the amount of work to convert it to a suppressor, I doubt they'll have much mercy on a "solvent trap."
 
They thread onto the muzzle. (You have to have the barrel threaded.)

They're marketed and sold as both questionable "solvent trap adapters" and (so far) legal "oil filter silencer adapters".

As Bartholomew Roberts mentioned - the solvent trap version isn't something I would want to mess with. There's a whole lot of "constructive possession" risk with that crap.

At the same time (also mentioned by BR), the legal version cannot legally be "repaired" by anyone that doesn't have a manufacturer's license. So, once the serialized oil filter is shot out, you have to send the whole thing to a licensed manufacturer to 'rebuild' it. And possessing extra oil filters that can thread onto your adapter might even be argued to be "constructive possession" or "manufacturing without a license".


Bottom line:
They're a novelty items with a whole lot of potential for trouble.
 
ATF has given the nod to the solvent trap adaptor. Its kind of a silly idea but legal at this point

If the oil filter you put on the end to trap solvents ALSO has a bullet hole in the end... You got problems. Like 10 years in prison and a huge fine

The company sells the adaptor as a muzzle brake that has external threads to match a std oil filter. The legal and approved reason to have this is so you can clean the gun without solvent and crap dripping out of the muzzle. Ahhhhh OK

That works i guess

The way it becomes illegal is to attach an oil filter and then shoot thru it. Based on the videos on the web of the suppressor version. This works ok as well.

Seen one way its a legal TAX STAMPED very cheap way to suppress a small cal firearm. But it doesnt make a bunch of sense to me. You are paying the $200 stamp anyway. Spend 200-300 on a REAL suppressor and enjoy

Seen the other way, its a pretty silly cleaning gimmick that could land you in prison if you use it as a suppressor

All that being said. There are utube vids out there that show the legal ones in action. Works pretty good on 22lr and such
 
If I owned one of those, the only oil filter I would have would have solvent residue in it, and NO hole in the end.
I actually could see the utility of such a contraption for cleaning corrosive residue in my rifle barrel.

Have you seen actual documentation of this? Just because they're for sale and the ATF hasn't broken down the doors yet, it does not follow that they have "given the nod" to the solvent trap adapter.

(I've heard whispers that the opposite is true. Which, as information, is worth exactly what you just paid for it.)

For me, I wouldn't be caught anywhere near one of these things. I absolutely believe that virtually every person who buys one intends to and does use them as an illegal, unregistered silencer.

The thing is pointless. It's (yet another) example of a Rube Goldberg Machine. There are a dozen free and easy ways to do the same thing, along with a dozen commercial (and similarly or cheaper priced) products that ARE NOT suspiciously close to and in fact ALSO MARKETED AS silencers.

No way, no how.
 
Anybody dumb enough to get one of these is dumb enough to post a video of it on YouTube.

Important safety tip :

Be sure to step completely inside the jail cell before they close the door on you, you can hurt yourself that way.

Like................?
 
Um... A soda bottle and electrical tape, plastic adapters for soda bottle, a towel under the muzzle, a pan under the muzzle, just about anything really.

Oddly, I've cleaned a whole bunch of guns, no doubt hundreds of times, and I've never attached anything that can be used (and especially is marketed) as a silencer.

How many ways can you clean your gun without something that's marketed as a silencer?

Every single way, ever, in history, until these things were invented.
 
In a past life when I was young and dumb, I got caught up in something similar to this. The ATF came knocking on my door. I was up for 10 yrs in prison and over $100 K in fines!!

Guys, don't even consider stuff like this. I'm telling ya, the Feds take this stuff very serious!
Play by the rules and do it legal, please!

Some folks will use rubber bands and a ziploc bag on a rifle to catch spent patches and residue. Brownell's has a doodad that will attach to the barrel for this as well.

The difference is, those approaches don't resemble an apparatus for silencing the weapon.

We've discussed the matter in depth several times in the past. The people selling them are doing so under a "nudge and wink" approach, and it's more than a little irresponsible.

Yep, and they work surprisingly well. From what I understand, the threaded adaptor is bought and registered with a tax stamp, as a suppressor and then the oil filter is put on to do the actual suppressing.

It's not a great idea if you want to use your sights, but it'll certainly quiet a gun down.

You wanna let us in on what the actual result was... I'm guessing not 10years and 100k!
 
Brian,
A pop bottle can also be used to form a suppressor, so you have.
Hell a towel wrapped around the muzzle does will also(until it burn up).
The first suppressor design I learned was made out of duct tape and toilet paper.

On the legal registered adapters I've not heard about the thing being needed to be mailed back to have the filter changed. Quite certain that wasn't required at first.

Nope. Check the link thallub provided.

The silencer is the device (including any functional part) that does the actual suppression. That's the oil filter, and that's the part that has to be registered.

The "adapter" is just another muzzle device. There is no way to register it, and no point in attempting to do so.

Some sellers of those adapters have made claims to the contrary, but they have been unable to provide any documentation from the ATF to support their claims.
