Selling Unregistered Silencers

Yeah, that title may be a little on the sensational side, but this is actually a pretty good example of how ridiculous US gun laws are. We all remember the Econo-Can, the registered adapter you can buy that threads an oil filter onto your .22lr firearm and makes a rockin’-awesome silencer. As the adapter is the registered part, you can buy new oil filters as the old ones wear out. In theory, at least, since the ATF appears to have an issue with replacing parts. But if you don’t want to wait the 10 months and pay for the specialized adapter, it turns out that Amazon is helpfully selling an identical part for a mere $20. In fact, you can make a silencer from parts lying around in your garage if you put your mind to it. Probably not legal, but physically possible. Which should make you stop and realize that gun control doesn’t actually work in a world where just about every part and adapter your little heart desires can be bought on Amazon or printed on a 3D printer.

    Wait, what? Is this legal for me to buy?

    1. avatar JoshinGA says:

      Buy, yes. Use with an oil filter on your gun as a suppressor? I believe that is a felony.

      1. avatar Jim Barrett says:

        It is. According to ATF, using anything to reduce the sound of the firearm that has not been properly registered and paid for is a no-no

        1. avatar Michael B. says:

          Meh, not all that interested. Seems too gimmicky for me.

        2. avatar Nathanredbeard says:

          Not really MB. look through vids on youtube (I would link but YT is blocked at work) and you can see that these things work great. If you’re under the radar, you could easily possess the adapter and filter and be ready to go in a SHTF situation right away (or for clandestine assasination operations, but I digress…)

      2. avatar Leo338 says:

        It’s only a felony if you get caught.

        1. avatar Chris from Iowa says:

          Technically it’s a felony before you get caught and you become a felon after.

        2. avatar theaton says:

          Technically the law that makes it a felony is an Unconstitutional law and is thus not really a law so it is in fact not a felony.

        3. avatar Jake says:

          Technically enforcing this law is more illegal than the thing the law purports to make illegal.

          That’s what the criminals and the left say too……

      3. avatar Yeah Right says:

        Yeah… using an oil filter makes it a felony… so better to not make KILLING SOMEONE a felony and all….

    2. avatar dan says:

      I mock you all,,,, atf snakes say this to the zombies….my masters say is can or cant do this or that, good 4 you slaves!

  2. avatar Don says:

    I’m pretty sure the oil filter that comes with the econocan is legally part of the suppressor, and switching out is considered manufacturing a new suppressor, and uncle Sam cares.

      1. avatar Matt in FL says:

        While I appreciate your incredibly eloquent and well-thought-out response, the FTB letter linked both in the post above and in the comment below this one disagree with you, and since they’re them and you’re, well… you, I’m gonna go with what they say.

        1. avatar Frank says:

          Yeah, I just realized that. Too late to delete the comment now.

          When word of this econo-can first came out their position was that since the oil filter is not the registered part it could be replaced by the user.

        2. avatar Matt in FL says:

          My understanding was that basically as soon as FTB heard about people actually selling these as serialized silencers they said, “Ummm… no.”

          They’ve probably been around, quietly, for a long, long time, just like the linked ones on Amazon. The difference was someone trying to make it official.

        3. avatar Afghan Vet says:


          Yeah they’ve been around for awhile. There is an instruction for making an oil filter silencer in the U.S. Army improvised weapons manual fron 1963.

    1. avatar Don says:

      Oh, when I say “pretty sure” I mean to imply I looked it up on the manufacturer’s website and cross checked with the ATF. If there was a successful litigation one way or the other then I’d say I’m “sure”. If I’m just making things up… then I’d likely not comment to begin with.

      1. avatar Don Sucks says:

        I’m pretty sure your full of shit! Yeah go ahead and check, I looked it up and cross referenced it!

        1. avatar Matt in FL says:

          You necro’d a five month old thread for that? To insult someone who posted a factually correct statement? What are you, twelve?

          Truly you are an asset to this community.

    2. avatar Yeah Right says:

      It is clearly an adaptor for my car… and a larger oil filter… nothing illegal here… keep on moving… nothing to see….

  3. avatar full.tang.halo says:

    Nick you might wanna check out the most recent opinion letter on the oil can suppressor.

    Until a documented atf ruling letter for the masses is made this only applies to the original submitter, but they do indeed seem to care.

    1. avatar Nick Leghorn says:

      Didn’t see that one. Thanks!

      1. avatar Michael B. says:

        I’d also like to point out that the company selling these has such a sketchy web presence that I actually think that they might be a front.

        A paper company? Out of a house?


        1. avatar William says:

          Good call.

        2. avatar Wade says:

          I checked it out and came to the same conclusion. But the question is; a front for what?

        3. avatar Scott Henson says:

          The “SMELLS. LIKE. BACON.” part would mean he thinks that they are cops.

  4. avatar Tyler Kee says:

    Do you think if we (TTAG) filmed a video of us doing this, we could get the David Gregory treatment? Because we would be doing it to make a point?

    1. avatar Ryan Finn says:

      Somehow I think that the Feds wouldn’t feel that it was a waste of time to prosecute

    2. avatar Brian in Seattle says:

      Better yet, get Gregory to show how easy it is to construct one. Preferably in a studio in DC. The ATF couldn’t possibly give him another pass.

  5. avatar Jim Barrett says:

    The interesting question is whether or not someone could buy the part from Amazon, then fill out Form 1 as a maker of a silencer. One way to play this would be to make a housing that encircles the oil can. This housing could then be engraved with the S/N. Silencerco does this with their sparrow. They have an outside sheath which bears the S/N. Inside is a second housing that holds the actual suppression materials. Should the baffles ever be damaged, Silencerco can affect the repair without impacting the serial numbered part.

    So, assume you go through this, create a housing, file the form 1, presumably, this would let you replace the sound baffling material. Of course, the ATF could also say that since you don’t hold a SOT as a registered manufacturer, the Form 1 only allows you to create it in the first place, not to actively maintain it.

    A Sparrow from Silencerco will run you less than $400 from and figure paying another $25 to a local FFL to do the transfer. So, given the fact that you either have to fabricate the housing yourself or find someone to do it, you need to decide whether the money you save just buying a legal silencer is worth all of the hassle.

  6. avatar Henry Bowman says:

    That’s not a suppressor. It’s a solvent trap. See, that way you can capture your gun cleaning solvents in an oil filter and then reuse them. Way to “Go Green”, Amazon!

  7. avatar Rambeast says:

    It is not illegal to posess unless you intend to use it for purposes outlined in current law. Same applies to AR pistols and SBR rules. You can have an 8.5″ upper for your pistol, but when you attach it to a lower with a stock, it becomes a SBR, thus making it a felony.

    Proving intent is difficult in a lot of cases, but when it comes to the BATFE, it is the default position, and you will likely have to prove othewise.

    1. avatar elliot says:

      I think you may be incorrect. My understanding is under constructive possession you cannot own a SBR upper with out a dedicated SBR lower. If you own a SBR upper and a rifle lower or a complete rifle than you’re considered to have a SBR under constructive possession. This is why people who do 80%/paperweight parties dont allow SBR uppers on the premises.

      1. avatar Nathanredbeard says:

        See US v. Thompson-Center Arms Company (1992). My understanding is as long as you own all the parts to assemble in either a rifle setup as well as an SBR setup, it is not considered to be constructive possession. I am not a lawyer, don’t own a pistol upper, not legal advice, blah blah blah.

        1. avatar Matt in FL says:

          I’m also not a lawyer, but I did a bunch of reading on this a few months ago (that I can’t find citations for now, sadly), and it was also my understanding that there was a “presumption of innocence,” if you will. By that I mean that if the collection of parts you have can be or are assembled as a legal item, the presumption is that they would be. As an example: complete rifle + possession of an SBR upper would be OK; or possession of an SBR upper AND a rifle upper AND an unattached complete lower would be OK. However, an SBR upper and a complete lower WITHOUT a rifle upper would NOT be OK, because there’s no legal way to assemble the parts you have.

          I know quite a few people who own multiple non-SBR ARs, and the idea that they would have to divest themselves of all of those rifles if they came into possession of a single SBR upper is simply illogical.

          If there is someone who can offer an actual legal opinion or citation, I’d love to see it, since I can’t find any of my research on the subject at the moment.

        2. avatar Nathanredbeard says:

          Matt, that’s why I listed the case above. The long and short of it is, the ATF said that TC providing a 16 inch barrel and stock to change out with your existing TC Contender pistol was unregistered transfer of an SBR because the components could be assembled with the stock and the pistol barrel (even though it specifically was printed on the stock DO NOT DO THIS). SCOTUS disagreed, their finding in brief is essentially what you wrote about multiple assemblies, as well as lenient interpretation because of the criminal penalties and ambiguity of the statute. Except it’s way more complicated and full of legalese.

        3. avatar Matt in FL says:

          Ah, that’s right. I’ll admit I skipped over your citation because it sounded familiar. Turns out it had exactly what I couldn’t find. Thanks for the clarification.

      2. avatar elnonio says:

        Elliot: you and Rambeast have slight differences in the fact pattern, so you are both right.

        If you have an SBR upper, no registered SBR lower, and a regular lower, you are in constructive possession: you have all the parts to make an SBR, and no legal way to configure what you have on hand. Whether you put them together or not is beyond the point.

        If you have an SBR upper and a registered SBR lower, as well as regular lowers, then you are OK as long as you never actually put the SBR upper on a regular lower. In this case, you have the ability to configure the items legally or illegally, but only actual illegal configuration is punishable.

        If you have an SBR upper, a “registered” pistol lower, and a regular lower, you are still ok because you can configure the parts legally (there is no maximum length for a pistol upper, but the lower does have to be manufactured as a pistol lower). It should not make a difference whether you have a regular upper.

        You could also have an SBR upper and no lower whatsoever, and still be OK, since an upper is not the SBR, only the lower is, and you can’t have constructive possession unless you possess all the part needed to make the firearm (for ATF purposes, having a stripped lower would trip their wire).

        By the way, this only works with ARs and other firearms where the lower receiver is the firearm. Compare with a SIG 556: why the upper is the firearm on those is beyond me. For instructional purposes only, consult an attorney, or pay me a retainer if you want Texas-specific advice 🙂

  8. avatar Shire-man says:

    I keep wanting to buy a couple of these to put back in the safe as I suspect they will end up like the old DIAS and that little attachment to put plastic bottles on as “solvent traps.”

    Same reason I got a slidefire stock. Not because I care to ever use it but because the way it flaunts danger so awesomely makes it very collectible to me.

    I just dont want to end up on some list or experience a “constructive possession” raid for ordering one.

  9. avatar Matt in FL says:

    I checked out Infinite Product Solutions other items, and I had to laugh. Guys, you’re stretching the bounds of plausible deniability on some of these items. To wit:

    CNC Solvent Trap 13/16-16 Oil Filter Adapter Ruger 10/22
    MADE IN USA! High quality CNC machined aluminum oil filter adapter. Our machining is second to none. Just check out the pictures. Now you can cleanly and efficiently clean the barrel of your Ruger 10/22 without having thread the end. Keeps stinky solvents from getting all over. Shown fitting on the stainless barrel of a 10/22 Takedown. Outer threads are 13/16-16 for most oil filters. The common Chevy 350/5.7L filter should fit with this adapter. Not intended for bull or threaded barrels. The set screw included has BRASS tip to keep from marring the the barrel.

    1. avatar J says:

      That’s just plain funny!

    2. avatar Michael B. says:

      I looked at their website (which has nothing under their ‘About Us’ section), researched their company history, etc.

      Only Infinite Solutions I can find is a paper company run out of a house in Hampton, VA.

      I think TTAG might’ve stumbled upon an ATF sting operation.

      Either that or Project Mayhem is real.

      1. avatar Henry Bowman says:

        Not sayin’ you’re wrong about a sting, just that here’s the site.

        1. avatar Michael B. says:

          And look at that site. *adjusts his tinfoil*

          Maybe I’m just a bit too squirrelly.

      2. avatar Matt in FL says:

        Wouldn’t that be funny. I found a website (, but it’s pretty thin.

        The paper product thing makes sense, because if you look at their Amazon offerings, other than the 4-5 “solvent traps,” they sell books. It appears they’re a small-run publishing house.

        I would buy from them with great caution.

        1. avatar Michael B. says:

          Yeah, I saw that.

          *passes Matt the tinfoil roll*

        2. avatar Matt in FL says:

          To be clear, if I saw these at a gun show, I’d buy a couple-three, for cash, and throw them in the bottom of my toolbox and then forget I had them. File it under “You never know.”

          But in no way am I ever buying them from Amazon with a credit card and getting involved in interstate commerce.

      3. avatar William says:

        Or working jointly with ONI? It sure stinks of an entrap… er, sting.

      4. avatar nerd_nurd says:

        Funny that that says Virginia, but if you look at their “returns” page, it lists an address in Bakersfield, CA, with an LA (possible mobile) phone number.

  10. avatar Layne says:

    It’s actually illegal to attach any silencing device to your gun at all, even if you never fire it. Thus installing the ‘solvent trap’ when it’s known to be identical to the ‘econo can’ cannot possibly be legal, even if you only use it for the “intended purpose” (wink wink).

  11. avatar Aharon says:

    Someone please explain to me the mechanics of how the device fits onto the barrel without the barrel having work done on it to join with the threads on the adapter. If the adapter is threaded how can it be joined to the barrel?

    1. avatar Matt in FL says:

      You still have to have a threaded barrel. Well, except for the 10/22 version I copied above, as it fits over the barrel and has a set screw.

      1. avatar Aharon says:

        Thank you.

  12. avatar Matt in NC says:

    I have one of these. And I havent spilled a drop of sovlent or any other chemical since I bought it. It works equally well on my MP22 pistol and my AR. A fantastic little device to play around with, especially those that are very concerned about our impact on the environment.

    1. avatar Michael B. says:

      Did you buy it from this company?

      1. avatar Matt in NC says:

        I bought mine on ebay, and have been very pleased with it.

        1. avatar Matt in FL says:

          Thanks for the link.

          That oil filter shown in the third photo, the Fram PH4967, is exactly what’s sitting on my car outside right now.

        2. avatar Matt in NC says:

          Dude, as a car guy… buy something other than Fram. We’ve seen lots of problems with Fram filters at the dealership where I work. There was even a TSB about them from Chrysler a few years ago concerning all of the issues Fram filters can cause.

        3. avatar Matt in FL says:

          I have a ’94 Celica with 234k miles that’s had Fram filters on it nearly its whole life. I’m curious about what those issues might be.

        4. avatar 16V says:

          Frakkin’ Ruins All Motors is the old saw.

          If you cut them open and compare them to better filter, they have a really low pleat count and the material will seem sketchy – because it is.

          That said, lots of people get away with them. If you have a decent engine, and decent oil change schedule, you’ll likely be fine. A ’94 Celica with the 2.2 should easily go 300K as long a it doesn’t sludge.

          If you really want to go down the rabbit hole, there are several oil enthusiast (I swear) sites out there. ‘Bobistheoilguy’ is a good one for general knowledge.

        5. avatar Matt in FL says:

          I’ll check it out, thanks.

        6. avatar Matt in NC says:

          Perhaps the filter for your car doesnt have the same style valving inside. Chrysler has a lot of problem with the Fram version of our Mopar filters not opening correctly and having noisy start up. Even caused engine failure on some Cummins engines in the 90s. Heres a couple of links to look at. Pretty interesting stuff, if youre a car guy.

          Best of them all:

        7. avatar Matt in FL says:

          Wow, there goes my afternoon. Thanks for all the info-links.

  13. avatar J says:

    If I ever need to draw my weapon, I am not going to be particularly concerned about the noise. There will be greater issues to deal with, during and after the shooting.

    I certainly don’t want a legal silencer simply because I don’t want to “court” the Feds and I really don’t want to fire any of my weapons with an oil filter suspended oh so gracefully from the muzzle end.

    It is nice to know we can create these “field expedient” devices but we have always known that.

    1. avatar Matt in NC says:

      Suppressor devices are fun to mess around with. For me, it has zero practical purpose. It does however bring a smile to my face every time I use one, so why not? It’s a novelty to me, but if I had neighbors that didnt want to hear the noise and I shot outside? It might be worth the investment. Does anyone have any statistics on how many crimes are committed with a surpressor every year? It has to be damn near zero.

  14. avatar Aharon says:

    I find the information interesting. However, I would not seriously consider the concept unless we entered a SHTF TEOTWAWKI situation.

    1. avatar Nathanredbeard says:

      I’m in the same position. If I want a silencer, I am going to get a permanent one, not one that will be rapidly degraded. But, it would be nice to have the components tucked away with a 10/22 Takedown in the SHTF cache.

    2. avatar Dustin Eward says:

      And I;m sure mail order internet stuff will be available then… The point of being prepared is that you do it in advance..

  15. avatar BlindKyle says:

    Check out the “frequently bought together” on the amazon page, a Walther P22 thread adapter. Hmm. . .

    1. avatar Pro-Liberty says:

      Well, people need to clean their rimfire pistols, too.

  16. avatar JD says:

    As if the heavy steel golf ball launcher listed next to it wouldn’t be a superior platform. Perfect for serial number as previous poster noted. These traps have been around forever, I saw an antique brass one for a turkish 8mm mauser..
    Bet you could make one with polymer putty just centering the muzzle threads between the filter’s threads (filter suspended rigidly) with petroleum jelly as release agent, and filling like a creme donut & then adding external support with more putty. Or on the 3D printer with printed threading. Or taking dies to a nylon bushing.

    1. avatar Dustin Eward says:

      I donated my design to defcad before the ITAR crap shut them down. If you dig up their torrents you can see it.

  17. avatar Sammy says:

    Do they make holsters for guns with the “filter” attached? You have to be careful, I still can’t find a holster that will fit my Ruger Charger with a bi pod and optics attached.

  18. avatar Thomas Paine says:

    well, that’s like buying cannabis seeds online. It can be done, BUT………

  19. avatar Drew says:

    Hey guys, I know I am a couple months late, but I just Googled our company and stumbled across this thread with some comments about us selling solvent trap adapters on our website To clear some things up – there are two Infinite Product Solutions companies. A paper co. on the east coast and then our company on the west coast. We are pretty new and our website was pretty undeveloped, so I completely understand the lack of trust in the validity of our company. I would like to note that this product isn’t illegal at all to buy, sell or use as a cleaning part.

    I just thought I’d throw a little word in in-case there are still those who wonder if we are a real company. We are cometary real, very passionate about what we do and are doing our best to provide excellent products to sportsmen everywhere.

  20. avatar Reg Thibodeau says:

    I attempted to buy several of these from Dustin Eward at I received a receipt from his web site, indicating my order was completed (I’m willing to provide proof of that for anyone who doubts it), but my card was never charged and the adapters were never shipped. I contacted Dustin several times (emails are available as well) saying he would “look into it”, but never got a further response.

    Makes me seriously wonder if adapters is an ATF sting where purchasers will be listed (for attention from ATF at a later date, perhaps?), or if it is simply some other sort of scam. My ersonal opinion is that you would be best served by staying away from his web site, and advising family and friends to do the same. I haven’t looked to see if the Amazon source is actually Dustin Eward, but I imagine it may well be.

    1. avatar Dustin Eward says:

      It’s not. I don’t sell to people who ask question about how to make a silencer out of it because they don’t know how and they’d really like to rope me into a conspiracy of helping them break the law. Taht’s why you were never charged. That’s why I never sent them to you; you expressed open criminal intent and I wasn’t going to be party to it. So here you slander me with half the story…

  21. avatar Dustin Eward says:

    To clarify some of this…

    For purposes of the Registered Thread Adapter, the ATF considers the filters to be user-replacable wipes. This is obvious BS because the thread adapter itself very obviously cannot be performing any sound reduction.

    I was a bit confused about it at first, myself. But some events ufolded as I manufactures Solvent Traps taht began to clarify it.

    On the surface, it appears that the ATF is helping us along by bending the rules a little.

    However, I received death threats from people claimign to be “From the ATF” back in late June of this year.

    The shoe that more likely fits is that someone cuaght hell for this as the smell wafted nearer the top of the food chain. The unregistered ‘solvent trap adapters’ were fantastically overpriced, clunky, and generally just crappy and expensive. I entered the market and killed the price Competition a la Capitalism. Bam, I got death threats.

    I think the parties responsible for bending this rule for the original manufacturer were getting kickback and I put na end to that. It got popular and thent he heat came down on the people whp aren’t getting their kickback anymore so it isn’t worth it to them to take the heat now…

    Sure, there’s a lot of conjecture there… But it’s the only shoe that fits. The bottom line is that Solvent Trap Adapters have evolved beyond oil filters (4003 fuel filters now) and are a lot cheaper while also being perfectly legal, as logn as you don’t use them for silencers. The law is absurd, those who created it and enforce it are equally absurd.

    The only difference is what you do with it. If you don’t shoot through it, no crime. The object itself is no different. I compare it to owning a gun versus shooting someone in the face with it. It’s not a crime to own a gun. It’s not a crime to own the adapter.

    The really interesting part is how would they consider evidence? If you’re in possession of an oil fitler with a hole shot out the end… Doesn’t prove you used an unregistered adapter to do it, right? The oil filters are just wipes. Even if I had 10 of them laying around and the Feds showed up, maybe a guy with a registered adapter came over and that’s how they got all the holes in them? How could they prove otherwise?

    This lends further credence to my glass slipper. It screws them up in so many ways that I’m pretty sure they did not in fact create this rulng to help us out a little. It was an under the radar kickback scheme that got found out, thus the threats on my life for lowing the price so far.

    I still like to joke about the ATF impersonators who told me to take down my website ot they’ll “kill me and everyone I know.” That night. The ATF might be known for doing such things, but they don’t show up at 2AM and tell you about it… It obviously happened in an unoffical capacity either from the sellers whoa re mad that I lowered the price, the agents responsible for the scheme, of a comination of both. It’s the only shoe that fits and explains why I’m not in prison. I ruined the gravy train and put a LOT of egg on their faces. A false prosecution against me would only open up this can of worms much more publicly.

    1. avatar Dennis says:

      I agree! But could you do me a big favor and look into an order that was made and haven’t received yet, I’ve emailed several times? Thanks

    2. avatar Wihunter says:

      Sorry to resurrect an old thread. Only way I can try to get some help on this? Placed an order at, got my order email and debit card was charged a couple weeks ago. Emails sent asking about the order haven’t been responded to. Is Dustin Eward or Gregory Eward (per email address) no longer running the business but his website checkout is still running?

  22. avatar ken says:

    Its leagal to own the solvent tap adapters and a oil filter but its just not leagal to use them as a suppressor on your gun according to the atf…its that simple…cheez…I own a shit full of them

  23. avatar Daniel says:

    You can completely silence a .22 rifle using standard velocity rounds, which is a very attractive idea to preppers who plan to hunt small game as part of their survival strategy. And anyone who’s ever had to fire a pistol in an enclosed room in the dark knows that it’s a really good idea to have a suppressor on the end of that pistol in your nightstand too. 😉

    Amazon won’t show you, but if you look on eBay, you’ll see that thousands of these adapters have been sold in just the last three months. Just another indication that more and more people are losing respect for federal gun laws. These are not convicted violent criminals, these are regular people who no longer trust the federal government and don’t want them to know what they have. As long as you store this adapter in your bug-out bag where it belongs and don’t take it out in public and get stupid with it, there’s very little chance of ever getting caught with it on the end of your gun. And, of course, if the s*&t ever does hit the fan on a large scale, none of the government’s pointless nit-picky laws will be enforceable anymore anyway.

    This is really messed up guys. I agree that the gun laws regarding this are a bit silly and full of holes. Heck, I remember when President Clinton passed the “assault rifle ban,” which was a joke and a play on words, YET you could still buy stamped metal on eBay that could be folded into an AK-47 receiver. Ridiculous.

    BUT NOT QUITE AS RIDICULOUS as actually doing it, or trying to make a stupid legal argument for “solvent traps.” Let’s be real: When you’re found with an oil filter filled with GSR, are you really willing to chance a felony for the chance to screw around? Cute work-around, but highly risky. I’d rather pay the tax stamp than sit in prison, thank-you-very-much.

      That gun ban did wonders for the gun industry, lol. It got rid of a lot of surpluss items, like mags, ammo, and ect. It also helped boost gun sales. Also, the latest gun scare boosted gun sales even further, along with ammo sales in record numbers, lol. The US.Gov isn’t the smartest Gov in the World, if it’s trying to stop gun vilence, lmfao.

    Okay. Seriously, lets suppose you did this legally. First, you installed this on a handgun, and then attached an oil filter (again legally). You wouldn’t be able to see the sights on your handgun. Point shooting up-close wouldn’t be a problem for bigger targets, but you couldn’t shoot targets with this arrangement, or expect to hunt small game. Furthermore, the front end would be really heavy & the whole arrangement out-of-balance. Basically worthless, but probably at it’s best with a .22LR pistol. The off balance problem will also suck with a .22 pistol. If you carried concealed, there’s no-way to hide a big oil filter under your belt, so the James Bond idea is out the window. On a larger caliber rifle, the noise reduction isn’t that great, but you might be able to use your sights or even a scope depending on how high you have things mounted. The trade-offs are really bad. You would be better off using a quiet .22 rifle with subsonic ammo, or even a pellet gun. YES, the ATFE will put you in jail for these things, but they are not too concerned because about this crap because they don’t work that great on rifles, and pretty much suck on handguns for all the reasons stated above. I wouldn’t waste my time. You can get a good .22 can for 300 to 400, and it will work very well. Good luck & please stay legal.

    i do not own a gun but from what i know a potatoes works just fine as a single shot silencer and with the proper tap and die one could make the threads cut a pipe in half weld some baffles in place and even a muzzle break these laws only stop honest people if somebody was planning on a killing spree they would also likely be planing on being killed or killing them selves or being caught by the police criminals do not follow laws just like a gun free zone is a target for a mass killing as they can expect to be only one with a gun sad but this how it works look up a guy called fpsrussia on youtube they have a no questions asked concealed carry you can walk around half dozen p90s in trench coat and by the looks of it one can pretty much own anything he fires a 40 mm machine gun in his backyard any acts of terrorism or major crimes in Russia well i doubt they would get very far

    interesting bunch of hype. What has actually been reviewed is great shipping, customer service, but little on product use. Video focuses on a small quite caliber, 22 for crying out loud, that really doesn’t compare to the enormous BLAST pressures from larger calibers. Research into US Patents on sound suppression reveals that the difference in larger calibers is hard to discern the difference. It is recommended that suppression of sound for larger calibers is almost a worthless cause. Sellers, when pressed about failures reply that “SUBSONIC” materials is what they recommend. So if you’re using subsonics, why bother in the first place.

    Creative comments ! For what it’s worth , if someone needs a Form mc330 , my business partner saw a sample version here

    90% of these comments are in left field. The ECONO-CAN Adaptor has to be
    treated just like a regular suppressor. It has a serial number and you have to pay the $200.00 for
    the “{privilege)” of being allowed to buy one. If you do not believe this, google “Hickock45” using
    the Enono-can oil filter legally.

  31. avatar Peter Szwed says:

    A couple of things;
    1) You cannot buy an adapter and add you own filter. Both parts must come from the manufacturer, be numbered alike, and be registered as a unit.
    2) You cannot change the filter yourself. The complete assembly must be returned to the manufacturer for filter replacement and serial numbering of the new filter.

    This is just my opinion but the idea that “solvent traps” are legal is a leap of faith based on hype and some bad info. Any prosecutor could easily show, in a side by side comparison with a similar item used as a silencer, that you just have an unused silencer. It’s the possession of the item that’s probably going to get you into hot water not it’s actual use. Not something I would risk my freedom on.
