This subject used to be covered under our “Oil Filter Suppressor” page, but we’ve decided to give it the space it deserves.  In addition, we’ve given the “Wix Fuel Filter Suppressor” it’s own page as well.  You may also want to read about the new IMACS – Integrated Muzzle Adapter Coupling System.

If you’ve seen The Walking Dead, then you’ve probably seen some of the characters on that series using what appears to be a Maglite flashlight tube as a suppressor.  In that scenario the zombies (and probably hostile humans) are attracted to the sound of gunfire, so remaining quiet and stealthy is a must for survival.

The Maglite Suppressor

The Maglite Suppressor

We don’t know how effective this setup was, but it seemed to get the job done for Rick and company.  But could this work in real life?  The short answer is, yes, it can and does suppress the sound of a gunshot.  The ATF might want to talk to you about your suppressor, and verify you have a tax stamp if required, but for the purposes of educating you guys on how Rick might have made his own suppressor, we’ll ignore all that legal stuff.  Besides, there are other uses for this device, such as the legitimate and legal use as a “solvent trap” for containing harmful gun cleaning solvents.  Again, this is all just for entertainment and we don’t encourage you to break any laws.

As we discuss repeatedly, whether making a suppressor from an oil filter, a fuel filter, a flashlight, or anything else, what you really need are two things; 1) A can or tube-like expansion chamber – preferably with some media/baffles in there to absorb the expanding gasses, and 2) a threaded adapter to connect that can or tube-like expansion chamber to your barrel.  The tricky part is always making certain you are matching the right threads for both your barrel and the can you have chosen.  Remember that there are D cell and C cell Maglites – so buy the right adapter.  That is where most of us lack the tools and ability – to build our own adapter.  Once you have the right threaded adapter, the rest is probably within the grasp of the average man’s tools and abilities.  We recommend you spend a few minutes researching the threading and materials and looking up some reviews on Amazon.com or elsewhere prior to spending money.  Also, viewing videos on YouTube can be helpful as well.

These tubes are now available as kits.  That’s right folks, complete threaded tube kits are now available.  These things are about as close to the real thing as you can get.  In fact, they were never intended to be working flashlights at all.  They are just tubes with threaded ends.  Of course, they won’t do you much good without the……well, we will get to the inner workings soon…

Any of the above adapters appear to thread to your 1/2 x 28 (for .223 and 5.56) and the C cell one pictured directly above appears to also come in a variety of other thread sizes including 9/16 x 24 (which we believe would be suitable for most .40S&W and 10mm barrels) and 5/8 x 24 (which we believe would be suitable for most .308/7.62mm barrels.)

So once you have your threaded adapter, thus enabling the coupling of your barrel to the Maglite for use as a solvent trap, you’re well on your way.  From there, should you decide to attempt to convert it into a suppressor, it’s a do-it-yourself project and you take all the risks and you are responsible for your own success/injury/jailtime.  Again, we recommend you use the Maglite as a solvent trap only, unless you have met all the ATF’s requirements for manufacturing a suppressor.  We suggest you obey all laws and we do not offer legal advice.

The final step, from which there is little other purpose but to suppress a firearm, is too add the “freeze plugs”, “cups” or “spacers.”  We do not offer legal advice, and could be wrong but it is our unprofessional opinion that the ATF will see them for what they are, sound suppressing baffles.  The purpose of these things is to slow down and contain the expansion of…well you know.  Intent may not even be required, if you have these parts assembled together, or even in close proximity, you run the risk of being accused of having a suppressor without a tax stamp.  Do your own due diligence.

Note: Again, simply possessing these items in proximity to the above parts and a firearm that they may thread onto could possibly be considered by the ATF as possession on an illegal suppressor, or intent to manufacture one.  (See video below) You’ve been warned.

There are a few options available out there, in various stages of the DIY freeze plug process.  From top to bottom, in order of how much work is left to be done:

Maglite D Cell Solvent Trap Freeze Plugs 34.3mm 1.350″ (10) Center Marked

10 Freeze plugs that fit maglite D cell body. 1.35 diameter. Use as filters for solvent trap. Steel plugs, made in USA. They have been center marked for those without a centering tool. The mark may vary .010 at most, so I recommend drilling them out with a small bit, 5/64, and work your way up. I only drill a 5/64 hole to begin with. Pressing a cone or ball bearing in them opens the hole up to about 3/16. This will allow you to measure and adjust center if needed. These fit perfectly in the SD tactical tubes. These also work as battery spacers in larger D cell Maglites and I have used them to fit 2 CR123 batteries in a 3D light. Comes with detailed instructions on how to form into CR123 spacers. Includes information on tools required and some more common substitutions that may be used to form a cone in the center. Includes pictures and examples of various sizes. If you see anything missing or a way to improve the process please let me know. I’m always looking for ways to make it easier for everybody.

If you’d like to spend a bit more money, you can find a few guys out there who are willing to put some of the materials together for you.  These guys may or may not know what they are doing, but they probably know more than a complete newbie.  Caveat Emptor!

Here’s a video from one guy making Maglite suppressors and also selling parts for you to make your own Maglite suppressor.  He mentions a conversation he had with ATF agents on the subject.  According to him, the ATF says “solvent traps” are perfectly legal, but when you start building baffles, you enter an area that could get you in trouble.

We recommend you learn what you can from watching others on YouTube before you go off and try this on your own.  Just pay attention to the law of the land (The ATF/NFA) and the laws of physics.  Running afoul of either of them could give you a really bad day.

  1. Worst and most unprofessional comment section ever. The people that have legitimate questions almost never have them answered, and instead they are followed by people trolling just looking for a fight on politics etc… How about actually contributing instead of mouthing off guys?

  2. No the democrats are worst they have been taken over by communist party.
    They are doing what Nikita Krushchev said. They will take us over without ever firing a shot .
    He said “your children’s children will live under communism. You Americans are so gullible. No, you won’t accept communism out right; but we’ll keep feeding you small doses of Socialism until you will finally wake up and find that you already have communism. We won’t have to fight you; We’ll so weaken your econemy, until you fall like overripe fruit into our hands.”
    As for global warming – nothing man can do to start or stop it. If there is any it is part of the design, it has happened in the past. As for the moon landing I think we have been there.
    I have never got a job from a poor man. I am in favor of tax cuts for all. I am for taxing everyone
    No one should get by tax free we need a flat tax . Everyone should pay the same rate, it’s not fair for one to pay 12% and require others to pay 60%. We are 20 trillion dollars in debt. We owe the federal reserve to use our money. End the Fed. It was unlawfully ratified. Let us print our own money backed by gold silver. End the UN and get it out of the USA. Have term limits for congress and give them a wage more comparable to ours. But we also must cut government spending, end foreign aide, end all the bs programs the Feds pay out. close the boarder, stop all potential Muslim terrorists from entry. No refugees. Just a few thoughts .
    Get rid of RINOs and communists in democrat clothing. Anyone that is for any thing the violates the constitution having taken an oath to defend it should be charged with treason.

  3. What length d size tube is best for use on a 308 or 300 AAC Blackout?
    What size drill bit to use on the baffles and end cap for a 308 or 300 AAC blackout?
    If I get a 8″ tube and find out it’s still loud and later want to use a 10. ” tube instead can I destroy the 8″ tube and use the same serial number putting it on the new 10 or 12″ tube?

  4. As a man who believes everyone should own an assault rifle, at least a .223 with a semi-auto action, I deplore the comments about condors. They are a national treasure and worth more than any yahoo Trump voter or his goddamned kids. If you’re poor like me you’d be an idiot to vote for candidates from either party but the R’s are worse..dedicated to tax breaks for the rich and less benefits for you. (It’s good to think and read once in awhile.) So you think global warming and the moon landings were faked? You poor ignorant slob. Turn off the Fox! Or: Enjoy cheap beer on the porch of your trailer and keep voting for the guys that rob you. I’m totally in favor of milling lower receivers and making sound reducing equipment. I carry a pistol everywhere. (.40 or 9mm). I like 1911′s made from steel but I’m old and modern materials help my back feel better.

    • Nick you are wrong to think that Killary is better, you speak of gun ownership but Killary has stated in no uncertain terms that she wants to take our guns just like they did in Australia.
      She is so corrupt. At least trump known how to negotiate and deal with others, he knows how to build a team of advisers, he is willing to take advice from them . Not Killary , look at the ways she has treated her security, she is not nice, she is evil, corrupt and a liar. She endangered national security. How much worst will she be once she thinks she is queen .

    • you can’t forsake your children’s and grandchildren’s futures. The criminal deeds of Hilary far far outweigh the mere words of D. Trump. He has never killed anyone. Hilary wants to flood this country with Syrian muslims who hate America and have promised to reign terror upon us. After disarming us of course. She is demented and delusional. I couldn’t stand another 4 years of the media covering up the truth

  8. Dumb question. What do I use as a end cap for the suppressor. If I have a threaded piece that goes on the one side to connect to my riffle what caps the other side the bullet comes out of and where do I get one. Or do I just use a threaded cap for both ends. Please help!

  9. I don’t understand why responsible gun owners have to jump through hoops and sing and dance for the ATF just so we can own suppressors and SBRs. It’s not like either are used very often in crime, and the criminals who use them certainly don’t care what the ATF thinks.

    Reply

    • Because there are cities in the US that have the equipment to effectively pinpoint a shooter’s location. Suppressors defeat that equipment.

      Reply

      • Again, it begs to question, if criminals don’t care about laws and tax stamps, how is this effective against anyone but the law-abiding? Like most any leftist policy, it does nothing to hinder criminals, and everything to hinder regular Americans.

        It is like saying that since cars are constantly used to commit crimes, we must have a special [$200] permit to have a muffler on our car. Otherwise, the world is safer if every car is as loud as possible so it can be heard from miles away and we know where it is at all times.

        • That actually was a big argument against electric cars vs gas cars a hundred years ago. Sneaky electric cars were running over people that didn’t hear them coming.

  10. I built one for my 5.56 AR-15 and yes it does work.
    I have the approved Form 1 and Tax Stamp which was approved in January 2015.
    It took 9 months almost to the day from submission to approval.
    While the gunshot is pretty much reduced to a POP, the supersonic crack is still pretty loud, but not loud enough to need ear protection.
    BTW, you can get a solid MagLite tube in stainless steel (no switch hole) internally threaded both ends that will match the MagLite end cap.

    • you can always make a smaller caliber than what you put down on your form one but you cannot go bigger. Best advice is to just put in the biggest you would possibly use it for.

  13. In 22 years of LEO, I don’t never delt with a crime involving, SBR’s, select fire weapons or an suppressor. Go figure. Needing a federal stamp for a SBR or suppressor is redundant.

    • You are either a LEO (law enforcement officer) or you are in law enforcement. “In 22 years of LEO” makes no sense at all and “I don’t never delt with” (now that’s redundant as well as ignorant as hell) makes even less sense. I seriously doubt you are Five-O, Four-0 or even Three-0, although you are definitely dumb enough to be a cop.

  17. Best baffles come from inside of a microwave oven magnetron. It’s a bit hard to take them off but the effort is worth it. 2 conical baffles in each microwave. Most are between 35 and 36mm.

    Reply

    • Jeeezus…. folks, whatever you do, DON’T be breaking apart microwave oven magnetrons!!!! The insulators you will have to break apart to get at those “baffles” can have beryllium oxide in them and will, if ingested via inhalation, kill you. Want your pistol or rifle to make less noise? USE EAR PROTECTION!!!

      Reply

      • Sorry, how does me wearing ear protection make the gun quieter?

        Reply

      • It’s true but beryllia ceramic insulator is dangerous only if is crushed and inhaled or ingested. Same case for the thorium tungsten filament. The “baffle” is just a copper covered conical metal washer. The microwave oven magnetron is not dangerous at normal use but, of course, we need to know how to handle it, to avoid radiation contamination. Thanks anyway for the warning.

          There’s no “radiation contamination” in a microwave oven. Microwaves are just radio waves — higher frequencies than most radio equipment but far below infrared light — which in turn is far, far below X-rays.

          The worst you’re going to do with a magnetron is give yourself a radio energy burn. You’re much more likely to simply electrocute yourself.

  19. lots of people like to talk down on these homemade devices, but they forget that there are places in America, large states, where no matter how clean your record, no matter what hoops you jump through, you will never be allowed to purchase such a device. In such places, we improvise. Why for a silencer? guess what the two biggest hoplophobe excuses for shutting down rifle ranges are? 1) lead in bullets being eaten by stupid condors and 2) noise. So if they don’t let us quiet down, but shut us down because of noise, what do we do?
