First off, if you just got here you’re also going to want to read our other posts about the dual use muzzle adapters, the wix fuel filter suppressors and the Maglite suppressors. You also might want to have a look at some Books on How to Make a Silencer. Also, many of our visitors also want to know about how to make their own Tannerite exploding targets
We do our best to provide working links for your convenience. However, Amazon frequently removes these listings. Don’t be discouraged, the products are still out there, but they may be listed on Amazon under a new/different description to get around Amazon’s censors.

And now to our story…
It’s not an urban (or is it “rural legend” in this case) legend, and you can see for yourself in the videos. The thing not only suppresses sound, but it also allows the shooter to accurately and reliably fire his gun and hit the intended target.

“Econo-Can Oil filter Suppressor (Adapter) Demonstration
Of course, you will need to pay the $200 tax stamp if you want to be legal.
Some people don’t believe the Second Amendment permits federal regulation of suppressors and will never pay $200 for a tax stamp. Those people may be at risk of violating the law if they attempt to suppress their firearms without the proper paperwork, etc.
However, much like the idea behind the 3-D printer plastic gun blueprints (recently banned by the US State department,) anyone with a blueprint and a machine can make a part regardless of the law. Just like a car is capable of breaking the speed limit, the law doesn’t change the reality that the law may be broken. It is obviously possible to make a cheap and simple adapter that fits a threaded barrel to an oil filter. In fact there are a few of them available on Amazon for use as adapters for oil filter “solvent traps.” When combined with an oil filter this solvent trap is not intended to be used as a suppressor, but as a trap to catch cleaning solvents that may otherwise leak out of the barrel during cleaning and harm the environment.
So practically speaking, anyone with the right machine can make and sell this adapter legally, as you can see on the Amazon links above. Of course different threads require different adapters and filters. For example, it appears from our research that the AR-15 uses a 13/16 – 16 thread, while the .22LR models use a 3/4-16 thread. Although this can vary depending on how the adapter was manufactured, so if you want to buy one to use as a solvent trap make sure you match your threads or it won’t work. Also, some adapter designs reportedly work better than others. Since they are so cheap, you may want to buy a few and try each one out. If one works better than others at creating a tight seal, we’d love to hear about it. Some reviewers on other pages suggest using these adapters with a washer and gasket to make the perfect seal. They last thing you would want is to have a leak and let some solvent out that could have been contained.
In addition to the oil filter suppressor, many fans of The Walking Dead will recognize the Maglite Flashlight being employed as a silencer. There are now options for this available as well. We’re not sure if there are options the include a serial number for legitimate use as a NFA item, but we know the adapters are available on Amazon for use as a “Maglite solvent trap.” The Maglite, with a narrower diameter, would allow better visibility of your target than an oil filter so consider as well.
User Feedback – We’ve heard from a fan, who will remain anonymous, that these “solvent traps” do in fact work as you would imagine. He submitted a review of several different filters to use and even gave us pictures, which we will post along with his reviews. We have no way to verify his comments and so we consider this all to be fiction/fantasy/for entertainment purposes only. We recommend you clean your firearms unloaded to avoid any accidental discharges. His words:
I have taken some pictures of the long list(good enough) and short
list(best) oil filters for the two most popular solvent traps.
While getting ready to clean I have had NUMEROUS accidental discharges and I
can tell you that the tiniest filter is sufficient for any .22 lr. Fram is
my favorite brand due to metal body and interior, but plastic bottom. The
Fram PH4967 is the smallest and lightest filter that I have found to be
compatible and sounds about like a textbook falling over.
The best 5.56 filters I have found are Fram PH16 & Purolator L20195. So far
I have only tested from the $3.77 shelf and do not expect the fancy filters
to do any better.
Here’s what he sent along with his pictures:
The motorcycle filters are all metal and come in some pretty slick chromes and blacks.
The muzzle break pictured is an American Specialty Ammo 1/2 x 28 tpi that looks perfectly at home on my AR.
The plain adapter is a no-name Amazon special that locks it self on TIGHT. After firing, you WILL NOT be able to remove it W/O a wrench or multi-tool.
The smallest filter pictured runs perfectly on my Chiappa Little Badger and does not obscure the iron sights.
We do not offer legal advice other than to say that it is never wise to break the law. It’s even less wise to record or document yourself breaking the law. Hickok45 had his legal paperwork in order, you can bet.
Anyway, the oil filter suppressor does appear to work as a low-cost alternative to the $1000 suppressors in the market today. If you do decide to get an “econo-can” we’d like to hear about your experience with it. We’d especially like to hear how it and the oil filter hold up after a few hundred rounds of 5.56.
Another option to consider are the “Wix fuel filters.” READ ABOUT THEM HERE. They serve a similar function as the oil filter and the Maglite. We’d love to hear from some of you who have experience with these, and make some recommendations. It would appear that while these may be more expensive alternatives, they also have what appears to be a replaceable cartridge design and a much smaller profile. This smaller profile has a benefit of allowing you to see your sights while the filter is fixed on your barrel, should you want to.
Here are a some we found on Amazon. Make sure you read the reviews and comments and get the right filter for your threaded adapter.

We’ve found a few videos on YouTube that may also help with your understanding of how these products can help you recycle your cleaning solvents.
Make SURE you get the correct adapter. The NAPA 4003 needs a 3/4 NPT thread.
