Ban Oil Filters! by Robert Farago | Apr 12, 2012 | 55 comments facebook twitter linkedin email [HTML1] And these are dangerous because . . . ? comments sumyunguy says: April 12, 2012 at 14:07 Oh my god! The horror.

You could hear the crack echoing off the trees. Reply Henry Bowman says: April 12, 2012 at 14:25 So, the adapter (which is merely a piece of plastic with both male and female threads, cut to fit an oil filter and barrel threading) is the suppressor!? Who could ever doubt the infinite wisdom of the ATF or the benevolence of the state it serves? Reply MadDawg J says: April 12, 2012 at 14:37 From the sites it looks like its made of aluminum not plastic Reply Henry Bowman says: April 12, 2012 at 15:02 You’re right, my oversight. Reply Frank says: April 12, 2012 at 21:07 So if I make a round aluminum “thingy” with both male and female treads on it, that just so happened to fit my AR-15 and an oil can as well as other things it would be considered a silencer? Reply Matt in FL says: April 12, 2012 at 21:09 Yes, and if you were caught, it would be illegal as hell. Reply Andrew says: April 13, 2012 at 16:11 so if I carry around a pillow or soda bottles with my gun can I be prosecuted for carrying around “silencers”? bah, TY U.S. Government… Reply caffeinated says: April 12, 2012 at 14:32 I may have to spring for one of those. Reply Van says: April 12, 2012 at 14:50 Pretty cool. I wonder if some filter brands work better than others. Reply Lemming says: April 12, 2012 at 14:57 I guess this explains the Purolator commercial I saw this morning Reply Ian says: April 12, 2012 at 15:20 That’s exactly what I thought. In fact, I thought he was posting the Purolator commercial or something. Reply Lemming says: April 12, 2012 at 16:24 Let me add that I’m driving a Camry that’s past its Bar Mitvah, despite never once worrying if my oil filter had a cardboard thingy or a metal thingy. I suppose the first shot with the silencer attachment would work better with the cardboard? Reply HSR47 says: April 13, 2012 at 08:26 Bar mitzvah? Hell, the Corolla I drive is almost old enough to by guns and booze, and I’ve never had that worry either. Matt in FL says: April 13, 2012 at 09:44 OK, I have to jump in here. My ’94 Celica just flipped 235k miles yesterday. Derek says: April 16, 2012 at 12:45 Ppffftt… I only recently got out of my ’96 Civic sedan with (are you ready?) 356,000. Guywithagun says: April 12, 2012 at 15:34 “And these are dangerous because . . . ?” …because when when a gun is fired with a suppressor on it, a child dies. Reply Jeff O. says: April 12, 2012 at 15:51 Also a puppy and a tree and a whale. And someone also gives a Happy Meal, without any of the healthy options and with a toy in it to a small child.

Reply V says: April 12, 2012 at 16:57 I believe you meant innocent and defenseless baby seals. Buuurr says: April 12, 2012 at 19:39 F*ck you, Wayru! And a f$ck you, Dolphu! *double Japanese flip* Sanchanim says: April 13, 2012 at 12:52 Ok I just spewed coffee out my nose here!!! Buuurr says: April 12, 2012 at 16:05 Fantastic. Reply Vorpalis says: April 12, 2012 at 16:15 How do you aim? You can get tall sights to aim over a regular silencer, but you’d have to get, like, two inch-tall sights! Reply Guywithagun says: April 12, 2012 at 16:34 Aim? What’s that? Reply I_Like_Pie says: April 12, 2012 at 17:23 ATF will not see this as lightly as we do. If anyone gets caught with an oil filter at the end of a barrel they are looking at 10 years….federal Reply Matt G. says: April 12, 2012 at 17:47 Obviously you were not paying attention. Reply I_Like_Pie says: April 12, 2012 at 23:43 Umm…yes I was Reply twency says: April 13, 2012 at 15:25 Not well enough to catch where they said it’s an NFA item registered with the BATFE and a tax stamp is required. Or to put it another way: Umm…no you weren’t. I_Like_Pie says: April 13, 2012 at 22:47 Uh…That was like the first words out of their mouth on the video. Do you not understand I was referring to some idiot at home attempting to make something like this….Basically reinforcing the idea for the third time. I feel sorry for your poor wife. HSR47 says: April 12, 2012 at 19:24 While I don’t necessarily disagree with much of your statement, it sounds like you are making an incorrect assumption, namely that there is no registered item. On the contrary: there IS a registered item, namely the adapter to which both the firearm and the oil filter mount. Thus, the actual concern is that the BATFE will make some kind of administrative ruling that effectively makes the device itself illegal, or otherwise impractical. I can think of at least two ways they can do this that fit with past rulings on silencers, but both amount to ruling that changing the filter amounts to some degree of manufacturing which requires an FFL+SOT and/or another tax stamp. Reply caffeinated says: April 12, 2012 at 19:30 Shhh…don’t give them any ideas. Right now it seems this is a great way to have one registered item and a ton of different “caliber adapters.” Reply I_Like_Pie says: April 12, 2012 at 23:45 Nope…I know what it is. Your scenario is the one that the ATF would like to implement. Bubba watching the video and deciding to do this himself is what I was pointing out. Reply I_Like_Pie says: April 12, 2012 at 23:42 And it kinda appeared only suited to .22lr Sucked with the higher pressure chambering Reply HSR47 says: April 13, 2012 at 08:33 They used a machinegun though, so reduced performance is to be expected. The reason it worked so well with .22lr seemed to be mostly due to volume, and firing bursts of full auto in an intermediate caliber totally overwhelmed its capacity. It would be interesting to see how it does for similar calibers on semi-auto only. Reply Ralph says: April 12, 2012 at 18:00 Illegal in MA with or without the Federal tax, but awesome. If it saves just one child’s hearing . . . . Reply Darren says: April 12, 2012 at 18:24 Many AKs have dodgy threading that is off-center of the barrel, which means baffle strikes are likely. Seeing as this jobby uses an oil filter without metal baffles, this would seem to be just the thing for AK users wanting a cheap and effective suppressor without having to get their barrel re-crowned and re-threaded. Of course, there is the problem of heat buildup and a fire inside the can…in which case you’ll need another oil filter. Reply Darren says: April 12, 2012 at 18:50 Heh, on the Cadiz Gun Works site they call it a “Solvent Trap” to catch the cleaning fluids coming out of the barrel when you put in a brush for cleaning from the breach. Good luck with that. Reply Ian says: April 12, 2012 at 18:38 I could be way off but I remember reading somewhere (on this site maybe) about how if you need to replace the “packing” or “baffles” or whatever it’s called inside of a suppressor and it’s not under warranty (ie, you do it yourself), that ever part you buy for the suppressor is subject to the $200 tax and regulation. If I’m recalling correctly, does this mean that with this adapter, the stockpile of oil filters you bought last time NAPA had a sale would be considered unlicensed parts? Edit: I did some googling and found this: http://www.law.cornell.edu/uscode/text/18/921 (scroll down to section 24) (24) 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. It sounds like they could indeed think that extra oil filters are suppressor parts. Reply Darren says: April 12, 2012 at 18:54 “and any part intended only for use in such assembly or fabrication.” This might get you out of the every-part thing, because the oil filter has another legitimate purpose. Since you are registering the adapter, that would be the “only for use” part. There’s not a lot of call for wipes other than for suppressors. Now if you built a frame that used, say, condoms as the replaceable wipes…could the ATF argue that a pack of Trojans is a suppressor? It would not surprise me if they did. Reply caffeinated says: April 12, 2012 at 19:12 I followed some of the discussions on the Saiga12 forums and they are in the NFA registry per the owner of the company. I think the solvent trap may have just been an attempt at humor. Reply Matt in FL says: April 12, 2012 at 19:48 I kinda want one, but I can’t stomach the idea of waiting 6+ months on a tax stamp for that thing. Reply Tom says: April 12, 2012 at 20:04 Interesting play toy. Reply Ralph says: April 12, 2012 at 21:24 Would the silencer still work if the filter was attached to the car? Reply Darren says: April 13, 2012 at 00:29 Depending on the state, $200 to register your car as a suppressor accessory with the BATFE might be cheaper than registering it with the state. Reply APBTFan says: April 13, 2012 at 00:00 So who’s gonna be the first to make Tactical Black oil filters? Preferably with skulls or that Arabic Infidel symbol. “Endorsed by SEAL Team 6” maybe, even, possibly. Reply Steve says: April 13, 2012 at 04:25 Excellent. So after I do an oil change on my car, I use re-use the filter as a suppressor. That’ll work… right?? Reply HSR47 says: April 13, 2012 at 08:39 It might. It could be more or less effective, depending on how intact the internals are when combined with the potential additional mass of accumulated sludge. It would also likely get your gun much dirtier, and contaminate the area you are shooting. Reply mike says: April 15, 2012 at 00:34 You know,,well at least in my state I can pay a fee and can leagally use supressors and automatic weapons. I forget which FFL it is, but here the average Joe, after the proper background checks and the $250.00 fee (that is annual I believe) and then registration with the Sherriff’s department you can suppress your weapons. Reply HSR47 says: April 15, 2012 at 11:31 The federal process requires a one-time payment of 200 dollars, which buys you the tax stamp that makes possession legal. The NFA is, according to the courts, a legal tax code, and it is based on taxing the transfer of certain items. Theis, the approved form 4 with stamp affixed is proof positive that the tax has been paid. Reply Todd94590 says: April 15, 2012 at 08:10 … so, 5W-30 in the summer, 10W-40 in winter? -or do I have that backward. maybe .38 in the summer and .45 in the winter…. hmm, I’m confused. If I use synthetic, can I safely run another 100 rounds through before a filter change is required? Reply speedracer5050 says: August 4, 2012 at 17:02 Go with the K&N Gold filters!!! K&N warranties all their air filters for a million miles so maybe the oil filter will last at least a few hundred!!!???? Would definitely go with new ones tho’, I don’t think the xtra lube from used ones would do much good!!!! Reply Write a Comment Cancel reply Your email address will not be published.
