oil filter silencer BATFE registered

[soundguy]

i see articles as far back as 2008 for SWR Spectre Multi Caliber Suppressor, and looks like in 2009 these people make 2 supressors that are listed as suitable for multi caliber use, and include take down tools..e tc.. etc..

Exactly. The BATFE has relaxed a lot on suppressors. used to be they had to be welded shut, no cleaning, no replacing baffling material, and on and on. Now it has become a more open field per say. the idea of a multi caliber suppressor appeals to many. Most cannot afford $200 for each caliber they want so it was only logicial to go to a multicaliber. As a buddy whom is a class III dealer stated, the BATFE has gotten so if you can put numbers permently on a PVC pipe, form 1 it, form 4 it, and pay the $200; then they could approve it! The adapter for the oil filter is another example. You are paying $200 tax for an adapter, not the oil filter being it is replacable. Now if they are allowing an adapter as a NFA decise, then they have relaxed a whole lot on regulation as to supressors.

When they say it is for multi caliber use, it means in this case the bore is large enough for the 9mm, strong enough for the 300 blackout and can be taken to clean after using with dirty cartridges like the 22lr. Nowhere in that link does it say they have multiple sets of baffles.

This can is wide enough to cover the sights on many 22lr pistols and some 9mm pistols. I'm sure it works very well as far as suppression goes as it has lots more volume than the typical 22lr silencer and nearly as much as some 30 caliber silencers.

The silencer in your link is a good choice for a person who is on a budget and does not need the peak performance expected from a silencer dedicated to a specific cartridge. I have seen 9mm cans used on 22lr guns, they worked nearly as well and were perfectly acceptable as long as the gun used was not something small like the P-22. But on scoped pistols and rifles they are good enough.

I have never read any federal law, rule or regulation that prohibited take apart silencers registered on one tax stamp. As far as I know the BATFE is getting stricter as time goes by, not more lenient. If anyone has a link to any recent (in the last 10 years) law or ruling that makes things easier for us, please post it.

The BATFE has always been willing to register anything as a silencer no matter what it was made of. As long as the forms will filled out correctly they would approve them. No form 1 builder should have ever been required to send in plans or specifications other than the caliber and length listed in blcok form of the ATF form 1. The length block was usually filled in as "not applicable" by many form 1 builders until the BATFE started telling us to specify a length.

seems like a new wipe is all that is needed to make it truly multi caliber..

[883n]

A new wipe would do this. But I would never use a wipe silencer on a firearm that was expected to hit a small target more than 25 yards away. Most people using 22lr and 300 blk rifles want to be able to hit targets at 100-200 yards away.

in Ct. you have to apply to get a silencer i think it is 200 or 300

Federal law states that anyone who makes, buys or sells a silencer has to pay a $200 tax to the US Treasury prior to doing so unless they are licensed to do it as a business (FFL/SOT), transfer to the government, police or a museum on an ATF form 5, inherit on an ATF form 5 or make it for a government agency.

CT law actually states in part;

Sec. 53a-211. Possession of a sawed-off shotgun or silencer: Class D felony. (a) A person is guilty of possession of a sawed-off shotgun or a silencer when he owns, controls or possesses any sawed-off shotgun that has a barrel of less than eighteen inches or an overall length of less than twenty-six inches or when he owns, controls or possesses any silencer designed to muffle the noise of a firearm during discharge.

(b) The provisions of this section shall not apply to persons, firms, corporations or museums licensed or otherwise permitted by federal or state law to possess, control or own sawed-off shotguns or silencers.

(c) Possession of a sawed-off shotgun or a silencer is a class D felony.

CT does not require the payment of any other fee to transfer or make a silencer.

What you just said - "Federal law states that anyone who makes, buys or sells a silencer has to pay a $200 tax" - is wrong. If I make one, then I have to pay a tax. If I buy one, then I have to pay a tax. But I don't pay a tax for selling one. If your statement was true, there would be 400 dollars in taxes on every transfer - the 200 I pay to buy it and the 200 you pay to sell it. One 200 dollars tax on the transfer. Government don't care who pays it - the buyer or the seller - but there is just one 200 dollar tax.

[883n]

Opps, I mis-typed. It would have been better to say transfers instead of buy/sell. Thanks.

The law says;

Part II – Tax on Transferring Firearms.
§ 5811 Transfer tax.
(a) Rate. There shall be levied, collected, and paid on firearms transferred a tax at the rate of $200 for each firearm transferred, except, the transfer tax on any firearm classified as any other weapon under section 5845(e) shall be at the rate of $5 for each such firearm transferred.
(b) By whom paid. The tax imposed by subsection (a) of this section shall be paid by the transferor.

The law says that the seller pays the tax, but I am told that the dealers normally have the buyers write the check so they can send it in with the application.

I guess I am better off quoting the law instead of trying to remember what it says.

depends on what you consider small.

I've used an extremely inacurate sub-bullet hose with a wipe type and can hit 8.5x11 paper targets at 50yds in sa mode... using SS ammo no less...

as stated in another thread. most accuracy issues aside from a errant foul ball thrower, is the result of the person pulling the trigger...

The funny part about this post is I'm the one who shot that video. I'm Eric with ASA "American specialty ammo" and that is our econo can suppressor. Works great just don't use it in an AR-15. We found out that they suck air and draw the material in the suppressor(oil can) back into the gun. It's works much better on an AK platform. We have even run a .308 with one on it but the oil can doesn't last very long with the .308.

[883n]

How does that setup affect accuracy? Does adding water or oil to the filter reduce noise like any other can shot wet? What is the life of the filter? Have you been able to shoot it by an appropriate noise meter to see how effective it is? Thanks.

[soundguy]

that'd be neat.. use a Db meter to test it! sounds like something up my alley!

[883n]

A cheap noise meter and microphone do not do a good job of accurately determining levels from short duration noises like gun shots. A meter/microphone combo needs to have no more than a 20 micro-second response time according to the experts. Otherwise you end up getting low levels like 80 to 100 decibels when is it obviously louder than that. This kind of setup is about $4000 and up.

i work around hundreds of thousands of dollars of pro audio gear for work purposes.. including real time anylizers, reference quality mics and nois gens and signal db meters with graphing and computer store capability.

it's no big deal. you can't use a 30$ analog swinging needle job, or the app on an iphone.. but there are plenty of ways to do it right.. especially with a meter tha has different weightings and speed sampling rates.

I've been told It will affect accuracy at range but within 100 yards (.223) you should be fine and if your shooting subsonic that's about all you would be doing anyway. It's really only the first shot that is affected all that much and that's just because it's punching threw the oil can. From what I've seen it doesn't do much to the accuracy.

I wouldn't recommend shooting it wet just because the martial in the filter will absorb the water and I have no idea what that would do besides make it heavy. We actually have never tested that.

The life of the filter depends on what you are shooting out of it. With a .22lr you can shoot it all day. With a .223 you might get a hundred shots out of it but It's made and sold to be used with a .22lr. Having said that we beat the heck out of them. We have put on on an RPD before. it only survived one belt of 7.62 but it worked good. We also run them on our full auto guns but I don't recommend it. We just do it because we can and we get bored at the range.

i reckon the things great ..

i had a full Sionics kit done on a Mac , that was $3000 back then ( 82?)

and they had to be emptied and repacked every 500 rounds , but make it 300 and you wont get a surprise when its starts to roar ...

or this, a few bills for the unit , $9 a can , for 50 rounds of .223 or a heap of .22 lr

just as a can this is way cheaper and way shorter than most cans i say hats off to whoever invented it

That would be Tom coal with cadiz gun works. He is a darn good gunsmith and Chris Reed owner of ASA works with him a lot. We sell his Adapters but he is the one who makes them.

[Grizz]

do your adapters thread onto all oil filters or only certain ones?

[jack404]

had a thought about site picture though

problem sorted



2/3's the diameter so only 3" wide ( 1 1/2" from center bore)

1 1/2 times the length

now to get the things legal here ..

[cpttango30]

I think Cat or cummins, or detroit make a skinny fuel filter. that is a lot less that most oil filters. I don't remember it has been 15 years since I changed the oil on a big rig.

[soundguy]

there are quite a few narrow filters to choose from/ I have a small fleet of heavy equipment I service. some filters are just a bit larger around than a toilet paper cardboard inner sleeve..
