thread adapters for oil filter suppressors...?

[aggie97]

So, I was at the gun show here in Bryan/College Station yesterday and there was a guy there selling these adapters with a sign that said "no ATF paperwork required". My memory thought otherwise and I didn't even bother to look closer except that the prices were cheap.

So I look up the info today and "econo-can" sells the adapters w/filter for something like $75 but very specifically says it will require a Form 4, and when you wear out an oil filter, you must send it back to them to be switched out according to the ATF to keep the serial #'s intact. Then I find more adapters on ebay for less than $20 that are just general thread adapters/bushings and ZERO mention of ATF paperwork.

The first 30 hits on a Google search this morning gave me 30 different views and navigating the ATF site is a nightmare.

Does anyone have an official or semi-official link to the true legality of these things? I might consider one for just shooting around on our new property to keep the neighbors off my butt.

Thanks,

and of course, a bit more digging with a much LONGER google search string found a law office with a decent write up....found here. https://johnpierceesq.com/suppressor...d-legal-traps/

So 2 things really:

1. How is this guy selling this stuff and NOT getting in trouble...?
2. Reading the copy of the ATF write up on this site, it says that even having spare filters that could fit a serialized adapter in your home could net you some problems. Guess I need to go through all my extra pipe parts drawers and throw out all the stuff that could potentially make one too...YIKES!

Most of the companies selling Form 1 suppressor parts seem to get away with it by stating their intended use is something other than suppressing a firearm.

I would just look at some of the more budget friendly manufactured suppressors if you are interested in keeping the neighbors happy. With how much the market has expanded you can come in below $700 with stamp for a .30 caliber model.

One of my dads friends represented a guy that was charged with having unregistered silencers by use of the oil can adaptors.

That said they all suck. You'll spend enough on oil filters to buy a real silencer since it's not going to last long at all. And it's just a gimmick for the idiots that want to be cool and feel like they're skirting the laws.

Talked to someone at work and they actually work pretty well but the round count for them is kinda low. Seems like a fun cheap way to go if you don't plan to shoot too often.

Sounds like a waste of money. Bigger waste if you get caught.

Also keep in mind most oil filters are so big your iron sites, and most optics are useless. I don't agree with nfa laws and I certainly dont like paying a tax for a "right", but I bought two legal suppressors and one sbr so far. It really isnt that difficult to buy a legal one.

The show in ft worth a guy had a huge selection of adapters he was selling. There was a sign that said something about no form required. They were basic adapter with threads in one end for a filter and threads to fit various firearms. He wanted like $75 each for them. I kept walking

Probably the same guy. Even had one with a small diameter fuel filter about 10" long that didn't block the sights. There is a novelty for being creative, however the penalty is too great for the small thrill. Hopefully if the hearing protection act goes through, production can keep up with demand for suppressors afterwards.

If you want to build your own silencer the DIY kits aren't that expensive. It's worth it to buy a warrantied can from a manufacturer though.
