something occurred to me, and a few of you guys aren't going to like this but ATF may be right on this. If all someone is doing is taking a solvent trap and changing it's application to use as a suppressor, that is not manufacturing, and filing a form 1 would be making a false representation to the fed gov't.
That logic is kindof flawed though.
A solvent trap isn't typically (and shouldn't be) drilled for a projectile. Machining is required.
If having a tube, with any kind of internal threading is verboten, then every store that sells's maglite flashlights is illegally selling silencers.
Manufacturer code FMI shouldn't care if you're drilling out solvent trap cups, steel condiment ramekins from Applebees, radiator freeze plugs etc. The end result would be no different than making baffles from round stock on the lathe. You took something that wasn't a baffle, and made it into a baffle.
A number of years ago, an individual from Argentina, (where suppressors are not regulated), was offering B&T IMPUL IIA silencers thru the mail for something like $1250. In switzerland and i'm sure in argentina, the B&T cans were not engraved. An idiot in San Francisco (iirc) was caught receiving one thru the mail. I don't care how "honest" his intentions might have been, ie that he intended to register it on a Form 1 etc, he did not manufacture that can.
Apples and oranges.
One is actually a silencer. The other, resembles a silencer but isn't.
Registering a device does not constitute manufacturing it, period. As much as i hate to say it, i have to agree with ATF on screening solvent traps. What i question is how are you supposed to provide pictures of the device's parts when it would be illegal to possess those prior to receiving an approved Form 1. Maybe the blueprints
You are not taking a title-1 firearm and adding it to the registry.
You are not taking possession of a registered, pre-existing NFA item
You are paying $200 and asking for permission to make something. There have been car oil filters registered as silencers. Simple male/female thread adapters have been registered as NFA items. Nobody "made these" from scratch.
If you are applying to manufacture a short barreled rifle, should you have to be able to hammer forge a blank, chamber it, button cut rifling and install it? Can't use a store bought short barrel?
By your logic every AK built on a tapco flat and registered as an SBR (FMI) wasn't really manufactured.
Every 80% lower drilled and milled out, ditto.
Every HK flat bent and welded, since the person didn't actually stamp the sheet metal on dies himself.
It shouldn't matter, shouldn't matter one bit.
You took something that wasn't a gun, and made it into a gun....that would be manufacturing. Same thing with silencers. You can still buy solvent traps today, because they're not illegal. That would take an act of congress,
This is why the ATF lost the bumpstock ban... didn't hold up in court. The ATF doesn't make law. They just recently decided to interpret in a different way than they did years ago, maybe political pressure, not sure. But the only way this actually sticks is if Congress changes the laws.
Flashlights, car exhaust, radiator freeze plugs, or solvent traps (so long as they are not predrilled, etc) are completely legal.
The ONLY argument that I could see actually "sticking" would be the following;
A part of a silencer is a silencer.
That has been pretty well covered for awhile now. It would not surprise me at all if at some point they decide they want a seperate F1 for every single component of the F1 can.
IE,
$200 stamp for tube
$200 stamp for end caps
$200 stamp per baffle, etc
