Ok, but I can buy the adapter @ the gun show - until there's a hole in the oil filter, the adapter isn't a controlled part - it's a what the hell do they call it? Oh yeah, a "solvent trap."
I'm not trying to do anything illegal here, I'm just trying to understand why if you do the Form 1, aren't you the manufacturer? So when the crappy oil filter wears out, you torch cut it into 4 pieces, then go down to the auto parts store & buy a new one. I'm missing something, or everyone would be doing this. What is that something?
Is it another $200 to engrave a new oil filter? Even if we put it inside a fixed length can? Is it only SOTs can repair suppressors & replace baffles? But if you manufactured your own suppressor, and a baffle breaks, surely you can open up the can, remove the broken baffle, torch cut it into 4 parts, make a new baffle, & repair your own suppressor, right? So why can't I replace the oil filter inside my can?
I understand no one is doing this b/c we think it's illegal. What I'm not understanding is WHY it's illegal. Is there a BATFE Tech Branch letter that forbids oil filter suppressors? No, b/c there's someone selling tax stamped engraved ones. So why can't we do this?
