Solvent trap oil filter adapter

[JohnKSa]

But the "consumables" of the suppressor (wadding, screens, wipes to name a few ) are not considered part of the silencer since they are manufactured for a completely different purpose they do not fall under the scrutiny of the law (unless in this case, it is attached to an unregistered adapter).

As long as you don't change the shape, length (+\- .25") and the serialized info you are not required to mess with the ATF again for that suppressor.

With the possible exception of wipes (which some sources state can be replaced by the user) the rest of your information is incorrect according to the ATF.

Here's a copy of the ATF letter.

So take it as you may.

This is incorrect; you're basically encouraging people to break the law. When you have a registered oil filter silencer adaptor, it comes with one oil filter. This filter is not considered a consumable by the ATF; they consider it a silencer part. Therefore, you can't change it out yourself. When the filter wears out, you're supposed to send the whole thing back to the manufacturer for them to switch it for you. Last I checked, most companies only charged about $25 for the switch.

Sure, most owners of oil filter silencer adapters probably change out the filter themselves without ever getting caught, but that doesn't mean it's legal.
