What constitutes a silencer?

[wireless]

Not entirely true. The above combination of parts can be legally owned as long as it isn't intended to be used as a silencer... they are sold as "solvent traps" to "aid in cleaning" your gun.

General wisdom states that as long as holes haven't been drilled in what would be the baffles and end cap, it isn't a silencer.

General wisdom also suggests having an approved form 1 in hand before owning the non-silencer with the intention of creating a silencer.

Right...literally what I just said except you quoted a different line and responded to my part about an oil filter. The oil filter referred to before is not the same as a solvent trap kit. You can purchase a mounting device, place it on an oil filter can, and use it as a suppressor. Owning the mounting device itself does not constitute a suppressor, but adding it to an oil can creates a working suppressor.

Cadiz still sells them:

We have two in our safe. One for .22 and the other for 7.62x39. The 7.62 lasted for only 25 rounds before the filter came apart internally. It did do a good job of suppression until it failed. The .22 unit is still unfired. More of a curiosity than something really useful. The fact that the serial number is written on the filter housing with a sharpie raised eyebrows during one ATF audit! I don't know how Cadiz got that approved..

Those are the guys I was thinking of. Weird they have to be sent back for the filter change. Maybe that is the new thing I was thinking of. That stinks. 300-500 AR rounds (or only 25 AK rounds!?) What happens if they go out of business I wonder.

I think they are being very optimistic on the estimated round count for 5.56!

Again, that is not the case. Until you put a hole in (or intend to) the business end of the oil filter, the entire assembly is not a silencer. Until that point it does not meet the definition of a silencer:

In the above mentioned state (adapter with an intact oil filter attached) neither part is intended only for use as a silencer, and the assembly has yet to be "designed or redesigned" nor intended for use as a silencer.

Feds consider the tube the silencer. Even without endcaps or baffles. It is the serialized part on NFA silencers. Feds did allow some thread adapters (for oil filters) to be serialzed as NFA silencers but I think they stopped that now. CA law probably adds some nuance to the basic fed law.

So if you have mag lite body and a thread adapter and endcap, look out - possible constructive possession territory.

There is no legal requirement on which part of the silencer must be serialized. Commercial examples include the SilencerCo Osprey in which the blast chamber has all of the required markings, and is separate from the tube itself.



Many Form 1 builders engrave the cap that attaches to the muzzle.
