“Why the lie about all 50 states?”

If reading the article correctly, the SiCo device falls outside the NFA (feral law, not state) definition of a “silencer.” Mainly because it is integral with a non firearm, also as defined by the NFA. Gamo sells a line of spring-action air rifles with integral suppressors/silencers (necessary only for the first 1000 shots until the dieseling stops).

Add on suppresors (we call them lead dust collectors) are popular with the pre-charged pneumatic pellet rifles and pistols.

They do not do much for spring guns I found.

I have a Gamo Whispercat in .177 that has an integral suppressor, and the suppressor really, really sucks.

I wouldn’t even term it a suppressor. It’s just a bulbous termination of the barrel.
