While technically your correct, it all comes back to "grey" areas, in particular power output.
Like most things it usually takes a legal precedent for the government to take action in implementing or altering laws.
For us it's unlikely to be on the basis of power output, most of the gats we use would implode if we tried to get them up to near lethal output levels.
The only other real issue that could affect us in the future is the realism of the kit we use, & again there'd have to be a precedent set in order to trigger a government response, either a massive increase in the number of specifically airsoft rifs in crimes, in particular violent crimes or crimes against the establishment, bank robberies etc,
Or an increase in cop versus airsoft rif fatal shootings, in which case coroners & the like call for further restrictions against their availability.
The similarities between our kit & air weapons is primarily mechanical, pistons displacing air etc, but it is ridiculous that it's much easier to purchase a much higher power air rifle or pistol, that can also be as realistic as real steel, than it is our pot metal & plastic low power toys.
I for one don't feel there's any benefit in publicly admitting that on paper we technically are the same, because if "they" go after them, they might tar us with the same proverbial brush.
But that's only my opinion. ?
