Even if what you alluded to was true (which it isn't), if you commit an offence with an airgun you are prosecuted under a firearms offence. That's because airguns, under the act, are firearms.
Some don't require a license because they fall outside of a section of the act, others do, because the are explicitly described as such. An example is a Brockock, which is under 6ft-lb but described in Section 5 as using a self contained cartridge. A semi auto is also described.
