Straight to the point: I know that it is possible to import airsoft rifles/pistols who fire within a certain FPS limit, however, how would regulations work in regards to a grenade launcher? Would it be measured by the FPS of the fired pellets, or are there other specifics at play? I'm assuming importation of 40 mm rounds is still prohibited.
Under-barrel grenade launcher at question is a Dboys GP-25 from HK.
Appreciate any feedback!
