Being devils advocate saint.. couldnt you then make the claim that all airsoft guns have a non-permanent muzzle velocity (as it's just the change of the spring) and that all airsoft guns can reach muzzle velocities exceeding 430fps making them a firearm by definition. ie.. you bought a car without wheels.. but you can always add them.. it's still a car isn't it? I dont think this is true.. but have no arguement for it yet.
