Presumably legal. There are no solid statistics to indicate what the number of illegal guns are - it can only be estimated. Also, there are very few guns that are illegal. This would include only machine guns and destructive devices without proper paperwork.

Felons may not possess guns, but it is the felon status that makes this a crime, not the gun.
There is no licencing anywhere for airsoft guns.
It is only illegal if you kill or injure the deer when it's not in season and/or without the proper tags and licence. Most potato guns have the potential to injure a deer, and if it does, you may receive a nasty fine from the game warden. It is not illegal if the deer remains unharmed however.
there are legal weapons, most require a permit or licence to own or purchase, eg: guns require a firearms licence, I'm not sure if stun guns or tassers are legal, even with a permit or licence, you can purchase swords with a weapons permit, but there strictly for display to carry them around on the streets, or in your car would be illegal, knives and machetes are legal to purchase, but when transporting them they have to be stored correctly.
Depending on where you are, guns are NOT illegal.
