...You don't.
Depends on the gun some you can put a pin in it some you just need to get an automatic chamber for it.
Guns can't be made in Minecraft without modding.
Without using mods, you can't.
Cost prohibitive
You cannot, without mods.

Its helps build a house? P.S i lov the game :)
this automatic gun looks like..........your face! why would you ask me????????
In the truest sense of the definition of "automatic", no a bb gun cannot be automatic. In function, however, a BB gun can be automatic. A good example would be the Drozd BB gun which fires full automatic, but used CO2 as the power source.
In a semi automatic gun you have to pull the trigger for each shot. In an automatic gun you just have to hold the trigger in to empty the clip.
Tornadoguns are not part of normal (vanilla) Minecraft part are part of a mod.For the craftingrecipeyou should refer to where you downloaded the mod from.
