You Can't. This Idea is beyond the capabilities of the pistol.
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.
if it fires more than one round (or BB ect.) it is not. By definition semi-automatic means it will fire with each pull of the trigger.
The IZH Drozd is a full auto BB gun.
yes
The Crosman r34 is not automatic or semi-automatic. You have to manually reset the action for every bb you shoot.
No
Yes, you can ship semi automatic bb guns to new zealand but not fully automatic ones
You can't ! They're illegal !
Yes. In years past these automatic BB machineguns operated off compressed air which is how they were able to operate in an automatic way. Have not seen such auto BB guns in many a year........
it all depends on the make and model. You did not say what kind of BB gun.
No it is a single spring powerd fire
