Depends on the gun some you can put a pin in it some you just need to get an automatic chamber for it.
...You don't.
Cost prohibitive
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.
You Can't. This Idea is beyond the capabilities of the pistol.
Call the ATF!! They can explain EXACTLY how to do it. In other words "DONT DO IT"
Automatic, What gun?
No, it is semi-automatic only.
A non-automatic gun only fires once each time the trigger is pressed.
only a class 2 firearms dealer can do this legally www.atf.gov mechanical or parts malfunction can cause this to happen
Machine gun or machinegun. All of them are automatic, so it is redundant to say that. There is no such thing as a semi automatic machine gun, or a single shot machine gun. That answer is correct, but many people use the term fully automatic machine gun or full auto machine gun to specify they are not talking about a semi-auto pistol or rifle, which are commonly referred to as autos, and sometimes that term confuses people.
