1. A gun for firing projectiles using fluid pressure, comprising;

  • a barrel;

    a magazine for containing a plurality of projectiles and introducing said projectiles one at a time into said barrel into a firing position;

    a bolt reciprocal in said barrel between a rearward position in which the bolt allows a said projectile to be deposited into said firing position, and a forward position in which said bolt blocks projectiles from entering said barrel from said magazine, said bolt including a through aperture to allow passage of compressed gas;

    means for reciprocating said bolt;

    a compressed gas source connectable to said barrel to fire a said projectile;

    electronic control means for controlling said gun;

    an electrically controlled valve means for controlling passage of gas from said source to said barrel;

    electronic means to detect presence of a said projectile in said firing position and send a projectile presence signal to said electronic control means;

    electronic means to detect whether said bolt is in said rearward or forward position and send a bolt position signal to said electronic control means;

    a user actuatable trigger for sending an actuation signal to said electronic control means,whereby, when said electronic control means detects that said projectile is in said firing position and said bolt is in said rearward position, and said electronic control means receives an actuation signal from said trigger, said electronic control means will send a signal to said bolt reciprocating means to move said bolt to said forward position,and then when said electronic control means detects that said bolt is in said forward position, said electronic control means will send a signal to said valve to release gas into said barrel to fire a said projectile.
