 treatment, a YAG laser which produces infrared radiation is used for purposes of treatment, and simultaneously, a He-Ne laser or the like which produces radiation in the visible portion of the spectrum is used to provide guide light for safety purpose since the output radiation from the YAG laser is invisible. Hence, it will be seen that the mere provision of the infrared rejection filter disposed in front of the solid-state camera mounted within the distal end of the endoscope is inadequate for preventing the smearing effect when a CCD camera of LT type is employed. A variety of guns for firing frangible, generally spherical projectiles are known in the art. Marking guns, (commonly referred to as paint ball guns) for example, use pressure from compressed gas, such as nitrogen or carbon dioxide, to fire a gelatinous capsule containing a marking material (usually paint). The capsule breaks on impact with a target dispersing the material thereby marking the target. A popular recreational use for marking guns is in “survival games,” a kind of mock war where opposing sides attempt to seek out and “shoot” one another with paint balls. Paint ball guns have also been used to segregate cattle within a herd and for a variety of other marking purposes.
Paint balls fired from such guns may have a limited trajectory because of the flight characteristics imposed on them by the amount of force that can be applied and by the configuration of the bore. In some applications, restrictions may exist on the velocity with which the ball may be expelled from the barrel. Consequently, there is a need for a gun that can affect the trajectory of the paint ball by changing its flight characteristics through changes in the gun bore, rather than by increases in force applied to the ball.
It is important to note that paint balls are relatively frangible. It is, therefore, necessary that the structure or method used to improve the trajectory of the paint ball does not cause premature rupture of the ball.
Accordingly, an illustrative embodiment of the present invention provides a gun of the type configured to fire a paint ball. The gun comprising a firing mechanism and a barrel. The firing mechanism defines a first plane. The barrel has a breech end coupled to the firing mechanism for receiving the paint ball, a muzzle end, and a bore having a length which extends longitudinally between said breech and muzzle ends. The length of the bore between the breech and muzzle ends is curved so as to impart a spin to the paint ball as it travels through the bore. A second plane
treatment, a YAG laser which produces infrared radiation is used for determination of discussion, and simultaneously, a He - Ne laser or the like which produces radiation in the visible parcel of the spectrum is use to provide guide lighter for base hit purpose since the output radiation from the YAG laser is invisible. therefore, it will be seen that the mere provision of the infrared rejection filter disposed in presence of the solid - state camera mounted within the distal end of the endoscope is inadequate for prevent the smearing effect when a CCD camera of LT character is employed. A variety of grease-gun for firing frangible, by and large spherical projectiles are known in the art. Marking gun, (commonly referred to as paint ball guns) for example, use pressure from compressed gas, such as nitrogen or carbon dioxide, to fire a gelatinous capsule containing a marking material (usually key). The capsule breaks on shock with a prey dispersing the material thereby marking the prey. A popular recreational use for marking gun is in “ survival games, ” a kind of mock war where opposing sides attempt to seek out and “ shoot ” one another with rouge balls. Paint ball guns have besides been used to segregate cattle within a ruck and for a variety of other marking purposes. 
 Paint balls fired from such gun may have a limited trajectory because of the flight characteristic imposed on them by the amount of force that can be applied and by the shape of the bore. In some applications, restrictions may exist on the velocity with which the ball may be expel from the barrel. Consequently, there is a motivation for a gun that can involve the trajectory of the paint testis by changing its flight characteristics through changes in the gun tidal bore, rather than by increases in force apply to the ball. 
 It is important to note that paint balls are relatively frangible. It is, consequently, necessary that the structure or method practice to improve the trajectory of the paint ball does not cause premature rupture of the ball. 
 Accordingly, an demonstrative embodiment of the present invention provides a gun of the type configured to fire a key musket ball. The accelerator comprising a firing mechanism and a barrel.
