Paint ball gun with compression zone liner

Abstract

A paint ball gun having a breach, a compression zone and a gun barrel. The breach, the compression zone and the gun barrel cooperate to form a continuous, smooth path for the pneumatic ejection of paint balls from the paint ball gun. The compression zone comprises a bore in communication with the breach portion and a removable tubular liner disposed within the bore. The liner is readily interchangeable with other liners of slightly differing internal diameter to allow the user to match the diameter of the compression zone with the diameter of the user's paint ball ammunition.

What is claimed is:  
     
         1 . A pneumatic paint ball gun comprising: 
 (a) a gun body having a nose portion and a breach portion, the nose portion having a linear bore which communicates with the breach portion;    (b) a hollow, elongated gun barrel removably attached to the nose portion, the gun barrel being disposed coaxially with the linear bore; and    (c) a removable, tubular liner disposed within the linear bore such that the breach, the liner and the gun barrel cooperate to form a smooth and continuous path for the pneumatic ejection of a paint ball from the paint ball gun.    
     
     
         2 . A pneumatic paint ball gun kit comprising: 
 (a) a gun body having a nose portion and a breach portion, the nose portion having a linear bore which communicates with the breach portion, the linear bore having an internal diameter;    (b) a hollow, elongated gun barrel which is attachable to the nose portion in such a way that the gun barrel is disposed coaxially with the linear bore; and    (c) at least one tubular liner having an inside diameter and an outside diameter, the outside diameter of the at least one tubular liner being slightly less than the inside diameter of the linear bore such that the at least one tubular liner can nest within the linear bore;    wherein the at least one tubular liner can be disposed within the linear bore and the gun barrel can be attached to the nose portion in such a way that the breach, the at least one tubular liner and the gun barrel cooperate to form a smooth and continuous path for the pneumatic ejection of a paint ball from the paint ball gun.    
     
     
         3 . The pneumatic paint ball gun kit of  claim 2  wherein the at least one tubular liner comprises a plurality of tubular liners, each having a different inside diameter.  
     
     
         4 . A method for using a pneumatic paint ball comprising the steps of: 
 (a) selecting a paint ball gun combination having: 
 (i) a gun body with a nose portion and a breach portion, the nose portion having a linear bore which communicates with the breach portion;  
 (ii) a hollow, elongated gun barrel removably attached to the nose portion, the gun barrel being disposed coaxially with the linear bore;  
 (iii) a first removable, tubular liner nested within the linear bore such that the breach, the first liner and the gun barrel cooperate to form a smooth and continuous path for the pneumatic ejection of a paint ball from the paint ball gun, the first liner having a first inside diameter;  
 (iv) a second tubular liner sized and dimensioned to nest within the liner bore in such a way that the breach, the second liner and the gun barrel cooperate to form a smooth and continuous path for the pneumatic ejection of a paint ball from the paint ball gun, the second liner having an inside diameter different from the inside diameter of the first liner;  
   (b) selecting a plurality of paint balls for use as ammunition in the paint ball gun, each of the paint balls having an external diameter;    (c) selecting either the first liner or the second liner for use in the gun based upon the external diameter of the paint balls, such selection being accomplished by either retaining the first liner within the gun or replacing the first liner with the second liner; and    (d) pneumatically ejecting paint balls selected in step (b) from the breach portion, through the liner and selected in step (c) and out the gun barrel.    
     
     
         5 . A method for using a pneumatic paint ball comprising the steps of: 
 (a) selecting a paint ball gun combination having: 
 (i) a gun body with a nose portion and a breach portion, the nose portion having a linear bore which communicates with the breach portion;  
 (ii) a hollow, elongated gun barrel removably attached to the nose portion, the gun barrel being disposed coaxially with the linear bore;  
 (iii) a first removable, tubular liner sized and dimensioned to nest within the linear bore in such a way that the breach, the first liner and the gun barrel can cooperate to form a smooth and continuous path for the pneumatic ejection of a paint ball from the paint ball gun, the first liner having a first inside diameter;  
 (iv) a second tubular liner sized and dimensioned to nest within the liner bore in such a way that the breach, the second liner and the gun barrel can cooperate to form a smooth and continuous path for the pneumatic ejection of a paint ball from the paint ball gun, the second liner having an inside diameter different from the inside diameter of the first liner;  
   (b) selecting a plurality of paint balls for use as ammunition in the paint ball gun, each of the paint balls having an external diameter;    (c) selecting either the first liner or the second liner for use in the gun based upon the external diameter of the paint balls, by either retaining the first liner within the gun or replacing the first liner with the second liner;    (d) disposing the liner chosen in step (c) in the linear bore; and    (e) pneumatically ejecting paint balls selected in step (b) from the breach portion, through the liner and selected in step (c) and out the gun barrel.
