Singular Modular Barrel Assembly

Abstract

A singular modular barrel assembly allows a projectile weapon to fire both tubular arrow type projectiles and internal bullet type projectiles. The singular modular barrel assembly includes components that can be attached or detached from the singular modular barrel assembly, thereby, altering the barrel configuration in order to allow the projectile weapon to fire either tubular arrow type projectiles or internal bullet type projectiles. The singular modular barrel assembly includes an outer tube, an inner tube, and a barrel-attachment body. The outer tube is a barrel shroud that protects and aligns the inner tube. The inner tube allows a tubular arrow type projectile to be loaded or allows passage for an internal bullet type projectile. The barrel-attachment body allows the singular modular barrel assembly to be attached onto the existing barrel of a projectile weapon. The singular modular barrel assembly can be used with either pyrotechnic or pneumatic projectile weapons.

         5 . The singular modular barrel assembly as claimed in  claim 1  comprises:
 a plurality of inner grooves; 
 the plurality of inner grooves being integrated into an inner lateral surface of the inner tube; and 
 the plurality of inner grooves being distributed around a central axis of the inner tube. 
 
     
     
         6 . The singular modular barrel assembly as claimed in  claim 5  comprises:
 the plurality of inner grooves being arranged into a helical configuration about the central axis of the inner tube. 
 
     
     
         7 . The singular modular barrel assembly as claimed in  claim 1  comprises:
 a barrel-supporting tube; 
 a compressing mechanism; 
 the barrel-supporting tube being attached into the distal open end of the outer tube; 
 the barrel-supporting tube being concentrically positioned within the outer tube; 
 the distal open end of the inner tube traversing into the barrel-supporting tube; and 
 the inner tube being mounted into the barrel-supporting tube by the compressing mechanism. 
 
     
     
         8 . The singular modular barrel assembly as claimed in  claim 7  comprises:
 a plurality of vents; 
 the plurality of vents traversing through the barrel-supporting tube; and

         9 . The singular modular barrel assembly as claimed in  claim 7  comprises:
 the compressing mechanism comprises at least one first O-ring; 
 the at least one first O-ring being laterally positioned around the inner tube; and 
 the at least one first O-ring being pressed in between the inner tube and the barrel-supporting tube. 
 
     
     
         10 . The singular modular barrel assembly as claimed in  claim 7  comprises:
 the compressing mechanism comprises at least one second O-ring; 
 the at least one second O-ring being laterally positioned around the barrel-supporting tube; and 
 the at least one second O-ring being pressed in between the barrel-supporting tube and the outer tube. 
 
     
     
         11 . The singular modular barrel assembly as claimed in  claim 7  comprises:
