An improved paint gun barrel for use in conjunction with available paintball maker guns that fire thin-skinned ball with contents varying from paint to pepper compounds. This improved barrel assembly features three major improvements. The first uses of a non-floating bore bushing that is manufactured using precision and tight tolerances, which provide alignment and consistency. The second is the use of chamfers to center and align the firing path of the gun. These chamfers force said bore bushing against and center it to the breech face of the marker gun while aligning the firing path by centering the muzzle-end subassembly to said bushing. The thin-skinned ball is projected, by a force of gas, down a tightly fitted bushing. This bushing is held in suspension rigidly by the compression between the maker gun itself, and the subassembly members. This compression combined with the use of chamfers force a consistent, rigid and perfect alignment along the paintball's firing path. The third is a method of selecting the bore bushing for proper size and fit given factors of temperature, humidity and the paintballs available to the end user. The combination of these improvements increases the firing distance and accuracy while reducing the exposure to paintball ruptures within the system. Such a combination has not been achieved prior to this invention.
