Abstract
A lacquer bullet gun barrel, having a barrel case, concentrically surrounding a boring and having a rear end that is fastened to a front end of a gun case. The rear end of the barrel case has a cavity, receiving an insertion tube, which has a diameter equal to said boring and is aligned with said boring on a common axis. With this assembly, lacquer bullets tightly fit into the insertion tube, so that gas drives lacquer bullets therein with high pressure. Aligning the insertion tube with the boring ensures firing precision and an increased firing range.
