ABSTRACT:
The present gun barrel cleaning device provides a special cartridge with a casing filled with a carbon dioxide charge which forwardly propels a push pin having a sliding seal near the firing pin and a two-pieced break-away seal at the opposite end, which separates to push a cloth rag and metal brush through the bore when the cartridge is loaded into the gun and the gun is fired.
