ABSTRACT:
A cleaning device for firearms having a firing pin and a barrel with a shell chamber, in which a casing contains several barrel cleaning layers consisting of an abrasive, solvent, wiper and lubricant layers. A propellant is disposed in the casing in close proximity to the firing pin which activates the propellant to propel the cleaning layers through the barrel. The propellant may be a cartridge containing CO.sub.2, having a neck and cap in close proximity to the firing pin which strikes and ruptures the cap to release the CO.sub.2 and drive the cleaning layers through the barrel. A soft fabric may be disposed around the cartridge, and may be impregnated with lubricant for treating the barrel after the cleaning layers have passed therethrough.
