Abstract
A cleaning device for preserving a barrel of a firearm includes a central member defining a core and having a longitudinal length, a leading end and a trailing end. A tubular woven sheath surrounding the central member and has a lead end and a trailing end. A radial protrusion formed of a polymer is disposed about the central member between the central member and the sheath. A volatile corrosion inhibiter (VCI) is disposed on or in the cleaning device and configured to off-gas to cause a substantial part of an interior of the barrel to become lined with a protective coating to resist corrosion. The cleaning device is configured to be stored within the barrel of the firearm. A method for storing a cleaning device within a barrel of a firearm for preserving a barrel of a firearm is also described.
