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.

1. A cleaning device for preserving a barrel of a firearm having rifling lands comprising: a central member defining a core and having a longitudinal length, a leading end and a trailing end;a tubular woven sheath surrounding said central member and having a lead end and a trailing end;at least five annular thermoplastic elastomer features disposed around said central member and spaced apart along the longitudinal length of the central member such that each feature is adjacent to another of said features, each of said features comprising at least one radial protrusion helically oriented around said central member, all of said radial protrusions having a same helical direction and substantially a same helix angle, and the radial protrusions of adjacent features being disposed in a progressive angular rotation relative to the central member such that said radial protrusions collectively form at least one discontinuous helix having discontinuities defined by a longitudinal space between each pair of adjacent features, wherein the radial protrusions of successive features urge a plurality of overlying fibers of said tubular woven sheath to engage and follow the rifling lands of an inner surface of said barrel of said firearm, wherein said features are disposed separately along said central member between said central member and said tubular woven sheath, and wherein the tubular woven sheath is held in place by a tight fit of the tubular woven sheath over the radial protrusionsa first area of thermoplastic elastomer or absorbent material disposed about said central member at about said leading end, and a second area of thermoplastic elastomer or absorbent material disposed about said central member at about said trailing end spaced apart by about the length of said barrel of a firearm, said at least five annular thermoplastic elastomer features disposed along said central member between said first area of thermoplastic elastomer or absorbent material and said second area of thermoplastic elastomer or absorbent material, said first area of thermoplastic elastomer or absorbent material and said second area of thermoplastic elastomer or absorbent material being separate structures not a part of any of said at least five annular thermoplastic elastomer features;a volatile corrosion inhibiter (VCI) disposed between said leading end and said trailing end and configured to off-gas to cause a substantial part of an interior of said barrel to become lined with a protective coating to resist corrosion; andwherein said cleaning device is configured to be stored within said barrel of said firearm and said first area of thermoplastic elastomer or absorbent material and said second area of thermoplastic elastomer or absorbent material fit tightly within said barrel of said firearm to retain said VCI within said barrel of said firearm during a storage period. 2. The device of claim 1, wherein said VCI is molded or extruded within at least a portion of said sheath. 3. The device of claim 2, wherein said VCI is molded or extruded within at least a portion of one or more fibers of said sheath. 4. The device of claim 1, wherein said VCI is molded or extruded within at least a portion of a plastic protective coating of said central member. 5. The device of claim 1, further comprising an overmolded thermoplastic elastomer area between said leading end and said trailing end, wherein said VCI is molded or extruded within at least a portion of said overmolded thermoplastic elastomer area. 6. The device of claim 1, further comprising an absorbent area between said leading end and said trailing end, wherein said VCI is molded or extruded within at least a portion of said absorbent area between said leading end and said trailing end. 7. The device of claim 1 wherein said sheath comprises an abrasive selected from the group consisting of nylon, polystyrene, acetals, acrylics, and brass. 8. The device of claim 1 wherein said sheath comprises heat resistant materials selected from the group consisting of meta-aramids, NOMEX, para-aramids, KEVLAR, fiberglass, and K-fiber. 9. The device of claim 1 wherein said sheath includes a fiber selected from the group consisting of fiber-optic, luminescent and phosphorescent configured to provide for auxiliary lighting for visual inspection of said barrel. 10. The device of claim 1, wherein said first area of elastomer or absorbent material and said second area of elastomer or absorbent material are between the central member and the sheath.
