Abstract:
1. A device for cleaning the 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; and 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, and wherein the tubular woven sheath is held in place by a tight fit of the tubular woven sheath over the radial protrusions.
