Hoppe"s BoreSnake is the fastest bore cleaner on the planet. One pass loosens large particles, scrubs out the remaining residue with a bronze brush, then swabs it all spotless with a cleaning area 160 times larger than a standard patch. Add a few drops of Hoppe"s No 9 Lubricating Oil or Hoppe"s Elite and your gun is ready for storage. The world"s quickest three-step bore shine. Extremely packable. Brass weight on the pull cord is stamped with the size. Machine washable. Patented one-piece design.
