Hoppe's Boresnake bore cleaner, for 9 mm/38/357 Pistol or .22 Rifle. Hoppe's Boresnake is the fastest bore cleaner on the planet. One pass loosens large particles, scrubs out the remaining residue with attached bronze brush, then swabs it all spotless with a cleaning area 160x larger than a standard patch. Add a few drops of Hoppe's No. 9 Lubricating Oil or Hoppe's Elite Gun Oil and your gun's ready for storage.
