The Hoppe's Boresnake® Viper takes the technology of the original Boresnake® and increases the cleaning power by adding an additional set of brushes. This one-pass bore cleaning solution uses integrated bronze brushes to scrub out carbon fouling, while the tail clears the barrel of loose debris with a surface area 160x larger than a standard patch. It also has an integrated cone-shaped bore guide on the leading end and the brass weight has the caliber stamped on it. Just add Hoppe's No. 9 Cleaner and Oil or Boresnake® CLP to the head and tail of the Boresnake® and run it through your rifle bore for a quick clean.
