The Hoppe’s BoreSnake Viper Den is a compact, one-pass cleaning solution designed for .40 and .41 caliber pistols (also listed for 10MM fit). It combines an integrated bronze brush with a wide cleaning tail to remove fouling and clear loose debris, and ships with a protective carrying case that doubles as a T-handle for easier pulls. The kit is washable and reusable for routine maintenance at the range or in the shop.
