Hoppe's BoreSnake Den is a compact carrying case with a built in handle for easy storage between firearm cleanings. It conveniently fits in a range bag or backpack to protect your Boresnake brushes during transport. The lid doubles as convenient pull handle that snaps into the clear case for storage. A one pass solution, BoreSnake uses an integrated bronze brush to scrub out carbon fouling, while the tail clears the barrel of loose debris with a surface area 160x larger than a standard patch. This model is compatible with 22 pistol calibers.
