Hoppes BoreSnake Viper .338/.340 Cal Rifle Bore Cleaner Rope - Bronze Bristle

The Hoppes BoreSnake Viper is a pull-through bore cleaner rope purpose-built for .338/.340 caliber rifle barrels, getting your bore fouling-free, lubricated, and back in action with a single pass.

Stepping up from the original BoreSnake, the Viper series adds 33% more scrubbing power and a 160x larger cleaning surface, anchored by an integrated set of bronze bristles that loosen stubborn copper and powder fouling while woven floss sections sweep loosened residue out of the bore.

Use is simple: thread the rope through the chamber from the breech end, attach the integrated T-handle, and pull it straight through the muzzle. No cleaning rod, no patches, no solvent pool. The BoreSnake goes anywhere your rifle does, from the bench to the backcountry.

It ships packaged in a compact carrying case (Den) with a built-in handle, so the rope stays clean, contained, and ready between range sessions. One unit per package.
