The Kleenbore 50 Caliber Rope Cleaner (Model RC-50) is an integrated pull-through bore cleaner engineered specifically for .50 calibre (12.7 mm) barrels. Designed for rapid field maintenance and range use, it consolidates bore scrubbing and wiping into a single manual pass from breech to muzzle. The system combines a weighted drop cord, integrated cleaning bristles to loosen fouling, and an absorbent trailing body to sweep away carbon and powder residue without requiring solid rods or loose patches.

Key Features

• Single-Pass Cleaning Action: Uses an integrated brass-weighted drop cord and embedded phosphor bronze bristles to dislodge and clear fouling in one pull.
• High Surface Area: The main cleaning floss delivers up to 160 times more surface area coverage than a traditional cleaning patch.
• Reusable Design: Washable by hand or in a mesh laundry bag, allowing repeated long-term field use.
• Included Maintenance Wipe: Ships with a single BreakFree CLP (Cleaner, Lubricant, Preservative) wipe packet for corrosion protection and lubrication.
• Unpowered Operation: Fully mechanical, manual pull-through design with no batteries or external power required.

Who is the Kleenbore 50 Caliber Rope Cleaner for?

• Shooters of .50 BMG target rifles — Requires an ultra-compact pull-through bore cleaner tailored to exact .50 calibre (12.7 mm) dimensions for clearing powder and carbon fouling at the range without hauling multi-piece rod kits.
• Owners of .50 calibre black powder muzzleloaders — Benefits from a reusable pull-through rope cleaner that applies 160 times more surface area than a standard patch to rapidly sweep out heavy black powder residue between shots.
• Shooters maintaining .50 calibre handguns — Employs a single-pass bore cleaner sized for 12.7 mm bores to perform fast post-shoot clean-ups in large-bore handguns.

Less suitable for: Barrels with dimensions smaller than .50 calibre (12.7 mm) where the rope may jam, larger diameters such as 12-gauge bores where contact is insufficient, or deep copper-stripping tasks requiring prolonged solvent soaks; these applications require a calibre-matched rope cleaner or a traditional solid-rod cleaning kit with brass jags.
