KleenBore A187 10 Gauge Shotgun Bore Brush - Phosphor Bronze

The KleenBore A187 bore brush delivers thorough cleaning for 10 gauge shotguns with its phosphor bronze bristle construction. This specialized cleaning tool removes fouling and residue that standard patches cannot reach, maintaining barrel integrity and consistent shot patterns.

What Makes This Different

Phosphor bronze bristles provide the ideal balance of cleaning effectiveness and barrel protection, being harder than lead and plastic fouling but softer than steel barrels. The 5/16-27 thread pitch ensures secure attachment to most standard cleaning rods without wobbling or binding. Unlike brass brushes that can leave residue, phosphor bronze maintains its shape through repeated use while effectively scrubbing away stubborn deposits.

Key Features

• Phosphor bronze bristles for optimal cleaning without barrel damage
• 5/16-27 thread pitch fits standard cleaning rods
• Precision-sized for 10 gauge shotgun bores
• Corrosion-resistant construction for long service life
• Maintains bristle tension through multiple cleaning cycles
• Compatible with solvent-based and water-based cleaners
• Professional-grade manufacturing standards

This bore brush excels in removing plastic wad fouling, powder residue, and lead deposits that accumulate during waterfowl hunting and clay shooting. The phosphor bronze material resists chemical breakdown from cleaning solvents while maintaining aggressive scrubbing action. Regular use prevents accuracy-degrading buildup that can affect shot patterns and potentially damage forcing cones over time.
