KleenBore A184 Bore Brush 20 Gauge 5/16-27 Phosphor Bronze

The KleenBore A184 bore brush delivers professional-grade cleaning performance for 20 gauge shotguns with its phosphor bronze bristle construction. This brush removes stubborn fouling and residue that standard cleaning patches leave behind, ensuring optimal barrel condition and consistent shot patterns.

What Makes This Different

Phosphor bronze bristles provide the ideal balance between aggressive cleaning power and barrel protection, unlike steel brushes that can cause wear or nylon brushes that lack scrubbing ability. The 5/16-27 threading ensures secure attachment to most standard cleaning rods, preventing the brush from loosening during use. Each bristle maintains its shape through multiple cleaning sessions, delivering consistent performance across hundreds of uses.

Key Features

• Phosphor bronze bristles remove copper fouling and powder residue effectively
• 5/16-27 thread pitch fits standard cleaning rods and handles
• 20 gauge specific diameter ensures proper bore contact
• Corrosion-resistant construction withstands solvents and cleaners
• Twisted wire core maintains bristle alignment during cleaning strokes
• Professional-grade materials used by gunsmiths and armorers
• Compact design allows storage in field cleaning kits

This brush handles the demanding cleaning requirements of high-volume shooters and competitive clay sports enthusiasts. The phosphor bronze material excels at removing plastic wad residue and powder fouling that accumulates during extended shooting sessions. Unlike disposable cleaning patches, this brush provides mechanical scrubbing action that breaks loose embedded debris from barrel grooves and chamber areas.
