Breakthrough Clean BT12GPBBB 12 Gauge Phosphorus Bronze Bore Brush

The Breakthrough Clean BT12GPBBB Phosphorus Bronze Bore Brush delivers superior cleaning performance for 12-gauge shotguns with its precision-engineered bronze bristles. This professional-grade cleaning tool removes stubborn fouling and residue that standard brushes leave behind.

What Makes This Different

Phosphorus bronze construction provides the optimal balance of cleaning power and barrel protection, unlike steel brushes that can damage rifling or nylon brushes that lack scrubbing ability. The alloy composition maintains bristle integrity through hundreds of cleaning cycles while generating enough friction to break loose carbon buildup and plastic wad residue. Each bristle is precisely cut to 12-gauge bore specifications for maximum contact with the barrel surface.

Key Features

• Phosphorus bronze bristles engineered specifically for 12-gauge bore diameter
• Standard 8-32 thread attachment fits most cleaning rods and handles
• Corrosion-resistant bronze alloy maintains bristle strength and flexibility
• Precision-wound bristle pattern ensures complete bore coverage
• Professional-grade construction suitable for high-volume cleaning operations
• Compatible with all 12-gauge shotgun barrel lengths and choke configurations
• Manufactured to exact dimensional tolerances for consistent performance

Field testing demonstrates effective removal of powder residue, plastic fouling, and lead deposits in 12-gauge barrels. The bronze bristles maintain their cleaning effectiveness through extended use while remaining gentle enough for frequent cleaning without barrel wear. Competition shooters and law enforcement armorers rely on phosphorus bronze brushes for maintaining accuracy and reliability in high-round-count firearms.
