Breakthrough Clean BT2702847PBBB .270/.284 Cal Phosphorus Bronze Brush

The Breakthrough Clean BT2702847PBBB Phosphorus Bronze Bore Brush delivers superior cleaning performance for .270 and .284 caliber rifles. This precision-engineered brush removes stubborn fouling that standard cleaning patches leave behind, ensuring optimal barrel condition and consistent accuracy.

What Makes This Different

Phosphorus bronze bristles provide the ideal balance of cleaning power and barrel protection, unlike steel brushes that can damage rifling or nylon brushes that lack scrubbing strength. The bronze alloy composition resists corrosion while maintaining bristle integrity through hundreds of cleaning cycles. Each bristle is precisely cut to 8-32 thread specifications for secure attachment to standard cleaning rods.

Key Features

• Phosphorus bronze bristles remove copper fouling and carbon buildup effectively
• 8-32 thread pitch fits all standard cleaning rod systems
• Corrosion-resistant bronze alloy construction for extended service life
• Precision-calibrated bristle density optimized for .270/.284 bore diameter
• Double-wound core design prevents bristle separation during use
• Compatible with all rifle cleaning solvents and oils
• Made in USA with quality control standards for consistent performance

This bore brush excels in maintaining match-grade accuracy for precision rifles and hunting firearms. The phosphorus bronze material removes metal fouling without scratching the barrel surface, making it suitable for both chrome-lined military barrels and precision match chambers. Regular use prevents accuracy degradation caused by fouling buildup, particularly important for long-range shooting applications.
