Breakthrough Clean BT22PBBB .22 Cal Phosphorus Bronze Bore Brush

The Breakthrough Clean BT22PBBB Phosphorus Bronze Bore Brush delivers superior fouling removal for .22 caliber firearms with its precision-engineered bristle design. This cleaning tool removes stubborn copper deposits and powder residue that standard brushes often leave behind.

What Makes This Different

Phosphorus bronze construction provides the ideal balance between effective cleaning and barrel protection, unlike harder steel brushes that can cause wear or softer brass brushes that bend under pressure. The bristles maintain their shape through hundreds of cleaning cycles while generating enough friction to eliminate built-up fouling. Each brush features precisely wound bristles that conform to rifling patterns without damaging the bore surface.

Key Features

• Phosphorus bronze bristles resist corrosion and maintain cleaning effectiveness
• .22 caliber specific diameter ensures proper bore contact
• Standard 8-32 thread fits most cleaning rod systems
• Double-wound bristle construction prevents premature bristle loss
• Heat-treated core wire provides structural integrity during use
• Compatible with all .22 LR, .22 WMR, and .223/5.56 cleaning protocols
• Manufactured to precise tolerances for consistent performance

This bore brush excels in competitive shooting environments where accuracy depends on pristine bore conditions, as well as high-volume training scenarios where rapid fouling buildup occurs. The phosphorus bronze material resists chemical cleaning solvents while maintaining bristle flexibility across temperature ranges. Law enforcement armorer programs rely on this brush design for maintaining duty rifles and training firearms.
