Breakthrough Clean BT223PBCBAR .223/5.56 Phosphorus Bronze Chamber Brush

The Breakthrough Clean BT223PBCBAR Phosphorus Bronze Chamber Brush delivers precise cleaning for .223 Remington and 5.56 NATO rifle chambers. This specialized brush removes carbon buildup and fouling that standard cleaning rods miss, maintaining optimal headspace and extraction reliability.

What Makes This Different

Phosphorus bronze bristles provide the ideal balance of cleaning power and chamber protection, unlike steel brushes that can scratch chamber walls or nylon brushes that lack sufficient scrubbing ability. The precisely sized bristles conform to chamber dimensions while the corrosion-resistant bronze construction withstands repeated use with aggressive solvents. This brush specifically targets the chamber area where carbon rings form, extending barrel life and preventing extraction failures.

Key Features

• Phosphorus bronze bristles remove stubborn carbon deposits without damaging chamber surfaces
• Optimized for .223 Remington and 5.56 NATO chamber dimensions
• Standard 8-32 thread fits most cleaning rod systems
• Corrosion-resistant construction withstands harsh cleaning solvents
• Precision-wound bristles maintain shape through extended cleaning sessions

• Compact design allows storage in range bags and cleaning kits

Regular chamber cleaning with this specialized brush prevents the accuracy degradation and reliability issues that plague high-volume shooters. Competition shooters rely on chamber brushes to maintain consistent velocities and eliminate flyers caused by carbon ring interference. The phosphorus bronze construction removes fouling effectively while preserving the critical chamber finish that ensures proper cartridge seating and extraction.
