Breakthrough Clean BT4445PBBB .44/.45 Cal Phosphorus Bronze Brush

The Breakthrough Clean BT4445PBBB Phosphorus Bronze Bore Brush delivers superior cleaning performance for .44 and .45 caliber firearms. This precision-engineered brush removes stubborn fouling that standard brushes leave behind, ensuring consistent accuracy and reliable function shot after shot.

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 bend under pressure, this brush maintains its shape while effectively scrubbing away carbon, copper, and lead deposits. The bronze alloy resists corrosion and maintains bristle integrity through hundreds of cleaning cycles.

Key Features

• Phosphorus bronze bristles for optimal cleaning without barrel damage
• Precision-wound construction maintains bristle alignment
• Standard 8-32 threading fits most cleaning rods
• Compatible with .44 Magnum, .45 ACP, .45 Colt, and .454 Casull
• Corrosion-resistant bronze alloy construction

• Professional-grade manufacturing standards

This brush excels in removing the heavy fouling common to large-bore handgun cartridges. Competition shooters rely on its consistent performance to maintain match-grade accuracy between stages. Law enforcement armorers appreciate its durability during high-volume cleaning operations. The bronze bristles effectively strip away the stubborn residue left by jacketed bullets and cast lead projectiles without scoring the bore surface.
