Birchwood Casey 41281 Bronze Cleaning Brush .40 Cal Bore

The Birchwood Casey 41281 bronze cleaning brush removes stubborn fouling and carbon buildup from .40 caliber barrels with aggressive scrubbing action that won't damage rifling. Professional gunsmiths and competitive shooters rely on bronze brushes for deep cleaning that patches alone cannot achieve.

What Makes This Different

Bronze bristles strike the optimal balance between cleaning effectiveness and barrel protection, unlike steel brushes that can wear rifling or nylon brushes that lack scrubbing power. The phosphor bronze construction resists corrosion while maintaining bristle integrity through hundreds of cleaning cycles. Standard 8-32 threading ensures compatibility with most cleaning rod systems without wobble or binding.

Key Features

• Phosphor bronze bristles remove lead, copper, and carbon fouling effectively
• Precision-sized for .40 S&W, 10mm Auto, and .40-65 Winchester chambers
• Standard 8-32 male threads fit most cleaning rod systems
• Corrosion-resistant bronze construction for extended service life
• Bristle density optimized for thorough bore contact without over-pressure
• Compatible with all standard gun cleaning solvents and oils
• Professional-grade construction used by gunsmiths nationwide

Regular use maintains barrel accuracy by preventing fouling accumulation that affects bullet trajectory and velocity consistency. Law enforcement armorers specify bronze brushes for department firearms because they clean thoroughly without accelerating barrel wear. The brush handles both light maintenance cleaning and heavy fouling removal after extended shooting sessions or corrosive ammunition use.
