Breakthrough Clean BT50NBB Nylon Bore Brush .50 Cal Cleaning

The Breakthrough Clean BT50NBB delivers thorough bore cleaning for .50 caliber firearms without the aggressive scrubbing that bronze brushes can cause. This precision-engineered nylon bristle brush removes fouling and debris while protecting expensive barrel surfaces from scratches and excessive wear.

What Makes This Different

Unlike traditional bronze brushes that can embed copper particles in barrel steel, this nylon bristle design provides effective cleaning action without metal-on-metal contact. The engineered bristle density and stiffness remove carbon buildup and powder residue while maintaining consistent bore dimensions. Professional armorers and precision shooters choose nylon brushes for regular maintenance to preserve barrel accuracy over thousands of rounds.

Key Features

• Nylon bristles prevent barrel damage while maintaining cleaning effectiveness
• .50 caliber specific sizing for proper bore contact and cleaning coverage
• Standard 8-32 threading fits most cleaning rod systems
• Chemical-resistant construction withstands aggressive solvents and cleaners
• Looped and wound bristle construction prevents bristle loss during use
• Reinforced core design maintains brush shape through repeated cleaning cycles
• Compatible with .50 BMG, .500 S&W, and other .50 caliber platforms

This brush excels in both field maintenance and detailed cleaning sessions. The nylon bristles maintain their shape and cleaning ability through hundreds of passes, making it ideal for high-volume shooters and competitive marksmen who clean frequently. The non-metallic construction eliminates concerns about galvanic corrosion when used with modern cleaning solvents and copper-removing chemicals.
