Breakthrough Clean BT12GNBB Nylon Bristle Bore Brush 12 Gauge

The Breakthrough Clean BT12GNBB Nylon Bristle Bore Brush delivers thorough cleaning for 12-gauge shotgun barrels without the aggressive scraping of bronze alternatives. This precision-engineered cleaning tool removes fouling and debris while protecting barrel surfaces from damage that can affect accuracy over time.

What Makes This Different

Nylon bristles provide effective cleaning power while remaining gentle on barrel surfaces, including chrome-lined and stainless steel bores. Unlike bronze brushes that can leave metal deposits, the BT12GNBB removes carbon buildup and powder residue without abrading the rifling or bore surface. The synthetic bristles maintain their shape through hundreds of cleaning cycles, delivering consistent performance that bronze alternatives cannot match.

Key Features

• Nylon bristles safe for all barrel finishes including chrome, stainless steel, and carbon steel
• Standard 8-32 threading fits most cleaning rod systems
• Precision-wound bristle pattern ensures complete bore contact
• Chemical-resistant construction withstands all cleaning solvents
• Designed specifically for 12-gauge shotgun bore dimensions
• Non-embedding bristles won't leave residue in barrel
• Durable construction maintains bristle integrity through extended use

Field testing demonstrates the BT12GNBB effectively removes lead, plastic, and powder fouling from hunting and sporting shotgun barrels. The brush works efficiently with both traditional and modern cleaning solvents, making it suitable for competitive shooters who clean frequently and hunters who need reliable maintenance tools. Weather-resistant nylon construction performs consistently in field conditions where metal brushes might corrode.
