Breakthrough Clean BT357389MM Nylon Bore Brush .357/.38/.380/9mm

The Breakthrough Clean BT357389MM Nylon Bristle Bore Brush delivers thorough cleaning without the aggressive scrubbing that can damage barrel rifling. This precision-engineered brush removes carbon buildup and fouling while protecting your firearm's bore integrity. Professional gunsmiths and competitive shooters rely on nylon bristles for safe, effective maintenance of precision barrels.

What Makes This Different

Unlike bronze or steel brushes that can cause microscopic scratches over time, this nylon bristle design maintains cleaning effectiveness while preserving barrel accuracy. The bristles resist chemical breakdown from modern solvents and maintain their shape through hundreds of cleaning cycles. Each brush features precisely calibrated bristle density that conforms to barrel grooves without excessive force.

Key Features

• Nylon bristles protect rifling while removing stubborn carbon deposits
• Compatible with .357 Magnum, .38 Special, .380 ACP, and 9mm calibers
• Standard #8-32 threading fits most cleaning rod systems
• Chemical-resistant construction withstands harsh cleaning solvents
• Precision-wound bristles maintain consistent cleaning pressure
• Durable core construction prevents bristle loss during use
• Professional-grade manufacturing ensures dimensional accuracy

This bore brush excels in high-volume cleaning scenarios where barrel preservation matters most. Competition shooters maintain sub-MOA accuracy by using nylon brushes exclusively, while law enforcement armorers appreciate the consistent results across department firearms. The brush effectively removes powder residue and lead fouling without the aggressive action that shortens barrel life. Multiple cleaning cycles produce consistently clean results without degrading the cleaning tool itself.
