Breakthrough Clean BT2702847NBB .270/.28 Cal Nylon Bore Brush

The Breakthrough Clean BT2702847NBB Nylon Bristle Bore Brush delivers thorough cleaning power for .270 and .28 caliber firearms without the aggressive scrubbing that can damage rifling. This precision-engineered cleaning tool removes fouling and debris while protecting barrel integrity.

What Makes This Different

Unlike traditional bronze brushes that can leave metallic residue, this nylon bristle design provides effective cleaning action without depositing copper particles in the bore. The engineered nylon bristles maintain their shape through repeated use while being gentle enough for frequent cleaning sessions. The brush features optimal bristle density and stiffness calibrated specifically for .270 and .28 caliber bores.

Key Features

• Nylon bristles eliminate copper fouling concerns found with bronze brushes
• Precision-sized for .270 Winchester, .280 Remington, and 7mm calibers
• Standard 8-32 male thread fits most cleaning rod systems
• Corrosion-resistant construction withstands chemical solvents
• Maintains bristle integrity through hundreds of cleaning cycles
• Non-embedding design prevents bristle fragments in barrel
• Compatible with all major cleaning solvent brands

Field testing demonstrates consistent fouling removal across various powder types and bullet compositions. The nylon construction proves particularly effective with modern copper-plated and polymer-coated projectiles that can bind with bronze residue. Competition shooters benefit from the brush's ability to maintain consistent bore conditions between strings of fire. The design works equally well for hunting rifles requiring seasonal maintenance and high-volume training firearms.
