Breakthrough Clean BT30NBB .30 Cal Nylon Bristle Bore Brush

The Breakthrough Clean BT30NBB Nylon Bristle Bore Brush delivers thorough .30 caliber bore cleaning without the aggressive metal-on-metal contact that can damage rifling over time. This precision cleaning tool removes fouling and debris while protecting the barrel's critical surfaces from scratches and wear.

What Makes This Different

Unlike traditional bronze brushes that can leave residue and potentially damage sensitive barrel coatings, this nylon bristle design provides effective cleaning action without metal contamination. The synthetic bristles maintain their shape through hundreds of cleaning cycles while generating less friction heat during use. Professional armorers and competitive shooters choose nylon brushes for maintaining match-grade barrels where preserving rifling integrity is paramount.

Key Features

• Nylon bristles prevent barrel damage and metal residue contamination
• Standard 8-32 threading fits most .30 caliber cleaning rods
• Precision-sized for .30/.308/7.62mm bore diameters
• Chemical-resistant construction withstands aggressive solvents
• Maintains bristle integrity through extended use cycles
• Compatible with .30-06, .308 Winchester, .300 Win Mag, and 7.62x51 NATO
• Manufactured to consistent dimensional tolerances for optimal fit

This brush excels in maintenance routines for precision rifles, hunting firearms, and tactical weapons where barrel longevity matters. The nylon construction proves particularly valuable for coated barrels, chrome-lined bores, and expensive match barrels that require gentle yet effective cleaning. Competitive shooters rely on nylon brushes to maintain sub-MOA accuracy standards without compromising barrel life through aggressive cleaning practices.
