Breakthrough Clean BT2565NBB Nylon Bristle Bore Brush .25/.6.5mm

The Breakthrough Clean BT2565NBB Nylon Bristle Bore Brush delivers thorough cleaning power without the harsh abrasion of bronze alternatives. This precision-engineered cleaning tool removes fouling and debris while protecting your barrel's rifling and finish.

What Makes This Different

Unlike traditional bronze brushes that can leave metallic residue, the BT2565NBB features high-density nylon bristles that won't scratch or damage barrel surfaces. The bristles maintain their shape through hundreds of cleaning cycles, providing consistent cleaning performance. Standard bronze brushes require frequent replacement and risk barrel wear, while this nylon construction extends both brush life and barrel longevity.

Key Features

• High-density nylon bristles resist deformation and maintain cleaning effectiveness
• Precision-sized for .25 caliber and 6.5mm bore diameters
• 8-32 threaded connection fits standard cleaning rods
• Non-abrasive construction protects barrel rifling and crown
• Chemical-resistant bristles withstand aggressive solvents
• Durable brass core provides structural integrity
• Optimal bristle density ensures complete bore contact

Field testing demonstrates the BT2565NBB effectively removes carbon buildup and copper fouling without the aggressive scrubbing required by softer brushes. Competition shooters value the consistent bore condition this brush maintains between matches. The nylon construction proves particularly beneficial for precision rifles where barrel preservation directly impacts accuracy retention over thousands of rounds.
