Bore Tech Proof-Positive Nylon Bore Brushes are engineered for superior barrel cleaning without the false copper fouling indications caused by traditional brass brushes. Featuring non-brass cores and threads, these brushes are ideal for use with copper removers such as Bore Tech Eliminator and Cu+2 Copper Remover.

Designed with extra-rigid nylon bristles and double the scrubbing power of standard nylon brushes, they provide faster, more effective cleaning while remaining 100% barrel safe. Available in calibers from .17 to .50, these premium brushes are built for shooters who demand accurate cleaning results and long-lasting performance.
