Bore Tech understands the need for premium
quality nylon brushes, which is why
they have constructed these “double wound”
Proof-Positive Nylon Brushes that feature
superior construction and materials. These brushes
have twice as many bristles as competing brands to
double the scrubbing action and shorten the cleaning process.
Features oversized bristles for added strength, and non-brass cores and
couplers that prevent the appearance of copper fouling remaining in your
bores. The .17 and .20 caliber rifle brushes are 1" shorter in length to
reduce the force needed to push the brush through and prevent barrel
damage. For best results use Proof-Positive Nylon Brushes with fast acting
copper cleaners like Bore Tech’s Eliminator and CU+2 Copper Remover.
