Brownells .17 Cal #5-40 Male Standard Line Bore Brush, Pack of 12

To enhance convenience and reduce costs, we offer custom-made, high-quality bore brushes in bulk packs, as nearly as many are used in the shop as are sold. The shank is a single-piece, looped and wound design, rather than two twisted pieces that are cut off. Our nylon bore brushes are designed to withstand new-generation bore cleaners, which aggressively target copper and bronze-based bullet jacket fouling and can be harsh on bronze cleaning brushes. These nylon brushes resist such cleaners and prevent accuracy-compromising scratches. Precision-engineered steel, meticulously looped and expertly wound to form a robust shank structure
