The Hoppe's No. 9 3-pack brush/swab kit includes cleaning swab, Tornado brush and Phosphor Bronze brush. Hoppe's cleaning swabs are 100% cotton. These swabs are soft and will not scratch smooth bores. Known as "The Gunsmith's Brush," Hoppe's Tornado brush has a special spiral-wound design that's highly effective for cleaning bores. The stainless steel loops eliminate any bristle ends that could leave scratches, yet removes fouling without damaging bore. The Hoppe's No. 9 Phosphor Bronze brush is most effective on lead. The stout bristles allow for an efficient cleaning.
