The Eliminator Bore Brush by IOSSO Products is made with a new type of fiber. The Nyflex fiber is a stiffer, thicker fiber that holds its shape well and allows for a back and forth action in the bore, unlike the traditional brass and bronze type brushes. The Eliminator brush is wound tightly and has more fiber per inch than any other brush. It may be used many times before wearing out, and is sized closely to tolerance for a snug fit. The shank is a solid construction and has a brass core. With the cobalt blue color fiber, the Eliminator won't be mistaken for any other type brush. It is available in rifle, pistol, shogun and black powder sizes. AR-15 & AR-10 brush kits are available.
