Won't produce blue-green stains on your patches that can be misinterpreted as "false positive" indications of copper fouling, so you'll know when your bore really is copper-free. Similar in hardness to brass, Copper Eliminator parts won't scratch the bore or damage the muzzle, and they'll stand up to hard use. Top-quality steel rods have the same tough, nylon outer coating and ball-bearing smooth rotating handle as standard Dewey rods, with an 8-32 female threaded aluminum ferrule. Each rod comes wit Mfg: Dewey SPECS: Steel rod, black nylon coated, with aluminum fittings and red plastic handle. 8-32 female threads. Available in 36", 40", and 44" lengths. Jag included.
