The Walker’s SME Bore Rope Cleaner (part no. GR503) is built for .50 caliber bores, using a two-pass pull-through system designed to get more cleaning done per pull than a single-pass rope. The weighted rope carries an integrated brush and patch pad through the bore, cutting down the number of passes needed to clear heavy fouling from a big-bore rifle or muzzleloader. At 6.8 inches coiled, it stores compactly in a range bag despite handling one of the larger bore diameters in the Knockout lineup.
