This 1/2 lb. cleaning system replaces over 3 lbs. of conventional gear. This is the first shotgun cleaning product to clean the chamber, forcing cone and bore completely in a one step operation. If the shotgun is cleaned after each use, lead and plastic in the bore are a thing of the past. The shotgun bore can be cleaned on the line while shooting without disassembly. This is made possible with components such as the Memory-Flex cleaning rods, a 12/10 gauge bore brush, all-caliber patches, and the Otis O85 Ultra Bore Solvent. The Patch Savers make it easy for your swab to fit any size shotgun from.410 to 12/10 gauge, and they help provide a snug 360 degree fit as the patch travels through the bore and out the muzzle. Also included is a T-handle bar, a thread connector, and a bore reflector/flag safety. By using the Shotgun Cleaning System, fast and accurate cleaning can be accomplished in minutes. Gauge: .410 Bore - 10 Gauge Shotguns Dimensions: 4 x 4 x 2.
