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. This is a complete system that not only efficiently cleans the barrel, but also has the special tools to clean and maintain the receiver, trigger group, bolt, magazine tube, and gas system. 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. Bore obstructions, mud or snow, can be dislodged out the muzzle end. A stuck empty case can be easily knocked out. Fast and accurate cleaning can be accomplished in minutes..
