KleenBore Gun Cleaning systems - Kleenpak .22/.223/ 5.56mm Rifle Kit features the best made cleaning components in the industry, neatly housed in a custom organizer tray and then securely packaged in a rugged, reusable storage case. Each kit includes a plastic muzzle guard to protect the crown of the barrel during the cleaning process. Includes Break Free CLP which is a quick and easy gun care that cleans, lubricates, and protects. Classic Rifle Kits utilize precision machined steel rods for enhanced durability and are less apt to bend and break where the sections connect. Engineered like the rods specified by the U.S government, they offer a much better thread system than the competition. Kits are caliber specific, and include the appropriate bore brush and cotton patches. Rods are made of a smooth, high-grade steel for maximum strength, and feature a black oxide finish and rotating handles.
