The Kleen-Bore MSR/AR Platform Accessory Cleaning Set (brand part no. 556SET) bundles the components needed to maintain a 5.56mm/.223-caliber modern sporting rifle in one caliber-matched kit. It includes a brass patch holder and brass spear-tip jag for applying patches, a bronze bore brush for scrubbing carbon and copper fouling, a 100% cotton bore mop for solvent and oil application, and a dedicated chamber brush for the areas a standard bore brush cannot reach. Every threaded component uses the #8-32 standard, so the pieces attach directly to a compatible cleaning rod already in a shooter’s kit. It is built specifically for the AR-platform maintenance routine rather than adapted from a general rifle kit from Kleen-Bore.
