Our crew of tactical weapons experts developed these fine 5.56mm cleaning kits to give the M16/AR-15 shooter a handy, carry-along system that fits snug in the storage compartment of A-1/A-2 buttstocks. Standard Kit includes a government-type 5-piece cleaning rod (with loop), bronze bore brush, bronze chamber brush, double-ended parts cleaning brush, and a heavy Nylon pouch tapered correctly for a rattle-free fit. Deluxe Kit adds a solvent-resistant Nylon chamber brush, and 25-Pak of mil-spec cleaning patches. Detailed instructions in both kits guide you through the cleaning process.
