This CVA tool is designed specifically to clean your CVA Muzzleloaders with a Quick Release Breech Plug. The kit includes one hand turned drill that is used to clean fouling out of the cleaning channel. The drill is designed to clean the large channel and the pick is designed to clean the small channel. Simply insert the tool with the larger diameter into the primer pocket and twist in a clockwise direction by hand while gently pushing the tool into the breech plug. Stop when the handle bottoms out in the primer pocket. This tool cleans both flash channel and primer pocket. Insert the tool with the pick into the primer pocket and flash channel until it enters the flash hole.
