Abstract: A method for cleaning and blocking the bore of the firearm includes inserting the cleaning and blocking device into the bore where the cleaning and blocking device includes a cleaning body having a foam core enclosed in a tubular sheath. A first pull-cord is coupled to a first end of the cleaning body and a second pull-cord is coupled to a second end of the cleaning body. A locking mechanism is additionally coupled to the first and second pull-cords. The method further includes pulling the cleaning body back and forth at least once through the bore with at least one of the pull-cords. The method also includes locking the cleaning and blocking device by coupling a lock to the locking mechanism of the first and second pull-cords.
