Finally, A Cleaning System that's quick and easy! The Bore Snake™ is an all-in-one cleaning tool that pulls through your barrel and cleans it thoroughly in just a few seconds. A weighted brass drop-through cord easily slips through the barrel to get the Bore Snake™ started. You just grab the end and pull the rest of it through. The "business end" of the Bore Snake™ has a whole bunch of surface area impregnated with brushes and floss (160X more floss than a patch). One pass with the Bore Snake equals several passes with conventional cleaning tools.
