Simply the fastest and most convenient way to clean your gun barrel, be it a pistol, a rifle or a shotgun. Simply drop the weighted end down the barrel, from breach to muzzle and pull through. Do so with or without solvent, as best suites you needs. One pull runs a copper bristle brush as well as a wide long swab down the length of your barrel. You do not even have to disassemble the weapon to clean! Can be complete in seconds, and your barrel will be ready for another session on the range or in the field.
