Abstract: An organization including a pump member defined by an elongate cylindrical body mounting a flexible cylindrical body at a forward end thereof, with a piston coaxially and slidably mounted within the rigid cylindrical body operative through a manually manipulated coaxial rod, with the cleaning brush mounted coaxially to the piston through the flexible cylindrical body to effect plunging and cleaning of a black powder firearm bore. A first conduit pipe directs water within the rigid cylindrical body forwardly of the piston to direct cleaning water through the firearm bore and further provides a nipple adapter to direct the fluid exteriorly of the firearm during a cleaning procedure.
