A gun barrel cleaning device includes an elongated shaft having a driving head at one end dimensioned for engagement with a battery powered reversible electric screw driver. One of a variety of available cleaning implements is secured to the shaft through a pair of cooperating threaded fasteners. An elongated extension shaft may be employed depending upon the length of a gun barrel to be cleaned. The fasteners form a rotary driving connection which enable the cleaning implement to be rotated in either a forward or reverse direction within a gun barrel. The cleaning implement may take the form of a rotary brush having a spiral bristle array with a pitch corresponding to the rifling groove pitch of a barrel to be cleaned, a slotted holder for a fabric cleaning patch, or a conical threaded bullet extractor.
