Patent ID: 8661724

Claim:
A device to clean a firearm bore comprising: a. a molded plastic shank having: i. parallel rings spaced respectively between parallel spacers along a mid-length of the shank; and ii. a threaded free end adapted in size and shape to be screwed into a gun cleaning rod; b. a polyurethane cover over all the rings and all the spacers, wherein the cover is affixed by thermal bonding to the shank before the device is initially held by an end-user and subsequently used by the end-user to clean the firearm bore; c. rifling-cleaning means for enabling the device to fit into any rifling within the bore for cleaning, wherein the means comprises: i. the polyurethane cover is wider than the bore, prior to the device cleaning the bore, whereby the cover compresses upon the device being placed inside the bore; and ii. compression of the polyurethane cover, within the bore, is limited by the rings and spacers; and d. whereby when the device is pushed within the bore: i. the device is tightly fit into the bore and loosens residue for the polyurethane cover to absorb; and ii. compressive forces, seeking to expand the compressed polyurethane cover within the bore, force the cover to fit into any rifling within the bore for cleaning.
