Possum Hollow Bore Guides protect the chamber and bore of your rifle by guiding the cleaning rod through the barrel. An o-ring seal will be needed to prevent solvents or oils from seeping into the action and trigger mechanism. For optimum performance, add an optional solvent port (sold separately). Solvent Ports fit into the end of the Bore Guide to ease solvent application and end messy spills.NotesSee the Compatibility Chart link below for more specific make/model and cartridge fits FeaturesMachined from solid Delrin100% Solvent Resistant Ensures protection for rifle barrel
