Possum Hollow Bore Guide #65 - 7MM Remington Magnum Fits Remington, Winchester Model 70, Mauser

A Possum Hollow bore guide aligns the cleaning rod centrally to the bore to prevent throat or rifling damage. O-ring seals the chamber and prevents solvents from contaminating the action and trigger and helps to keep the bore guide firmly in place. Large replacement O-ring fits all guides and solvent port.
