Possum Hollow Bore Guide #42i with Integrated Solvent Port - .270 Winchester, .308 Winchester Fits Sako 75, 85, Integrated Solvent Port

The use of a bore guide otherwise known as a rod guide aligns the cleaning rod centrally to the bore to prevent throat or rifling damage. An 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.
