Possum Hollow Bore Guide #392i - .243 Winchester, 6.5 X 55 SE, Creedmoor Fits Sako S20 with Integral Port

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.

An integrated solvent port helps to avoid messy solvent drips or spills.
