Possum Hollow Bore Guide #295i .17 Hornet Fits CZ-527 Integral Port

Possum Hollow bore guides help align the cleaning rod centrally to the bore in order to prevent throat or rifling damage. An O-ring seals the chamber on their centre fire guides and prevent solvents from contaminating the action and trigger and it also helps to keep the bore guide firmly in place.

Note: This bore guide does not have an O-ring on the snout.
