Possum Hollow Bore Guide #95 - .17 HMR Fits CZ-452, CZ-455, CZ-457

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.

Includes groove for ejector clearance.
