Possum Hollow Bore Guide #40 - .22 Hornet Fits Ruger 77

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.

Note: Due to cartridge and chamber dimensional constraints this bore guide is not supplied with an O-ring on the snout.
