Description The Tipton® Universal Bore Guide will help protect the bore and action of your rifle by properly aligning the cleaning rod and reducing solvent overflow. Cleaning without a bore guide can allow the rod to “bow” and rub or gouge the chamber and throat of the bore, causing real damage and loss of accuracy. Keeping the rod properly aligned not only protects your barrel, it directs the force exerted on the cleaning rod handle allowing tight patches to be pushed more easily. W with most 17 caliber to 416 caliber centerfire bolt actions. Features 3 interchangeable tips and locks into action to keep solvent, dirt and grime from getting into action and trigger group.
