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, but it also directs the force exerted on the cleaning rod handle allowing tight patches to be pushed more easily.
The Bore Guide is simple to use.
1) Install the appropriate tip for your rifle
2) Remove the bolt and insert guide
3) adjust the sliding collar for a snug fit into the chamber and tighten thumbscrew and you are ready to clean.
