This is a Tipton Bore Guide, model 777-888.
The Tipton(R) 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.
Features:
Protects Chamber & Bore From Damage
Integrated Solvent Port
Fits Most Bolt Action Rifles & AR-15s
