Hoppe's Universal Bore Guide

Keeps solvents from dripping into action and prevents excessive cleaning rod contact with the rifling lands closest to the chamber.

• Three interchangeable chamber tips to fit .17 to .416 caliber.
• Aluminum action collar fits .695"/.700" (17.65mm/17.78mm) diameter bolt actions of any action length.
• Threaded brass pin locks the guide into the action in place of the bolt to allow proper cleaning from the breech.
