Breakthrough Aluminium Universal Bore Guide

The Breakthrough Aluminium Universal Bore Guide is a precision firearm-cleaning accessory designed to keep the cleaning rod properly aligned with the barrel while protecting the chamber, breech and bore from unnecessary contact. Installed through the action after the bolt has been removed, the guide directs patches, brushes and jags smoothly into the barrel while helping prevent the cleaning rod from bowing, bending or rubbing against critical internal surfaces.

Constructed from durable aluminium, the universal guide accommodates bore sizes from .17 to .416 calibre and is designed for use with most bolt-action rifles. It also includes a specially designed adaptor sleeve for compatibility with the AR-15 platform, increasing its versatility across different firearm types. By supporting controlled breech-to-muzzle cleaning and helping prevent solvents and fouling from entering the action, the Breakthrough Aluminium Universal Bore Guide is a practical addition to any firearm maintenance kit.
