Hoppe's Universal Bore Guide

The Hoppe's Universal Bore Guide is a precision cleaning accessory designed to protect your rifle's action and chamber during solvent-based maintenance. By routing cleaning rods through a dedicated bore pathway, this guide prevents solvents from dripping into the action while eliminating excessive rod contact with rifling lands near the chamber—two critical concerns for long-term firearm preservation and accuracy maintenance.

The system uses three interchangeable chamber tips to accommodate calibers from .17 to .416, making it adaptable across most centerfire and rimfire platforms. An aluminum action collar sized at .695"/.700" (17.65/17.78mm) diameter fits standard bolt-action receivers of any length, while a threaded brass pin locks the guide in place of the bolt—allowing breech-to-muzzle cleaning without removing the action from the stock. This design eliminates the risk of rod misalignment and ensures consistent bore contact across the entire cleaning stroke.

Operators maintaining precision rifles, law enforcement duty weapons, or long-range platforms benefit from this accessory. Those performing routine solvent cleaning or copper-removal protocols will appreciate the protection it provides to chamber geometry and action surfaces. The universal design supports multiple calibers in a single kit, making it a practical addition to any serious shooter's maintenance bench.

Bore guides are industry-standard tools in professional gunsmithing and armorer-level maintenance. The Hoppe's Universal model bridges commercial and professional-grade functionality at an accessible price point, making bore-guide protection standard practice rather than specialized equipment.
