The Dewey Cleaning Rod Guide (.338) is a muzzle or rod entry guide from Dewey (Dewey part no. ABS4S), built to center a cleaning rod on .338 instead of letting it wander off-axis. Cleaning a rifle from the muzzle without a guide risks the rod contacting and eventually wearing the crown, the single most accuracy-critical surface on a barrel. This guide centers the rod so repeated cleaning passes don’t slowly degrade accuracy over the life of the barrel. It’s inexpensive insurance for a barrel that’s otherwise cared for properly. Combine it with a rod and brush from our gun cleaning supplies lineup for a complete, crown-safe cleaning setup.

Key Specifications

• Bore diameter is sized for .338, so the fit is snug against the rifling instead of the sloppy pass-through of an oversized brush or rod.
• Built as a short muzzle or rod-entry guide rather than a full-length rod, keeping a separately sold cleaning rod centered instead of running the length of the bore itself.

Frequently Asked Questions

What caliber is the Dewey Cleaning Rod Guide (.338) sized for? It’s built for .338, so choose the listing that matches your firearm’s actual bore diameter rather than a close approximation.

Does this replace my cleaning rod? No, it’s a short guide that centers a separately sold cleaning rod; it does not run the length of the bore itself.

Do I actually need a rod guide? If you clean from the muzzle, yes; it keeps the rod off the crown, which is the most accuracy-critical part of the barrel.
