Dewey Adjustable Bore Saver Rod Guide – ABS-4 (.338–.358 Cal, .695–.700 Bolt Diameter)

Heavy-caliber cleaning done right.
The Dewey ABS-4 Bore Saver Rod Guide is built for serious calibers—from .338 to .358—offering superior protection during cleaning. Replacing your rifle’s bolt, it ensures your cleaning rod enters perfectly centered into the bore, protecting the chamber, throat, and rifling from damage and wear.

🔧 Key Features:

✅ Optimized for .338–.358 Calibers
Ideal for precision rifles chambered in hard-hitting cartridges such as .338 Lapua, .340 Weatherby, .35 Whelen, and others.

✅ Bolt-Replacement Fit
Slides into your action in place of the bolt, aligning the rod and preventing misalignment that leads to throat wear.

✅ Adjustable Aluminum Collar with Brass Pin
Locks in tight to your rifle’s bolt length using a precision-machined brass pin for universal fit across multiple models.

✅ Chamber-Sealing O-Rings
Keeps cleaning solvents and oils from seeping into the action, magazine, or trigger assembly.

✅ Solvent Port Included
Built-in port makes applying solvents clean and controlled—no mess, no waste.
