Dewey
The J. Dewey ABS-4S is an adjustable bore saver rod guide designed to protect your rifle's chamber and action during cleaning—an essential accessory for anyone running a scoped rifle in .338 to .358 caliber. This 10-inch rod guide replaces your bolt and keeps your cleaning rod centered and safe, preventing the accidental damage that can cost you accuracy or worse. It's built for shooters who care about their gear and want to clean their rifles properly without worry.
The core feature is straightforward: a rubber O-ring seal that keeps bore solvent and cleaning chemicals out of your action, trigger group, and magazine. Contamination from aggressive cleaners can gum up your trigger or corrode internal parts over time. The ABS-4S eliminates that risk by isolating the bore cleaning process. An aluminum collar with a threaded brass adjustment pin lets you dial the guide to your specific action length in seconds—no guessing, no fumbling with shims or spacers.
The 10-inch length is the right choice if you're running a short to medium power scope and want sufficient hand clearance to work the cleaning rod without bumping your objective lens or turrets. (If you're using a long varmint or target scope and need more clearance, Dewey offers a 13-inch version.) Just remember: you'll need a cleaning rod that's 10 inches longer than your barrel to pair with this guide. That's not a limitation—it's the system working as designed.
This is real-world rifle maintenance gear: tough, simple, and built to outlast years of hard use. If you're serious about keeping your rifle clean and protecting its internals, the ABS-4S is the kind of small-dollar upgrade that pays dividends in reliability and peace of mind.
| Caliber Range | .338–.358 |
| Rod Guide Length | 10" |
| Material | Aluminum collar with rubber O-ring seal and brass adjustment pin |
| Compatibility | Scoped rifles; requires cleaning rod 10" longer than barrel length |
You'll need a cleaning rod that is 10 inches longer than your barrel. For example, if you have a 24-inch barrel, you need a 34-inch rod. The rod guide is 10 inches long and positions the guide section at the bore.
The 10-inch guide provides adequate clearance under short and medium-length scopes. If you're using a long varmint or target scope and need additional clearance above the action, the 13-inch version is the better choice.
The rubber O-ring creates a barrier that seals out bore solvent and cleaning chemicals, preventing them from running down into your trigger group, magazine, or action internals where they can cause corrosion or gum up moving parts.
Yes. The threaded brass adjustment pin on the aluminum collar allows quick adjustment to fit your specific action length. No tools or complicated setup required—you dial it in and tighten it down once, then it stays secure.
