Dewey 20 Caliber 25'' 5-40F Coated Rod

The Dewey 20 Caliber 25'' 5-40F Coated Rod is a purpose-built cleaning rod for .20 caliber rifles that prioritizes barrel protection above all else. The nylon coating won't scratch or damage match-grade rifling, and unlike vinyl alternatives, it resists peeling after repeated use—a real difference when you're maintaining a precision barrel over years of shooting. The smooth-turning ball bearing handle reduces friction and fatigue during longer cleaning sessions, making the job less of a chore whether you're working on a varmint rifle or a benchrest gun.

This rod arrives ready to work. Dewey supplies an extra-long jag that threads directly onto the rod and accepts patches either wrapped around or slid over the end—flexibility that matters when you're finding your preferred patch configuration. The jag is sized for the rod's male thread, so there's no fussing with adapters for this step. At 25 inches, the rod is long enough to reach the full bore on most .20 caliber barrels while remaining manageable for safe handling.

One important note: the 20 caliber series rods use a 5-40 female thread and do not include a brush adapter, so if you need to attach standard brushes or other accessories, you'll source those separately. Many serious reloaders and match shooters keep dedicated rods for each caliber anyway, so this rod becomes a focused, dependable tool for your .20 caliber work. Pair it with a breech or muzzle guide for maximum protection of that investment in a quality barrel.

Frequently Asked Questions

Will this rod scratch my barrel?

No. The nylon coating is specifically designed to protect rifling from damage, and it won't peel or flake off like some vinyl coatings do. Many shooters with precision barrels prefer Dewey rods for this reason.

Can I use standard brush adapters with this rod?

The 20 caliber series does not include a brush adapter, so you'll need to source adapters separately if you want to attach standard 8-32 thread brushes or other accessories.

What patches work with the included jag?

The extra-long jag accepts patches either wrapped around the jag or slid over the end, giving you flexibility to match your preferred cleaning method.

Is a bore guide necessary?

Dewey recommends using a breech or muzzle bore guide when cleaning to further protect your barrel and ensure the rod stays centered in the bore.
