.17 & .20 Caliber Rod Brush Adapter

The .17 & .20 Caliber Rod Brush Adapter is an essential accessory for precision rifle maintenance, designed specifically for shooters who use J. Dewey cleaning rod systems. This adapter solves a critical compatibility challenge: it bridges the thread mismatch between Dewey's 5/40 female-threaded rods and standard brush systems that feature 8/32 male threads. Whether you're maintaining a rimfire precision rifle or a specialty centerfire platform, this adapter ensures your existing brush collection works seamlessly with your Dewey rod setup, eliminating the need for redundant cleaning equipment.

This adapter features precision-engineered 5/40 male to 8/32 female threading, allowing it to mate directly with both J. Dewey nylon-coated and stainless steel rods while accepting any industry-standard brush with 8/32 male threads. The compact design—measuring just 2.75 inches in length and weighing only 0.06 pounds—adds minimal bulk to your cleaning kit while maintaining the durability and accuracy-critical tolerances that Dewey rods are known for. The machined construction ensures consistent thread engagement and reliable performance across repeated cleaning cycles, making it an indispensable tool for serious shooters who demand reliability and precision in firearm maintenance.

Competitive shooters, gunsmiths, and dedicated handloaders benefit most from this adapter, particularly those who have invested in quality Dewey rod systems for their .17 HMR, .17 Mach 2, .20 Tactical, or other specialty caliber rifles. Installation is straightforward—simply thread the adapter onto your J. Dewey rod's female 5/40 socket, then attach your standard brush to the adapter's 8/32 female threads. This compatibility solution maintains the precision advantages of Dewey's reputation for quality bore cleaning while allowing you to maximize your existing brush inventory. For shooters seeking reliable bore maintenance without equipment redundancy, this adapter represents a cost-effective upgrade to any cleaning routine.
