The Dewey Handgun Bore Brush (.20 Caliber) 3-Pack is a bore brush from Dewey (Dewey part no. B-20PNA), built to scrub .20 caliber bores clean of copper, lead, and powder fouling. It threads onto any standard cleaning rod and is meant for hands-on handgun maintenance rather than a one-and-done wipe-down. Shooters who put rounds downrange regularly know a brush wears out well before a rod does, and this one is sized specifically so it doesn’t ride loose or bind going down the bore. It’s a straightforward, no-frills part of any cleaning routine, whether that’s after a range day or before a hunt. Pair it with the right solvent and patches from our gun cleaning supplies lineup and a proper cleaning takes minutes, not an afternoon.

Key Specifications

• Bore diameter is sized for .20 Caliber, so the fit is snug against the rifling instead of the sloppy pass-through of an oversized brush or rod.
• Built for handgun bores, matching the shorter, tighter cleaning runs a handgun action calls for.
• Threaded 5-40, the standard cleaning-rod thread pattern most brushes, jags, and mops in this size range already use.
• Sold as a 3-pack, so a worn brush doesn’t mean a trip back to the store mid-cleaning session.
