The Kleen-Bore A191N is a nylon-bristle bore brush sized for 10mm, .40, and .41 caliber handguns. If you run any of those cartridges through a semi-auto or revolver, this brush is a straightforward addition to your cleaning kit. Nylon bristles are gentler on bore surfaces than brass, making them a smart choice for regular maintenance without risk of accelerated wear. The 8-32" thread standard fits most popular cleaning rod systems, so you can thread it onto what you already own and get to work.
Handgun bores collect copper, lead, and powder residue with every shot. A dedicated bore brush rated for your specific caliber does the job more effectively than a one-size-fits-all approach. The A191N's soft bristles break up fouling without imposing the aggressive scrubbing action of brass, which matters if you shoot frequently and want your barrel lasting as long as possible.
Whether you're maintaining a carry gun, a range pistol, or a defensive handgun, routine bore cleaning extends accuracy and longevity. This brush fits naturally into a basic cleaning routine and costs little enough to keep one in your range bag and another at home.
