The KleenBore .32 Cal Handgun Phosphor Bronze Bore Brush (Model A189) is a dedicated barrel maintenance tool engineered to remove lead fouling, copper build-up, and powder residue from .32 calibre handgun bores. Constructed with straight-wire phosphor bronze bristles, a wound steel core, and a brass connector, it delivers the mechanical stiffness required to clean rifling grooves without scratching or damaging steel barrels. Designed for manual push-and-pull cleaning routines, it weighs approximately 0.01 lb (~4.5 g) and comes packaged in a clear, reusable plastic protective tube to prevent bristle deformation and contamination during storage.

Key Features

• Straight-Wire Phosphor Bronze Bristles: Uses straight rather than crimped wire bristles to deliver concentrated scrubbing resistance against stubborn carbon and metallic fouling while protecting steel rifling.
• Safe Core Construction: Built with a looped, rounded core wire tip to prevent gouging the barrel throat or rifling lands during insertion.
• Industry-Standard Interface: Features an industry-standard #8-32 male thread that connects directly to standard commercial cleaning rods.
• Protective Packaging: Ships in a clear, reusable plastic storage tube to keep bristles aligned and uncontaminated inside range bags and cleaning kits.

Who is the Kleenbore .32 Cal Handgun Phosphor Bronze Bore Brush for?

• Handgun target shooters maintaining .32 calibre firearms — Sized for .32 calibre handgun bores to provide the exact wall-contact diameter needed to scrub lead and powder fouling out of .32 ACP, .32 S&W, and .32 H&R Magnum barrels using this 0.01 lb phosphor bronze bore brush.
• Competitive shooters utilizing American-standard maintenance rods — Features an industry-standard #8-32 male thread, allowing direct attachment to standard cleaning rods without thread adapters.

Less suitable for: Handgun bores smaller than .30 calibre where the brush diameter causes severe binding, larger bores (such as 9mm, .38, or .40 calibre) where contact pressure is insufficient, power drill operation, or barrel cleaning routines utilizing aggressive ammonia-based copper solvents; use calibre-specific brushes, manual cleaning rods, or chemical-resistant nylon bore brushes instead.
