KleenBore A190N Bore Brush .38/.357/9mm Nylon Bristles 8-32 Thread

The KleenBore A190N bore brush delivers thorough cleaning for .38 Special, .357 Magnum, and 9mm handguns without the aggressive scraping of bronze bristles. This nylon-bristled cleaning tool removes fouling while protecting barrel rifling from damage.

What Makes This Different

Nylon bristles provide effective cleaning power without the metal-on-metal contact that bronze brushes create. The A190N maintains consistent bristle tension throughout its service life, unlike cheaper brushes that lose stiffness after repeated use. Standard 8-32 threading ensures compatibility with most cleaning rod systems, while the caliber-specific sizing delivers optimal contact with bore surfaces.

Key Features

• Nylon bristles protect barrel rifling from scratching and wear
• 8-32 thread pitch fits standard cleaning rods and handles
• Sized for .38 Special, .357 Magnum, and 9mm Luger chambers
• Maintains bristle stiffness through extended cleaning sessions
• Chemical-resistant construction withstands solvents and cleaners
• Looped and twisted wire core prevents bristle separation
• Made in USA with quality control standards

This brush excels in regular maintenance routines where frequent cleaning is required. Competition shooters benefit from the gentler cleaning action that preserves barrel accuracy over thousands of rounds. The nylon construction resists chemical breakdown from copper solvents and powder fouling removers, maintaining cleaning effectiveness longer than natural fiber alternatives.
