KleenBore A188 Bore Brush .22 Cal Handgun 8-32 Thread Bronze

The KleenBore A188 bore brush delivers thorough cleaning for .22 caliber handguns with phosphor bronze bristles that remove fouling without damaging barrel rifling. This precision-threaded cleaning tool maintains accuracy by eliminating powder residue and lead deposits that accumulate during regular shooting sessions.

What Makes This Different

Phosphor bronze bristles provide the ideal balance between aggressive cleaning power and barrel protection, unlike steel brushes that can wear rifling or nylon brushes that lack scrubbing strength. The 8-32 thread pitch ensures secure attachment to standard cleaning rods, preventing wobble during the cleaning stroke. Each bristle maintains its shape through hundreds of cleaning cycles, delivering consistent performance across the brush's service life.

Key Features

• Phosphor bronze bristles remove stubborn lead and powder fouling safely
• 8-32 thread pitch fits standard .22 caliber cleaning rods
• Precise .22 caliber sizing prevents binding in tight chambers
• Corrosion-resistant bronze construction withstands cleaning solvents
• Looped and twisted wire core maintains bristle alignment
• Double-wound design prevents bristle loss during aggressive scrubbing
• Compatible with all .22 LR, .22 WMR, and .22 Short handgun barrels

Regular use prevents accuracy degradation caused by fouling buildup in the barrel crown and rifling grooves. Competitive shooters rely on phosphor bronze brushes to maintain sub-MOA precision during extended practice sessions. The brush effectively removes the waxy lubricants and carbon deposits that accumulate faster in rimfire cartridges compared to centerfire ammunition. Law enforcement armorers specify bronze brushes for duty weapon maintenance because they clean thoroughly without accelerating barrel wear.
