KleenBore A190 Bore Brush .38/.357/9mm Phosphor Bronze 8-32 Thread

The KleenBore A190 Bore Brush delivers thorough cleaning performance for .38 Special, .357 Magnum, and 9mm handguns with its phosphor bronze bristle construction. This precision-engineered cleaning tool removes fouling and residue that standard patches miss, maintaining barrel accuracy and extending firearm life.

What Makes This Different

Phosphor bronze bristles provide the optimal balance between cleaning effectiveness and barrel protection, unlike steel brushes that can cause wear or nylon brushes that lack scrubbing power. The 8-32 thread pitch ensures compatibility with most standard cleaning rods, while the precisely calibrated bristle density matches the bore diameter for maximum contact without excessive pressure. Each brush maintains its shape through hundreds of cleaning cycles.

Key Features

• Phosphor bronze bristles resist corrosion and maintain flexibility
• 8-32 thread pitch fits standard cleaning rods and handles
• Calibrated for .38 Special, .357 Magnum, and 9mm Luger chambers
• Looped and wound bristle construction prevents shedding
• Brass core provides durability without scratching rifling

Regular use prevents accuracy degradation caused by copper and lead buildup in the barrel grooves. Law enforcement armorers and competitive shooters rely on phosphor bronze brushes for maintenance routines that preserve zero and extend barrel life. The brush effectively removes stubborn fouling while being gentle enough for frequent cleaning without damaging the rifling or crown.
