KleenBore A191 Phosphor Bronze Bore Brush .40/.41/10mm 8-32 Thread

The KleenBore A191 bore brush delivers thorough cleaning for .40 S&W, .41 caliber, and 10mm handgun barrels with precision-engineered phosphor bronze bristles. This cleaning brush removes fouling and residue that standard patches often leave behind.

What Makes This Different

Phosphor bronze bristles provide the optimal balance between effective cleaning power and barrel protection. Unlike steel brushes that can cause wear over time or nylon brushes that lack sufficient scrubbing ability, phosphor bronze removes stubborn fouling without damaging rifling. The 8-32 thread standard ensures compatibility with most cleaning rod systems.
