KleenBore A179 Bore Brush .270/6.8mm/7mm Rifle Phosphor Bronze

The KleenBore A179 bore brush delivers thorough cleaning performance for .270, 6.8mm, and 7mm rifle calibers with phosphor bronze bristles that remove fouling without damaging barrel steel. This precision-manufactured cleaning tool features standard 8-32 threading for universal compatibility with most rifle cleaning rods and systems.

What Makes This Different

Phosphor bronze bristles provide the optimal balance between cleaning effectiveness and barrel protection, being harder than copper fouling but softer than barrel steel. Unlike steel brushes that can accelerate throat erosion, or nylon brushes that struggle with stubborn carbon buildup, phosphor bronze removes powder residue and metal fouling while preserving rifling integrity. The A179's precisely wound bristles maintain consistent contact pressure across the entire bore surface.
