KleenBore A187 10 Gauge Shotgun Bore Brush - Phosphor Bronze Bristles, 5/16-27 Thread

The KleenBore A187 10 gauge shotgun bore brush is built for shooters who demand thorough, effective cleaning without cutting corners—or cutting bores. If you run a 10 gauge and want to keep your barrel in fighting trim, a quality bore brush matters. This one uses phosphor bronze bristles engineered to scrub away powder fouling and carbon buildup safely, whether you're breaking in a new gun or maintaining a trusted hunting partner after a long season in the field.

What sets this brush apart is its construction: straight (not crimped) bristles that stay rigid as they work down the bore, giving you real scrubbing power instead of flexing and folding on you mid-stroke. The rounded bristle tips and phosphor bronze material are chosen specifically to clean hard without marring your bore's rifling or choke. You get the mechanical advantage of a stiff brush backed by a metal that won't scratch steel—a difference you'll feel and see in your bore condition over time.

The A187 threads to the standard American shotgun specification (5/16-27), so it'll fit your existing cleaning rod setup. Made in the USA by Kleen-Bore, a company that's been making gun cleaning tools since serious shooters first realized that a clean barrel shoots cleaner. This is straightforward, no-nonsense bore maintenance for hunters, clay shooters, and anyone who believes preventive care beats bore erosion.

Frequently Asked Questions

Will this brush fit my 10 gauge shotgun cleaning rod?

Yes, if your rod uses standard American shotgun threads (5/16-27). The A187 is threaded to that specification. If you're unsure of your rod's thread size, check the rod's packaging or contact the manufacturer.

Can I use a phosphor bronze brush on my shotgun barrel without damaging it?

Phosphor bronze is chosen specifically for barrel cleaning because it's softer than steel bore metal—it scrubs fouling effectively without scratching or eroding the rifling. The rounded bristle tips add another layer of bore-safe design.

What's the difference between this straight-bristle brush and a crimped one?

Straight bristles maintain their stiffness as you push the brush down the bore, giving you consistent scrubbing pressure and better fouling removal. Crimped bristles tend to flex more easily, reducing cleaning efficiency.
