Cleaning .17 and .177 caliber rifles—whether you shoot centerfire varmint rounds or air rifles—demands a bore brush that won't compromise bore integrity. The KleenBore A175 phosphor bronze bore brush is purpose-built for precision smallbore cleaning, with straight-wire bristles engineered to scour fouling and powder residue without harming the delicate rifling in these tight bores. The #3-48 thread matches standard smallbore rod connections, making it a direct fit for your existing cleaning rod setup.
Phosphor bronze is the material of choice here because it's hard enough to cut through stubborn carbon and copper buildup, yet softer than steel—meaning it won't score or peen the bore walls. The brush is constructed with a stout, thick core that resists bending under the pressure of aggressive scrubbing, so you can work the bore thoroughly without worrying about the brush collapsing or deforming inside the barrel.
The bristles feature rounded tips by design, a detail that matters more than it sounds. Rounded ends distribute cleaning pressure evenly across the bore surface, reducing the risk of wire marks while maintaining effective contact with the rifling. If you're serious about maintaining the accuracy and longevity of a precision .17 rifle or air gun, this is the kind of thoughtful engineering that shows KleenBore understands the job.

Frequently Asked Questions
Will this brush fit my .17 HMR rifle?
Yes. The KleenBore A175 is designed for .17 and .177 caliber rifles with #3-48 threads, which is the standard smallbore rod connection. Confirm your cleaning rod uses #3-48 male threads before purchase.
Can I use a phosphor bronze brush on an air rifle barrel?
Absolutely. Phosphor bronze is safe for air rifle bores and is actually preferred because it cleans effectively without the risk of damaging the softer steel often found in air gun barrels.
Why straight bristles instead of crimped?
Straight wires maintain their rigidity better during aggressive scrubbing and deliver more consistent contact with the bore surface, making them more effective at cutting through stubborn fouling while keeping bristle alignment stable.
What's the difference between phosphor bronze and steel brushes?
Phosphor bronze is softer than steel, meaning it cleans powerfully without the risk of scoring or peening bore walls. Steel brushes are more aggressive and better suited to heavily fouled barrels, but phosphor bronze is the standard for routine precision rifle maintenance.
