Kleen-Bore
The KleenBore A186 12 gauge bore brush is a shotgun cleaning essential built to cut through powder residue and fouling without compromising barrel integrity. Unlike cheaper brushes with crimped bristles that bend under pressure, this phosphor bronze brush features straight wire construction that stays rigid as you work it down the bore—giving you the scrubbing power you need without having to baby your tool. The rounded bristle tips are gentle on your shotgun's interior surfaces while still delivering effective cleaning action, making this a smart choice for shooters who care about maintaining their equipment properly.
Shotgun shooters know that bore brushes take a beating. This Kleen-Bore brush is engineered to withstand the back-and-forth motion required to strip stubborn residue from your barrel. Phosphor bronze won't damage the inside of your shotgun barrel, so you can clean with confidence whether you shoot clay, buckshot, or slugs. The threads match the American standard 5/16-27 connection, so it'll work with most shotgun cleaning rods and patches you already have on hand.
Made in the USA, the A186 reflects Kleen-Bore's long reputation for no-nonsense cleaning tools. This isn't a disposable brush—it's designed to be durable enough for regular use across multiple shooting seasons. Whether you're breaking in a new shotgun or maintaining a reliable hunting gun, having a quality bore brush in your cleaning kit is the foundation of keeping your barrels in top condition.
| Gauge | 12 | |
| Brush Type | Bore brush | |
| Material | Phosphor bronze | |
| Thread Size | American standard 5/16-27 | |
| Bristle Type | Straight wire with rounded tips | |
| Manufacture | Made in USA |
The KleenBore A186 uses American standard 5/16-27 threads, which is the common connection for shotgun cleaning rods. Check your rod's thread size to confirm compatibility.
Yes. Phosphor bronze is specifically chosen for bore brushes because it's softer than steel barrel material—it effectively removes fouling without scratching or damaging the rifling and surfaces inside your barrel.
This is a 12 gauge brush. It's sized specifically for 12 gauge shotgun bores and should not be forced into other gauges, as it may damage the barrel or get stuck.
The straight wire bristles and rounded tips are engineered to stay rigid under cleaning pressure while protecting your barrel. Crimped bristles bend too easily, reducing cleaning effectiveness and requiring you to work harder—and potentially rougher—to get the same results.
