KleenBore A180N 7.62mm/.30/.308 Cal/300 Blackout Rifle Bore Brush - Nylon Bristles, 8-32" Thread

The KleenBore A180N is a nylon-bristle bore brush built for serious rifle cleaning. If you shoot .30 caliber, 7.62mm, .308 Winchester, or .300 Blackout—whether you're breaking in a new barrel, maintaining a duty rifle, or keeping your long-range gun in fighting condition—this brush tackles fouling without compromise. Nylon bristles strike the balance many shooters want: stiff enough to scrub out carbon and copper, yet gentle enough that you can run it repeatedly without worrying about bore damage.

Kleen-Bore designed these brushes with density and durability in mind. The heavy-duty bristles are packed thick and won't fray or shed after a few cleaning sessions, which matters when you're running patches and solvent through the bore a dozen times over. The brush threads onto any cleaning rod with standard 8-32" threads—the universal interface on most rifle cleaning kits—so you're not buying a whole new setup just to add a quality brush to your bench.

Made in the USA and trusted by shooters who take bore maintenance seriously, this is the kind of tool that stays in your range bag or cleaning kit for years. It's the unglamorous stuff that keeps your rifle accurate and reliable, without the markup or marketing flash.

Frequently Asked Questions

Will this brush work with my cleaning rod?

Yes, if your cleaning rod has the standard American 8-32" thread. This is the universal thread on most rifle cleaning kits and rods. If you're unsure, check the thread on your current rod or brush—if that works, this one will too.

Can I use this for .308 Winchester, .300 Blackout, and 7.62mm?

Yes. This brush is sized for all .30 caliber variants, including .308 Winchester, .300 Blackout, and 7.62mm NATO. They all share the same bore diameter.

Are nylon bristles as effective as bronze or brass?

Nylon bristles are stiffer and more durable than softer materials, making them effective for tough fouling and carbon removal. They're recommended by major firearms manufacturers for general bore cleaning and won't damage modern rifle barrels.

How long does this brush last?

With proper care and typical use, the dense nylon bristles resist fraying and shedding, so you can expect years of reliable performance from one brush.
