Will this Kleenbore A175N nylon bore brush thread directly onto my standard Australian cleaning rod?

The A175N features a #3-48 smallbore male thread, which means it will not thread directly onto standard #8-32 centerfire rifle rods or shotgun rods without a separate smallbore thread adapter. You will need to ensure your cleaning rod is compatible with the #3-48 thread pitch or use an appropriate adapter before heading out to the bench.

Can I use aggressive copper-dissolving solvents with this nylon brush without damaging the bristles?

Yes, the heavy-duty black nylon bristles are fully compatible with aggressive ammonia-based copper-removing chemical solvents and will not break down. Unlike bronze brushes, the nylon construction eliminates false-blue copper contamination readings on your cleaning patches, giving you accurate feedback during deep cleaning.

What specific calibres are compatible with the Kleenbore A175N brush?

This brush is designed specifically for bore diameters between .170 inches and .200 inches, making it ideal for .17 HMR, .17 Hornet, .17 WSM, .17 Mach 2, and .177 air rifles. Using it in larger calibres like .224 results in inadequate wall contact, while using it in smaller sub-calibres can cause excessive resistance or bore jamming.

Does this cleaning accessory require any electrical compliance certifications for use in Australia?

No electrical compliance or SAA/RCM certifications are required for this product. The Kleenbore A175N is a completely non-powered, mechanical firearm maintenance accessory designed for manual cleaning out in the field or at the shooting bench.

.17 Caliber Bore Brush - KleenBore A175N

The Kleenbore .17 Caliber Nylon Bore Brush (Model A175N) is a dedicated smallbore maintenance tool designed to clean powder fouling and carbon deposits from rifle barrels without damaging rifling. Featuring heavy-duty, stiff black nylon bristles wound into a twisted wire core with a threaded brass coupling, this brush resists degradation from aggressive ammonia-based copper-removing solvents. Using nylon bristles prevents false-blue copper readings on cleaning patches during chemical soaking, making it a reliable tool for precision bore maintenance across smallbore rimfire, centerfire, and air rifle platforms.

Key Features

Chemical Solvent Resistance: Heavy-duty black nylon bristles do not react with or break down under aggressive ammonia-based copper solvents, eliminating false-blue copper indicators during cleaning.
Safe Rifling Contact: Stiff, high-density bristles scrub out stubborn carbon and powder fouling without scratching delicate smallbore rifling.
Dedicated Smallbore Threading: Integrated brass coupling features a male #3-48 smallbore thread designed specifically for dedicated small-calibre cleaning rods.
Durable Construction: Built with a secure twisted wire core to retain bristle density through repeated bore passes.

Who is the Kleenbore .17 Caliber Nylon Bore Brush for?

.17 HMR and .17 Hornet varmint and pest control shooters — Requires a bore brush sized for bore diameters between 0.170 in (4.32 mm) and 0.200 in (5.08 mm) that fits standard #3-48 smallbore cleaning rods and withstands harsh copper-stripping solvents during deep bore cleans.
.177 air rifle target shooters and enthusiasts — Utilises gentle nylon bristles across the 3.85-inch (97.8 mm) overall length to lift lead dust and residue from delicate airgun rifling without metal-on-metal barrel wear.

Less suitable for: Firearm bores measuring .224 inches (5.56 mm) and larger where undersized bristles lack adequate wall contact (requiring standard .22 calibre brushes), sub-calibres below 0.170 inches (4.32 mm) where the brush causes bore jamming, or standard #8-32 and 5/16-27 cleaning rods without a dedicated smallbore thread adapter.
