Will the KleenBore A188N nylon brush react with aggressive copper-removing solvents?

No, unlike phosphor bronze or brass brushes, the heavy-duty black nylon bristles do not react with ammoniated chemical bore cleaners or copper solvents. This prevents false copper fouling indicators such as blue or green patch staining during your cleaning routine.

What cleaning rods are compatible with the #8-32 thread pattern on this .22 handgun brush?

The A188N features a standard American #8-32 male thread that mounts directly to standard pistol cleaning rods widely used in Australia, such as KleenBore, Pro-Shot, and Hoppe's. Please note it will not mount to shotgun rods using #5/16-27 threads or European rods using M3 or M4 threads unless you use a conversion adapter.

Is this nylon brush suitable for removing severe lead buildup or baked-on carbon in my .22 pistol barrel?

While the A188N is excellent for routine maintenance, light-to-medium powder fouling, and applying liquid solvents, it is not optimized for heavy deposits. For severe lead buildup or baked-on carbon ring removal, a phosphor bronze brush or a mechanical scraper suits the task much better.

.22 Nylon Bore Brush - KleenBore A188N

The Kleenbore .22 Handgun Nylon Bore Brush (Model A188N) is a dedicated mechanical cleaning accessory engineered for .22 calibre (5.6mm) handgun barrels. Featuring heavy-duty, stiff black nylon bristles on a twisted core wire, this non-marring tool removes powder residue and carbon fouling without scratching match-grade rifling or specialized bore coatings. Because nylon does not chemically react with ammoniated bore cleaners or copper-removing solvents, it eliminates false copper-fouling indicators during deep bore maintenance.

Key Features

Chemical-Resistant Nylon Bristles: Stiff nylon construction resists degradation from aggressive bore solvents and foams, preventing false blue/green chemical reactions.
Non-Marring Scrubbing Action: Cleans pistol and revolver bores without the risk of micro-abrasions to delicate barrel rifling.
Handgun-Specific Profile: Sized to an overall length of approximately 2 inches (~50 mm) for smooth cycling through short pistol barrels.
Standard Thread Mounting: Fitted with an industry-standard #8-32 male thread for broad compatibility with standard handgun cleaning rods.

Who is the Kleenbore .22 Handgun Nylon Bore Brush for?

ISSF .22 pistol competitors — requires a non-marring bore brush that safely scrubs match-grade 5.6mm barrels without degrading precision rifling during frequent solvent-based cleaning sessions.
Australian target pistol shooters — needs a handgun bore brush with an industry-standard #8-32 male thread and a compact ~50 mm total length to match standard pistol cleaning rods for routine club maintenance.

Less suitable for: Firearm bores smaller than .22 calibre (such as .17 or .177), calibres .38/9mm and larger, cleaning rods utilizing #5/16-27 shotgun or M3/M4 metric threads without an adapter, or heavy lead and baked-on carbon buildup, which requires a stiffer phosphor bronze bore brush or stainless steel mechanical scraper.
