What thread size does the Kleenbore A183 use, and will it fit my existing Australian cleaning rod?

The Kleenbore A183 features a standard American shotgun 5/16-27 thread. It is directly compatible with US-threaded rods like Kleenbore and Hoppe's, but if you are using a UK or European-pattern rod such as Parker-Hale, you will need a 5/16-27 thread adapter.

Can I use aggressive copper-removing solvents with this phosphor bronze brush?

No, you should avoid using heavy ammonia or copper-based solvents with the A183. While phosphor bronze stands up well to standard CLPs and nitro powder solvents, aggressive copper-dissolving chemicals will break down the bronze bristles over time.

How do the straight bristles on this 410 gauge brush perform against stubborn lead fouling?

The A183 utilizes straight, non-crimped phosphor bronze wire bristles with rounded tips rather than crimped wires. This design provides increased scrubbing stiffness and maximum surface contact to effectively lift lead fouling, plastic wad residue, and powder carbon without scratching your barrel.

.410 Bore Brush - KleenBore A183

The Kleenbore 410 Gauge Phosphor Bronze Bore Brush (Model A183) is a dedicated, manual bore-cleaning tool engineered specifically for .410 bore shotgun barrels. Sized to match an internal diameter of approximately 0.410 inches (10.4 mm), this brush utilizes straight, non-crimped phosphor bronze bristles with rounded tips to lift stubborn lead fouling, plastic wad residue, and powder carbon from bore walls and choked muzzles without scratching barrel steel. Fitted with a standard American shotgun 5/16-27 thread coupling, it directly attaches to standard cleaning rods to provide thorough scrubbing action for routine bench and field maintenance.

Key Features

Straight Phosphor Bronze Bristles: Constructed with non-crimped, straight bronze wire to provide rigid scrubbing resistance and consistent bore contact.
Bore-Safe Rounded Tips: Bristle ends are smoothed and rounded to prevent gouging or scratching the barrel interior during bidirectional cleaning strokes.
Durable Core Construction: Features an aluminium/brass twisted core with a steel/brass threaded coupling for structural integrity under manual pressure.
Residue Removal: Designed to dislodge plastic wad fouling, lead deposits, and nitro powder carbon.
Standard Thread Interface: Incorporates a standard American shotgun #5/16-27 thread pattern for compatibility with matching rods and adapters.

Who is the Kleenbore 410 Gauge Phosphor Bronze Bore Brush for?

.410 Gauge Shotgun Owners — Requires precise 0.410-inch (10.4 mm) bore-diameter bristles and a standard 5/16-27 thread coupling to scrub plastic wad fouling and lead deposits from single-shot, over/under, side-by-side, and lever-action .410 shotgun barrels without damaging barrel steel.

Less suitable for: Larger shotgun bores (such as 28, 20, or 12 gauge) or smaller rifle and handgun calibres (.17 to .35 caliber), which require gauge-specific or caliber-specific bore brushes; and cleaning routines utilizing aggressive copper- or ammonia-based bore solvents, which break down phosphor bronze and are better served by a solvent-resistant nylon bore brush.
