Kleen-Bore
Keeping your rifle bore clean is non-negotiable if you want reliable accuracy and barrel longevity. The KleenBore A178N bore brush for 25/243 cal/6mm/6.5mm rifles is a workhorse cleaning tool built to tackle fouling and buildup without cutting corners. Fitted with heavy-duty nylon bristles and the standard 8-32" thread found on most rifle cleaning rod setups, this brush is made in the USA and designed to handle serious scrubbing jobs—whether you're breaking in a new barrel, maintaining a hunting rifle, or running a high-round-count range day.
Nylon bristles offer real advantages for centerfire rifle cleaning. They're stiff enough to dislodge powder residue, copper fouling, and carbon without the risk of bore damage that softer materials can sometimes cause. The dense bristle construction means more contact with the bore walls, so you're not wasting strokes on ineffective passes. This is especially useful in the magnum and mid-range calibers like the 243 Winchester and 6mm Creedmoor, where precision cleaning pays dividends in shot consistency.
If you run multiple rifles in these common calibers, having a dedicated brush on hand means faster cleaning sessions and one less variable between your guns. Pair it with a quality rod and solvent, and you've got a maintenance setup that works.
| Caliber Fit | 25/243 cal, 6mm, 6.5mm |
| Thread Size | 8-32" |
| Bristle Material | Nylon |
| Country of Origin | USA |
The KleenBore A178N uses a standard American 8-32" thread, which is the common size for most rifle cleaning rods. Check your rod's thread size before ordering—if it's 8-32", you're good to go.
This brush is designed for 25/243 cal, 6mm, and 6.5mm rifle bores. It will work on any centerfire rifle in those caliber ranges, including hunting rifles, target rifles, and precision platforms.
Nylon bristles are stiff enough for serious fouling removal but won't score or damage modern rifle bores. They're the recommended choice by many firearms manufacturers for routine bore cleaning without risk of wear.
Attach it to your cleaning rod, apply bore solvent, and run it back and forth through the bore with steady, controlled strokes. The heavy-duty bristles do the work—you don't need to force it. Clean until the patches come out clean, then follow up with a final dry patch and a light coat of bore protectant.
