Nylon Bore Brush

Item:BBN

The nylon brush uses flexible, non-marring bristles that loosen debris without scratching the bore. Ideal for light cleaning, polymer-safe applications, and routine upkeep.

Product Features

  • 100% Solvent-Safe & Chemical Resistant: Unlike traditional bronze brushes that react and turn blue when exposed to aggressive copper solvents, these premium nylon bristles are completely chemical-resistant. Perfect for heavy-duty carbon and copper fouling removal.

  • Ultra-Gentle, Non-Scratch Protection: Engineered with high-density synthetic nylon, these bristles offer flexible yet vigorous scrubbing power. They are guaranteed 100% safe for all firearm barrels, ensuring zero scratches or marring to delicate rifling.

  • Excellent Bristle Memory & Durability: Features heavy-duty, thick-gauge nylon filaments that bend but easily snap back to their original shape. They resist flattening or shedding, outlasting standard brushes even after repeated rigorous use.

  • Rugged Construction & Premium Base: Built with a sturdy, multi-strand twisted core and a securely crimped threaded base (available in premium Aluminum/Brass). Designed to withstand heavy pushing and pulling without bending or snapping.

  • Full Range of Calibers Available: We offer a comprehensive selection of precisely cataloged sizes to fit everything from small-caliber rifles to heavy-gauge shotguns. Please refer to our specification chart below to select the perfect match for your firearm.
