Breakthrough Clean Technologies® Nylon Bristle Bore Brush — 20 Gauge, Retail Packaging (BT-20GNBB • BT20GNBB • UPC 852712005640) Gentle on bores, tough on fouling. The Breakthrough Clean Technologies Nylon Bristle Bore Brush for 20-gauge shotguns delivers reliable, non-marring scrubbing power to lift powder residue, plastic wad fouling, and light carbon without risking your barrel’s finish. Purpose-built for routine maintenance, this brush pairs perfectly with your favorite solvent and cleaning rod to keep field and sport shotguns cycling smoothly and patterning true—season after season. Why Choose a Nylon Bore Brush for 20 Gauge? Non-marring scrubbing: Nylon bristles dig into residue while staying gentle on chrome-lined, blued, and Cerakote®-finished barrels when used as directed. Solvent friendly: Nylon stands up to modern bore cleaners (including aggressive carbon removers) better than some natural fibers. Plastic wad fouling control: Helps loosen stubborn plastic streaks left by shotcup wads—common in high-volume clay or bird loads. Consistent diameter & density: Quality construction maintains uniform contact with the bore for efficient, repeatable cleaning passes. Everyday maintenance tool: Ideal for post-hunt wipe downs and between-station touch-ups for trap, skeet, and sporting clays. Key Features at a Glance Gauge: 20 Gauge Bristle Material: Nylon (non-marring, solvent resistant) Core/Stem: Rigid, durable stem for stable push/pull strokes Threading: Shotgun-standard 5/16"-27 (typical; verify your rod’s thread spec) Packaging: Retail packaging for easy storage and peg display Brand: Breakthrough Clean Technologies® Model / SKU: BT-20GNBB / BT20GNBB UPC: 852712005640 Pro Tip: For efficient cleaning, alternate a solvent-soaked patch, nylon brush scrubs, and dry patches until they come out clean. Finish with a light oil to protect the bore. Performance You’ll Notice Faster clean-up: Nylon bristles maintain their shape under pressure, helping you clear residue with fewer passes. Finish protection: A safer choice for routine scrubbing when you want to minimize abrasive wear on polished bores. Better patterns over time: Keeping plastic and powder fouling in check helps preserve consistent velocities and POI. Ideal Use Cases Upland & waterfowl shotguns cleaned right after the hunt Sporting clays, trap, skeet guns between rounds and after high-volume days Home bench maintenance for 20-gauge collections Travel/range kits where a solvent-tolerant, gentle brush is a must How to Use (Quick Guide) Unload and verify clear. Remove barrel per manufacturer instructions. Apply solvent. Run a wet patch to soften fouling. Scrub: Attach the 20-ga nylon brush and make full-length passes from chamber to muzzle. Patch dry: Follow with dry patches until clean. Protect: Finish with a light oil patch (avoid excess in the chamber before shooting). Always follow your firearm manufacturer’s guidance for disassembly and cleaning. Care & Maintenance Rinse & dry the brush after use to remove solvent and residue. Store straight to prevent bristle deformation. Replace when bristles look matted, shortened, or splayed for best performance. Thread care: Add a drop of oil to threads occasionally to prevent galling on the rod. Compatibility Notes Designed for 20-gauge shotgun bores. Rods/handles typically use 5/16"-27 shotgun threads; confirm your rod before purchase or use a thread adapter if needed. Safe for common finishes when used as directed; spot test unusual coatings and avoid prolonged soaking of the brush in harsh chemicals.

A: Nylon is generally compatible with aggressive solvents, but follow the solvent maker’s instructions and avoid prolonged soaking of the brush. Q: How often should I replace the brush? A: Replace when bristles lose stiffness or deform; performance drops as the brush wears. Q: Is it safe for chrome-lined or Cerakote® bores? A: Yes—used as directed, nylon is non-marring and safe for common finishes. Always test on a small, inconspicuous area first.
