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.

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.

FAQ
Q: Why choose nylon over bronze?
A: Nylon is gentler on finishes and highly solvent resistant, making it excellent for routine cleanings. Bronze offers more bite for heavy fouling—many shooters keep both.
Q: Will this fit my cleaning rod?
A: Most shotgun rods use 5/16"-27 threads. Verify your rod spec; adapters are widely available if needed.
Q: Can I use it with copper or ammonia-based solvents?
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.
