Breakthrough Clean Technologies® Nylon Bristle Bore Brush — .40 Cal / 10mm | Retail Packaging | Model BT-40NBB | UPC 852712005824

Give your .40-caliber and 10mm handguns the fast, safe scrub they deserve. The Breakthrough Clean Technologies Nylon Bristle Bore Brush (.40 Cal / 10mm) combines solvent-resistant nylon filaments with a precision-wound core for uniform 360° contact through your bore. It attacks powder fouling, carbon, and stubborn residue without scratching the steel—ideal for routine maintenance on defensive pistols, competition guns, and range workhorses. Packaged in retail packaging to keep bristles clean in your range bag, the BT-40NBB is the dependable brush you’ll reach for after every session.

Why Choose Nylon for .40 Cal and 10mm?

• Non-marring, bore-safe cleaning: Nylon bristles won’t gouge or polish the rifling, making them perfect for carbon steel, stainless, and nitride-treated barrels.

• Solvent-ready fibers: Chemical-resistant nylon stands up to aggressive carbon removers and copper solvents so you can let chemistry do the heavy lifting.

• Consistent 360° contact: Dense filament pack and an even core wind deliver uniform pressure for efficient scrubbing from breech to muzzle.

• Durable, long-lasting build: Resists deformation over repeated passes—great for high-round-count shooters and instructors.

• Clean, organized storage: Retail packaging protects bristles from dust, oil, and shop debris.

Optimized for Popular Platforms

Perfect for .40 S&W and 10mm Auto pistols—including striker-fired duty guns, competition builds, and classic hammer-fired platforms—as well as pistol-caliber carbines that use .40/10mm barrels. Keep patterns tight, groups consistent, and extraction smooth with regular nylon brushing.

Faster, Cleaner Results

Nylon filaments flex into micro-crevices and machining marks to lift fouling without scuffing rifling or crowns. For best results, pre-wet the bore with solvent, make several smooth, full-length strokes, and follow with dry patches. Finish with a lightly oiled patch for a uniform, corrosion-resistant film.

How to Use (Best Practices)

1. Unload and verify safe. Remove the magazine and check the chamber.

2. Pre-wet the bore. Apply a quality solvent with a patch or mop and allow a short dwell time.

3. Brush breech to muzzle. Use steady, full-length strokes; avoid reversing direction mid-bore.

4. Repeat as needed. Nylon tolerates robust solvents—reapply for heavy deposits.

5. Patch clean & protect. Run dry patches until clean, then a light oil patch before storage.

Pro Tip: Keep two brushes—one dedicated to solvent scrubbing and another for quick post-range touch-ups. Rotation preserves filament stiffness and extends service life.

Ideal For

• Carry & duty pistols in .40 S&W

• 10mm hunting/field pistols exposed to dust, moisture, and temperature swings

• USPSA/IPSC/IDPA competitors cleaning between stages or practice blocks

• Club ranges & instructors servicing multiple handguns

Care & Maintenance

• Rinse bristles in warm water after heavy solvent use; shake or towel-dry.

• Store inside the retail sleeve or a sealed pouch to keep debris off the filaments.

• Replace when bristles look splayed, shortened, or noticeably softened.

Specifications

Compatibility Notes

• Confirm your cleaning rod’s thread size; add an adapter if needed.

• Safe with common CLP, carbon cutters, and copper solvents—follow chemical manufacturer instructions.

• For extreme lead or copper, alternate a few passes with a bronze brush, then return to nylon for routine care.
