Breakthrough Clean BT4445PBBB Phosphorus Bronze Bore Brush - Precision Gun Cleaning Tool$3.49
Availability: In Stock
Keeping your .270 or 7mm rifle clean and accurate starts with the right bore brush. The Kleen-Bore bore brush is engineered specifically for these calibers to remove fouling and powder residue safely and effectively without compromising your barrel's rifling. Built with phosphor bronze bristles and American standard threads, this brush is a no-nonsense cleaning tool designed for shooters who understand that barrel maintenance directly affects precision and reliability downrange.
The straight-wire bristle design—not crimped—delivers more aggressive cleaning power than competitor brushes, while the rounded bristle tips protect your bore from damage. The brush stays thick and stout under cleaning pressure, resisting the bending and fraying that can happen with thinner alternatives. Phosphor bronze is the material of choice for rifle bore cleaning because it's tough enough to scrub fouling but soft enough to never scratch the precision rifling that makes your rifle shoot straight.
Whether you're breaking in a new barrel, cleaning between range sessions, or doing a deep maintenance pass after hunting season, this brush is a workhorse accessory that belongs in every rifleman's cleaning kit. Made in the USA with standard #8-32 threads to fit your standard cleaning rod.

Yes, if your cleaning rod has American standard #8-32 threads. This is the universal thread size for rifle bore brushes and cleaning rods, so it will fit standard kits from all major manufacturers.
Phosphor bronze is softer than steel, which means it cleans aggressively but won't scratch or damage your rifle's rifling. Steel brushes can leave marks on precision bores and are much riskier for long-term barrel care.
Use it whenever you clean your rifle—after range sessions, hunting trips, or whenever you run a cleaning rod through the bore. Regular brushing keeps fouling from building up and maintains the rifle's accuracy.
No, this is the brush only. You'll need a cleaning rod with #8-32 threads to use it. Most standard rifle cleaning kits include compatible rods.
