BoreTech Kartáč bronzový .338 (3 ks)
Bronze Brush .338 (3 pcs)
BoreTech (USA)
The bronze brush from the American brand BoreTech represents the pinnacle among cleaning brushes for rifles. It is designed with an emphasis on performance, safety, and durability. Unlike ordinary brushes, this model contains double the amount of phosphor-bronze bristles, with the diameter and distribution of the bristles precisely optimized for a specific caliber.
The brush features a double-wound core with a closed loop, eliminating the risk of damage to the barrel bore from sharp ends. Thanks to the aerospace-grade aluminum thread, it is ideal for long-term use without corrosion or wear.
The perfect choice for anyone who takes firearm maintenance seriously – whether competitive shooters, hunters, or professionals.

Questions and Answers:
- What should I use to clean the brushes after use?
- If you are using BoreTech cleaning products, warm water is sufficient. We recommend rubbing the brush between your palms under warm running tap water.
- Why do my cleaning patches always turn blue when using the brush with Eliminator cleaner?
- Eliminator, like other products designed to remove copper fouling, reacts with the bronze brush and begins stripping copper from the bristles. To avoid a false indication of copper fouling in the bore, we recommend using BoreTech Proof-Positive nylon brushes

- Do I need to unscrew the brush before pulling the rod back through the barrel to avoid damaging the muzzle?
- We have never observed any muzzle damage or loss of accuracy from passing the brush back through the barrel. BoreTech brushes are well designed and, when used correctly, are 100% safe for the bore. The barrel will wear out long before the brush could cause any damage.
