It’s not just a brush it’s a Bore Tech Benchmark Brush! Bore Tech’s Benchmark Phosphor Bronze Bore Brushes are known for being the finest in the industry and set the benchmark for all other phosphor bronze brushes. With twice the amount of oversized bristles, double wound cores with looped ends and barrel safe studs these brushes provide long-lasting, safe and effective scrubbing action.

Bore Tech’s Benchmark Phosphor Bronze Bore Brushes are known as being the finest in the industry and set the standard for all other phosphor bronze brushes. This is due to the superior construction and engineered features incorporated into each and every brush.

Our premium Benchmark Bronze Brushes have twice the amount of phosphorous bronze bristles and each caliber has specifically tailored bristle diameters resulting in double the scrubbing action and faster cleaning.

Each 100% barrel safe, double wound bore brush core has a looped end eliminating the sharp cut ends found on many other low quality brushes. This attention to detail along with aircraft grade aluminum studs are all necessary to produce an effective, long lasting, high quality phosphor bronze bore brush for your rifle.

The .17 and .20 caliber rifle brushes are shortened 1 inch in length to lessen the necessary force required to push a brush through the bore. This helps diminish cleaning rod flex that can result in cleaning rod and barrel damage.

Bore Tech’s Benchmark Phosphor Bronze Rifle Bore Brushes are available in Single Packs and Three Packs ranging from .17 to .50 caliber.

We bet you never knew this much effort went into designing a quality brush!

Q: What do I clean my brushes with after use?

A: When using Bore Tech Cleaners, simply use warm water. We recommend rubbing the brushes between your palms while warm tap water flows over them.

Q: Why do my patches always turn blue when using your brushes with Eliminator Bore Cleaner?

A: Eliminator or any other cleaner that is designed to remove copper fouling will attack all bronze brushes and remove the copper within the bristles. To avoid this false indication of copper fouling in the bore, we recommend using our Proof-Positive Nylon Brushes with all copper removing cleaners.

Q: Do I have to unscrew my brushes before pulling my rod back through the bore to prevent damage to the crown?

A: We have been cleaning barrels since 1997 and have never had a crown compromised or accuracy affected by pulling a brush back through the bore. With our properly designed brushes and when used in a proper manner our brushes are 100% barrel safe. All of our barrels have been “shot out” well before a brush could have caused any damage.

Q: Will the core of the brush harm my barrel?

A: With our properly designed brushes and when used in a proper manner our brushes are 100% barrel safe.

Q: What thread sizes are your brushes and are they male or female ended?

A: All Bore Tech brushes are male ended and have the thread pitch listed under the Specifications Tab on the respective product page.
