Bore Tech’s Proof-Positive Nylon Chamber Brushes are 100% chamber safe and set the benchmark for all other nylon chamber brushes. This is due to the superior construction and engineered features that are incorporated into each and every brush.

Unlike phosphor bronze bristled brushes, our premium Proof-Positive Nylon Chamber Brushes are strongly recommend when using fast acting copper removing cleaners such as our Eliminator Bore Cleaner or Cu+2 Copper Remover. These brushes are not affected by copper removing cleaners and will eliminate blue patches and the false indication of copper fouling that is associated with traditional phosphor bronze brushes.

All Proof-Positive Nylon Chamber Brushes have twice the amount of extra ridged nylon bristles and each caliber has specifically tailored bristle diameters resulting in double the scrubbing action and faster cleaning.

Each non brass, double wound 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 nylon chamber brush for your rifle.

Bore Tech’s Proof-Positive Nylon Chamber Brushes are available in Single Packs for both the .223/5.56mm AR-15 and .308/7.62mm AR-10.

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: 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.

Well made and effective 5 of 5 stars

I like nylon brushes over bronze, how much any brush helps with black powder is debatable but I use them and don't like metal brushes in my bores. These seem well made and do the job well.
