Bore Tech’s Proof-Positive Nylon Bore Brushes are 100% barrel safe and set the benchmark for all other nylon 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 Bore Brushes are strongly recommend when using fast acting copper removing cleaners such as our Eliminator Bore Cleaner or Cu+2 Copper Remover. This is due to the fact that traditional phosphor bronze brushes contain over 90% copper in their composition and will turn patches blue when in contact with most copper removing cleaners. With barrel safe, non-brass cores and threads Bore Tech’s Proof-Positive Nylon Bore 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 Bore 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 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 Proof-Positive Nylon Rifle Bore Brushes are available in Single Packs and Three Packs ranging from .17 to .50 caliber.

Eliminate the confusion and be 100% Proof-Positive that your rifle barrels are free of copper fouling.

Bore Tech Information

Proof Positive Benefits?

Bore Tech’s Proof-Positive feature is a major innovation in firearm cleaning, designed to eliminate false positive indications of copper fouling. Traditional cleaning jags and loops are typically made from brass, which contains copper. When using ammonia-based copper solvents, these brass components can react chemically, producing a blue or green color in the solvent. This color change often misleads shooters into believing there is still copper fouling in the bore when, in reality, the reaction is coming from the jag itself. Bore Tech’s Proof-Positive jags and loops are made from a proprietary, brass-free alloy that eliminates this problem. This means any color change in the solvent is a true indication of copper fouling in the bore, allowing for more accurate and reliable cleaning.

The Proof-Positive feature is particularly beneficial for shooters who demand precise barrel maintenance, such as competitive marksmen, hunters, and gunsmiths. By removing the interference caused by brass jags, Bore Tech ensures that users don’t waste time and solvent chasing false copper indications. Additionally, Proof-Positive jags and loops are precision-machined for a perfect patch fit, ensuring thorough bore contact and more effective cleaning. This leads to less solvent waste, reduced cleaning time, and a properly maintained barrel, which ultimately enhances firearm accuracy and longevity. For anyone serious about firearm care, Proof-Positive technology is a game-changer, providing a smarter and more efficient cleaning process.

Which Rod Size

When choosing a Bore Tech cleaning rod for your rifle, you need to consider the barrel length and action type to ensure you get the right rod length. A good rule of thumb is to select a rod that is at least 6-8 inches longer than your rifle's barrel to accommodate the action and allow for full stroke cleaning. For bolt-action rifles, measure from the chamber to the muzzle and add extra length for comfortable use. For AR-style rifles, you may need an even longer rod due to the upper receiver's design. Bore Tech rods typically come in lengths ranging from 36 inches to 50 inches, so selecting the right one depends on your rifle’s specifications.
