Bore Tech Proof-Positive Rifle Patch Jags are designed to eliminate false copper fouling readings commonly caused by traditional brass jags when used with copper-removing cleaners.
Made from a proprietary brass-free alloy, these jags are 100% barrel safe, soft like brass, and strong enough to resist bending or snapping when used with tight patches.
▶ Why Proof-Positive Jags?
Traditional brass jags contain over 60% copper. When used with copper-removing solvents, they can leave blue staining on patches even when no copper fouling remains in the bore.
By removing brass from the cleaning process, Proof-Positive jags help shooters accurately determine when their barrel is truly copper free, saving patches, chemicals, and time.
▶ Key Features
- ✔ 100% brass free construction
- ✔ 100% barrel safe proprietary alloy
- ✔ Eliminates false copper fouling readings
- ✔ Precision machined for consistent performance
- ✔ Dual contact rings for superior cleaning
- ✔ Built-in solvent reservoir
- ✔ Reverse taper for smooth rod transition
▶ Improved Cleaning Performance
Each Proof-Positive Rifle Patch Jag features dual sets of four contact rings for enhanced patch contact and more effective cleaning.
The first ring is rounded to centre the jag, while the following squared rings grip the patch securely. The space between the rings retains clean solvent and releases it as the jag moves through the bore.
▶ Designed to Protect Your Firearm
The reverse taper creates a smooth, edge-free transition between the jag and cleaning rod.
This helps centre the jag and lift the rod away from the barrel when pulling it back, reducing the risk of crown damage.
Finally, a clear answer to the question: “Is my barrel clean?”
✔ Yes — it’s Proof-Positive clean.

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.
