Bore Tech innovative Proof-Positive rifle patch jags effectively eliminate the false indications of copper fouling commonly associated with traditional brass jags when using copper-removing cleaners. These jags are constructed from a proprietary alloy and undergo a secondary treatment process, ensuring they are entirely brass-free and safe for barrels. The alloy, while as soft as brass, offers exceptional tensile strength to prevent bending and snapping under the pressure of a tight patch. Traditional brass patch jags contain over 60% copper, which can result in a misleading blue copper fouling color on patches when using effective copper-removing cleaners, even if no copper is present in the bore. By eliminating brass components, shooters can accurately determine when a rifle bore is free of copper, thereby reducing the waste of patches, chemicals and time. The Proof-Positive rifle patch jags feature a dual set of four contact rings to enhance patch contact and cleaning efficiency. They are precision-machined to strict tolerances to ensure flawless operation and provide true, concentric pressure on the barrel surface. The first ring of each set is rounded to allow the jag to center itself in the chamber or bore, minimizing the risk of damage. The subsequent three rings have a squared face to secure the patch in place. Additionally, the relief space between the dual sets of rings serves as an extra solvent reservoir, retaining clean solvent and dispensing it before the second set of rings passes. Each rifle jag is specifically designed in length according to the caliber and appropriate patch size required for cleaning, preventing patches from bunching and jamming at the tip of the cleaning rod.
