Bore Tech’s innovative Proof-Positive Pistol Patch Jags eliminate the false indication of copper fouling that is common with all traditional brass jags when using copper removing cleaners. Constructed from a proprietary alloy and engineered to provide superior cleaning, these jags set the standard for effective, non-brass, 100% barrel safe jags.
Bore Tech’s innovative Proof-Positive Pistol Patch Jags eliminate the annoying false indication of copper fouling that is common with all traditional brass jags when using copper removing cleaners.
All Proof-Positive Pistol Patch Jags feature a proprietary alloy and secondary treatment process, making them 100% brass free and 100% barrel safe. This alloy is as soft as brass but boasts an exceptional tensile strength to prevent bending and snapping under the force of a tight patch.
Traditional brass patch jags are over 60% copper in their composition. When using effective copper removing cleaners this results in a blue copper fouling color on your patches when no copper is present in the bore. By eliminating brass accessories, shooters can effectively determine when a rifle bore is truly copper free and reduce wasted patches, chemical and time.
