.40cal / 10mm Proof Positive Pistol Jag
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.
Each Proof-Positive Pistol Patch Jag is precision machined to strict tolerances in order to work flawlessly and provide true, concentric pressure on the barrel surface.
Our Proof-Positive Pistol Patch Jags prevent damage to the firearm’s crown when pulling the rod back into the bore by utilizing a completely smooth, edge free transition between the jag and rod when used with either our Proof-Positive Bore Stix or V-Stix cleaning rods.
