Bore Tech’s innovative Proof-Positive Rifle 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 Rifle 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,s and time.

Featuring a dual set of 4 contact rings* for added patch contact and cleaning, the Proof-Positive Rifle Patch Jags are precision machined to strict tolerances in order to work flawlessly and provide true, concentric pressure on the barrel surface. The first ring of each set is rounded in order to allow the jag to center itself in the chamber/bore and alleviates the possibility of damage. The three subsequent rings of each set have a squared face that grabs the patch keeping it in place. In addition, the relief space between the dual set of rings acts as an extra solvent reservoir by retaining clean/unused solvent and dispensing it before the second set of rings passes. Each rifle jag length is specifically determined based on the caliber and proper patch size necessary for cleaning. This prevents patches from bunching and jamming on the tip of the cleaning rod.
Each Proof-Positive Rifle Patch Jag features a reverse taper at the rear of the jag that provides a completely smooth, edge-free transition between the jag and rod when used with our Proof-Positive Bore Stix cleaning rods. The reverse taper prevents damage to the firearm’s crown by centering the jag and lifting the cleaning rod off the bottom of the barrel when pulling the rod back into the bore.
Finally, an answer to your question, “Is my barrel clean”?
Yes, it is PROOF-POSTIVE clean!
