BoreTech Proof Positive jag cal. 7mm

Bore Tech’s innovative Proof-Positive Rifle 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. Are your barrels PROOF-POSTIVE clean?

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 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.
