Bore Tech Proof-Positive Rifle Jag

The Bore Tech® Proof-Positive Rifle Jag is a professional-grade cleaning jag, trusted by experienced armorers and civilian shooters across the globe. Designed to eliminate the risk of a false indication of copper fouling, this jag boasts a proprietary alloy housing with a dual set of 4 contact rings, precision-machined to provide true, concentric pressure on the barrel surface for a consistent and reliable clean. 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, while the other rings feature a squared face to keep patches securely in place for a more thorough clean. The reverse taper at the rear of the jag 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. Compatible with most threaded cleaning rods.
