Product Description
Bore Tech's Proof-Positive Rifle Jag in .20 caliber is engineered to deliver accurate, copper-free cleaning results. Built from a proprietary, 100% brass-free alloy, it prevents the false blue copper indication often seen with traditional brass jags when using copper-removing solvents. Precision machining and a dual set of four contact rings maximize patch engagement and maintain concentric pressure on the bore. A relief space between the ring sets acts as a solvent reservoir for efficient delivery, while the reverse taper at the rear provides a smooth transition to the cleaning rod and helps protect the firearm's crown—especially when paired with Proof-Positive Bore Stix cleaning rods. The .20 caliber size and 5/40 thread pitch ensure a proper fit with compatible rods and patch sizes.
