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.\u003c\/p\u003e\u003ch3\u003eProduct Highlights\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e100% brass-free alloy eliminates false copper fouling indications\u003c\/li\u003e\n\u003cli\u003eDual 4-ring design boosts patch contact and consistent bore pressure\u003c\/li\u003e\n\u003cli\u003eBuilt-in solvent reservoir between ring sets for optimized cleaning\u003c\/li\u003e\n\u003cli\u003eReverse taper protects the crown and ensures smooth rod-to-jag transition\u003c\/li\u003e\n\u003cli\u003e.20 caliber with 5\/40 thread pitch for precise compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eProduct Type: Proof-Positive Rifle Jag\u003c\/li\u003e\n\u003cli\u003eCaliber: .20 Cal\u003c\/li\u003e\n\u003cli\u003eThread Pitch: 5\/40\u003c\/li\u003e\n\u003cli\u003eA (inches): 0.155\u003c\/li\u003e\n\u003cli\u003eA (inches): 2.000\u003c\/li\u003e\n\u003cli\u003eBrand: Bore Tech\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number: BORBTAJ2000\u003c\/li\u003e\n\u003cli\u003eUPC: 667739980289\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
