Bore Tech Proof-Positive Rifle Patch Jag – .338 Cal (8/32 Thread)

The Bore Tech Proof-Positive Rifle Patch Jag in .338 Caliber is a precision-engineered cleaning accessory designed to eliminate the false copper fouling readings that plague traditional brass jags. If you’ve ever wondered whether your bore is truly clean or if your cleaner is just reacting with a brass jag, this is the solution.

Why Proof-Positive?

Traditional brass jags contain over 60% copper in their composition. When paired with effective copper-removing solvents, this causes patches to show a blue color — even when your barrel is already clean. Bore Tech’s Proof-Positive jags are crafted from a proprietary, 100% brass-free alloy with a secondary treatment process that eliminates false readings entirely. The result: you know exactly when your bore is truly copper-free, saving you patches, solvents, and time.

Key Features

• 100% Brass-Free & Barrel Safe: Proprietary alloy is as soft as brass but offers exceptional tensile strength to resist bending and snapping under tight-patch pressure.
• Dual Set of 4 Contact Rings: Precision-machined dual ring sets deliver true, concentric pressure on the bore surface for maximum patch contact and cleaning efficiency.
• Self-Centering Rounded Leading Rings: The first ring of each set is rounded to center the jag in the chamber and bore, reducing the risk of damage during insertion.
• Squared Trailing Rings: The three subsequent rings in each set feature a squared face that grips the patch firmly and keeps it in place throughout the stroke.
• Integrated Solvent Reservoir: The relief space between the dual ring sets retains fresh solvent and dispenses it ahead of the second ring set, ensuring consistent solvent coverage throughout the cleaning pass.
• Caliber-Specific Length: Each jag is sized specifically for its caliber and the appropriate patch size, preventing patches from bunching or jamming on the rod tip.
• Reverse Taper Design: The rear reverse taper provides a smooth, edge-free transition between jag and rod — ideal for use with Bore Tech Proof-Positive Bore Stix rods — and centers the jag to protect your firearm’s crown during rod retrieval.
