Product DescriptionBore Tech Proof-Positive Nylon Rifle Bore Brushes are engineered for safe, effective bore cleaning without the risk of barrel damage. This three-pack in .243 caliber / 6 mm features male 8/32 threads and a 2.5-inch brush length for reliable fit and reach. Each brush uses a non-brass, double-wound alloy core with a looped end and an aircraft-grade aluminum stud for strength and longevity. Extra-rigid nylon bristles are tailored by caliber to deliver twice the scrubbing action, and the non-brass construction ensures compatibility with fast-acting copper removers without producing misleading blue patches.Ideal for use with copper-removing cleaners, these brushes eliminate false indications of copper fouling that can occur with traditional phosphor bronze brushes. Clean faster, protect your bore, and stay proof-positive that your rifle is truly free of copper fouling.Product Highlights100% barrel-safe Proof-Positive design with non-brass core and threadsCaliber-specific, extra-rigid nylon bristles for enhanced scrubbing powerMale 8/32 threads and 2.5-inch brush length for secure fit and reachLooped-end, double-wound alloy core with aircraft-grade aluminum studOptimized for copper-removing cleaners-no false blue patch readingsSpecsProduct Type: Nylon Rifle Bore BrushCaliber: .243 / 6 mmPack Quantity: 3Thread Size: Male 8/32Brush Length: 2.5 inchesCore: Non-brass, double-wound alloy with looped endStud: Aircraft-grade aluminumBristle Material: NylonUPC: 667739666633Manufacturer Part Number: BORBTNR06003Brand Name: Bore TechDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
