Cleaning jags are constructed with machined aluminum components, which do not react with ammonia-based solvents as brass parts occasionally do. This ensures that they do not produce blue-green stains on your patches, which could otherwise be misinterpreted as false positive indications of copper fouling. Consequently, you can accurately determine when your bore is genuinely free of copper.
