Copper Eliminator jags are made from machined aluminum, which does not react with ammonia-based solvents and prevents false positive indications of copper fouling.
These jags are designed to be gentle on the bore and muzzle, with a hardness similar to brass to avoid scratching or damage during cleaning.
The female-threaded jags are compatible with standard Dewey nylon-coated rods, enhancing the cleaning system's benefits for existing equipment.
