Take a modern bore solvent and squirt it on a brass cleaning jag. The liquid will turn blue as it drips off the jag – it’s working so fast, it starts to dissolve your cleaning jag in front of your eyes! If you’re following conventional wisdom “clean until you get a clear patch” you might be in for a long night. Tipton’s® Ultra Jags™ feature a patent-pending technology that covers the surface of a traditional push-type jag with solvent-proof material, keeping aggressive modern bore solvents from creating false blue stains that normally indicate copper fouling. Before Ultra Jags, these false blue stains caused users to over-clean their barrels – and that’s been emonstrated to destroy accuracy over time. When you use Ultra Jags™, you’ll get better, faster cleaning results because you’ll know you’re getting blue stains from copper fouling from your barrel and not from the surface of your jag. In addition , you will increase the life of your jag by protecting the jags brass core from the aggressive modern solvents with the nickel-plated coating.
