Bore Tech’s revolutionary PROOF-POSITIVE jags eliminate the annoying false indication of copper fouling in your bore caused by traditional brass jags. Using a proprietary alloy and secondary treatment process, the new Proof-Positive jags are:

  • 100% Barrel Safe
  • 100% Brass Free

  • 100% Chemically Resistant

  • 100% Heavy Duty

Save your gun from the extremely hard and barrel damaging nickel plated and stainless steel jags. Rid yourself of the cheap, flimsy and frustrating plastic jags that bend and snap.

Traditional brass jags contain over 60% copper in their composition resulting in the blue copper fouling colour on your patch when no copper is present in the bore. By eliminating brass one can effectively determine when a rifle bore is truly copper free and reduce wasted patches, chemical and cleaning time.
