Description

Bore Tech Proof Positive 22cal Rimfire Jag

Bore Tech's unique Proof Positive jags reduce the annoyance of traditional brass jags indicating copper fouling in your bore. Save your rifle from nickel plated and stainless steel jags, which are extremely hard and can damage the barrel. Get rid of the bending and snapping plastic jags that are cheap, flimsy, and inconvenient. When no copper is present in the bore, traditional brass jags contain approximately 60% copper in their composition, resulting in the blue copper fouling hue on your patch. By removing brass, it is possible to identify when a rifle bore is completely copper free, as well as save money on patches, chemicals, and cleaning time.

The Proof Positive jag line is made of a special alloy that is as supple as brass but has a high tensile strength to resist bending and cracking when a tight patch is applied. These jags have been designed to give excellent cleaning and functionality. Each jag is carefully crafted to exacting tolerances to ensure faultless operation and true, concentric pressure on the barrel surface.

Best Suited For

  • .22 LR / rimfire rifles and pistols
  • Precision shooters wanting accurate bore condition feedback
  • Users of copper-removing solvents (e.g. Bore Tech Eliminator)
  • Routine cleaning of:
    • Target rifles
    • Hunting rimfires
    • Competition firearms

The rimfire-specific version includes knurling that allows patches to be either wrapped or pierced, depending on user preference.

When To Use It

Use this jag during:

  • Standard bore cleaning sessions
  • After shooting sessions to remove:
    • Carbon fouling
    • Lead deposits (common in rimfire ammo)
  • When verifying a barrel is truly copper-free (no false blue staining)
  • With patch-and-solvent cleaning methods

It is especially useful when using copper solvents, as traditional brass jags can give misleading blue stains even when no copper fouling exists.

  • Reduces wasted patches and solvent

FAQs

Why not use a brass jag?
Brass contains copper, which reacts with copper solvents and produces false “blue” fouling indications.

Can I use it for .223 / 5.56?
Yes, but rimfire jags are optimised for .22 LR dimensions. Centerfire-specific jags may provide a tighter fit.

What’s the difference between rimfire and centerfire jags?
The rimfire version has knurling for patch wrapping, while centerfire versions use pointed tips for patch piercing.

Is it safe for my barrel?
Yes, the alloy is designed to be as soft as brass and 100% barrel safe.
