Bore Tech’s innovative Proof-Positive Pistol Patch Jags eliminate the annoying false indication of copper fouling that is common with all traditional brass jags when using copper removing cleaners.

All Proof-Positive Pistol Patch Jags feature a proprietary alloy and secondary treatment process, making them 100% brass free and 100% barrel safe. This alloy is as soft as brass but boasts an exceptional tensile strength to prevent bending and snapping under the force of a tight patch.

Traditional brass patch jags are over 60% copper in their composition. When using effective copper removing cleaners this results in a blue copper fouling color on your patches when no copper is present in the bore. By eliminating brass accessories, shooters can effectively determine when a rifle bore is truly copper free and reduce wasted patches, chemical and time.

  Each Proof-Positive Pistol Patch Jag is precision machined to strict tolerances in order to work flawlessly and provide true, concentric pressure on the barrel surface. 

Our Proof-Positive Pistol Patch Jags prevent damage to the firearm’s crown when pulling the rod back into the bore by utilizing a completely smooth, edge free transition between the jag and rod when used with either our Proof-Positive Bore Stix or V-Stix cleaning rods.

Finally an answer to your question, “Is my barrel clean”?
Yes, it is PROOF-POSTIVE clean!

Q: Why are my patches so tight and getting jammed in the bore?

A: There are many factors that can lead to this issue. Presuming that you are using the correct caliber jag and patch size for your application (Please consult our Patch Selection Chart) there is a simple trick to avoid this issue. A commonly overlooked solution to remedy overly tight or jammed patches is what we call “Side Spiking”. Please see our Side Spiking article located in the Knowledge Center for detailed information.

Q: Should I use an undersized jag?

A: We typically do not recommend using undersized jags. We have designed and tested our jags to ensure they work properly in their respective calibers when using the correct size Bore Tech X-Count patches.

Q: What do I clean my jags with after use?

A: When using Bore Tech Cleaners, simply use warm water. We recommend rubbing the jags between your palms while warm tap water flows over them.

Q: What thread sizes are your jags and are they male or female ended?

A: All Bore Tech jags are male ended and have the thread pitch listed under the Specifications Tab on the respective product page.

Q: Why do my patches always turn blue when using Eliminator Bore Cleaner?

A: Eliminator or any other cleaner that is designed to remove copper fouling will attack all brass jags and remove the copper within the jag. To avoid this false indication of copper fouling in the bore, we recommend using our Proof-Positive Jags with all copper removing cleaners.

Q: Do I have to unscrew my jag before pulling my rod back through the bore to prevent damage?

A: A crown is not compromised nor accuracy affected by pulling a properly designed jag back through the bore. We take great care during our design process to make sure our jags have a flush, edge free transition when used in conjunction with the correct Bore Tech cleaning rod. Again, when used with the correct rod and in a proper manner our jags are 100% barrel safe.

Q: Are the Proof-Positive jags barrel safe?

A: All Proof-Positive Patch Jags feature a proprietary alloy that is as soft as brass and100% barrel safe.

Great JAGs! 5 of 5 stars

If you have brass JAGs, you need these Proof Positive JAGs for Pistol and Rifle! (If you have stainless steel JAGs you're probably okay.) These eliminate the Blue-green patches when cleaning for copper fouling, so you know you're making progress. Couple these with their ELIMINATOR bore cleaner and follow the directions. You WILL be happy with the results!

No more false blue patches 5 of 5 stars

I purchased this jag, and used it for the first time. What a game changer, no more false readings. I wish I would have found this product sooner. It saves time and cleaning solution!

Keeps your crown unharmed 5 of 5 stars

If you care about your barrel's crown, this is, by far, the best jag out there. Unlike others, the base of this jag is larger than the patch end and the length of the shank is just right. When a correctly positioned rod stop is used, the patch exits the barrel and drops off, while neither the edge of the jag's base nor the jag's lips can touch the barrel's crown as it is withdrawn. This jag has enabled my 6.5/284 barrel to continue shooting X's after more than 2600 rounds!
