Bore Tech’s innovative Proof-Positive Rifle Patch Jags
eliminate the false indication of copper fouling that is common with all
traditional brass jags when using copper removing cleaners.
Constructed from a proprietary alloy and engineered to
provide superior cleaning, these jags set the standard for effective,
non-brass, 100% barrel safe jags. Are your barrels PROOF-POSTIVE clean?
Bore Tech’s innovative Proof-Positive Rifle 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 Rifle 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.
TRADITIONAL BRASS PRODUCTS
PROOF-POSITIVE PRODUCTS
Featuring a dual set of 4 contact rings* for added patch
contact and cleaning, the Proof-Positive Rifle Patch Jags are precision
machined to strict tolerances in order to work flawlessly and provide true,
concentric pressure on the barrel surface. The first ring of each set is
rounded in order to allow the jag to center itself in the chamber/bore and
alleviates the possibility of damage. The three subsequent rings of each set
have a squared face that grabs the patch keeping it in place. In addition, the
relief space between the dual set of rings acts as an extra solvent reservoir
by retaining clean/unused solvent and dispensing it before the second set of
rings passes. Each jag length is specifically determined based on the caliber
and proper patch size necessary for cleaning. This prevents patches from
bunching and jamming on the tip of the cleaning rod.
Each Proof-Positive Rifle Patch Jag features a reverse taper
at the rear of the jag that provides a completely smooth, edge-free transition
between the jag and rod when used with our Proof-Positive Bore Stix cleaning
rods. The reverse taper prevents damage to the firearm’s crown by centering the
jag and lifting the cleaning rod off the bottom of the barrel when pulling the
rod back into the bore.
Finally an answer to your question, “Is my barrel clean”?
Yes, it is PROOF-POSTIVE clean!
FAQ
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.
Q: What is the difference between the 22 Rimfire and
22Centerfire Jags?
A: The 22 Rimfire jag has 2 bands of knurling instead of the
two bands of rings at the head of the jag. Many Rimfire shooters like to wrap
patches around the jag instead of spiking them. The knurling allows the shooter
to choose between wrapping and spiking the patch. Both jags can be used on
either 22 rimfire or centerfire barrels.
Extended Product Information – Bore Tech Proof Positive
Patch Jag .17 Cal
For shooters using .17 calibre rifles, maintaining a clean
and consistent bore is essential for preserving accuracy and performance. The
Bore Tech Proof Positive Patch Jag .17 Cal is specifically designed to support
high-precision cleaning routines, ensuring that even the smallest calibre
barrels receive thorough and reliable care.
The compact bore diameter of .17 calibre rifles makes proper
cleaning tools even more important. A correctly fitted patch jag like this one
allows cleaning patches to maintain full contact with the internal surface of
the barrel, helping to remove fouling efficiently without excessive passes.
This not only improves cleaning effectiveness but also reduces unnecessary wear
on both the barrel and cleaning equipment.
Optimised for .17 Calibre Rifle Maintenance
Using a calibre-specific jag ensures that your cleaning
process is both effective and controlled. The Bore Tech Proof Positive Patch
Jag is engineered to deliver a balanced fit, preventing loose patches that fail
to clean properly or overly tight patches that can cause resistance during use.
Its non-reactive construction also plays a key role in
modern bore cleaning. When using copper-removing solvents, traditional
materials can sometimes produce misleading residue. This jag avoids that issue,
giving you a more accurate indication of when your barrel is truly clean.
Key Advantages for Shooters
- Supports
precise bore cleaning for .17 calibre rifles
- Helps
maintain consistent shooting accuracy
- Reduces
the need for repeated cleaning passes
- Works
effectively with a wide range of cleaning solvents
- Ideal
for both routine maintenance and deep cleaning sessions
Essential Tool for Small Calibre Precision
Whether you’re shooting for accuracy at the range or
maintaining a hunting rifle, proper bore care is critical—especially with
smaller calibres like .17. The right cleaning jag helps ensure your rifle
continues to perform reliably shot after shot.
Adding a high-quality patch jag to your cleaning kit is a
simple but important step toward better firearm maintenance and long-term
performance.
Improve Your Cleaning Setup
Pair this .17 calibre patch jag with quality cleaning rods,
patches, and bore solvents to create a complete and effective maintenance
