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.

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.
Additional Product Information – Bore Tech Proof Positive
Patch Jag .338 Cal
Maintaining a .338 calibre rifle requires dependable
cleaning tools that can handle larger bore diameters while still delivering
precise results. The Bore Tech Proof Positive Patch Jag .338 Cal is designed to
provide consistent, effective bore cleaning, helping to remove fouling while
preserving barrel condition.
A properly fitted patch jag ensures that cleaning patches
maintain firm contact with the bore surface. This allows solvents to break down
carbon and copper fouling more efficiently, reducing the number of cleaning
passes needed and improving overall maintenance performance.
Designed for Larger Calibre Efficiency
With larger calibres like .338, achieving even pressure
across the bore is essential. This patch jag is engineered to hold patches
securely and distribute pressure evenly, helping to ensure that fouling is
removed consistently throughout the barrel.
The result is a smoother, more controlled cleaning process
that supports long-term rifle accuracy and reliability.
Accurate Cleaning with Non-Reactive Materials
This jag is constructed from a material that does not react
with copper-based cleaning solvents. This prevents misleading residue during
cleaning, allowing you to accurately determine when your barrel is free from
fouling.
This is particularly beneficial for shooters who rely on
precise cleaning feedback to maintain performance and avoid over-cleaning.
Key Benefits
- Designed
specifically for .338 calibre rifles
- Promotes
even patch-to-bore contact
- Supports
efficient fouling removal
- Helps
maintain accuracy and barrel longevity
- Strong,
durable construction for repeated use
Essential for Consistent Rifle Maintenance
Whether you're cleaning after a range session or preparing
your rifle for storage, using a calibre-specific patch jag helps ensure a more
effective and controlled cleaning routine.
For best results, use alongside quality cleaning rods,
patches, and bore solvents to create a complete rifle maintenance system.
