Bore Tech
The Bore Tech Shotgun Jags for 12 Gauge are engineered to tackle the unique cleaning demands of shotgun barrels. Unlike simple flat patches, these jags feature a hard nylon center tip surrounded by flexible fingers that conform to your barrel's bore and force the patch directly against the walls—the geometry that makes shotgun cleaning actually effective. If you run a 12-gauge smoothbore and want to scrub out powder residue, shot debris, and fouling without fighting your cleaning rod, these work with any standard shotgun cleaning rod you already own.
Shotgun bores are larger and more varied in dimension than rifle bores, which means generic patches often fall short. The finger design on these jags solves that: the flexible tines flex outward under patch tension, keeping maximum surface contact from the choke to the breech. That matters if you shoot enough to care about barrel condition—whether you're running pump guns, semi-autos, or over-unders at the range or in the field.
Threading is male 5/16-27, the standard you'll find on most shotgun rod tips. If you're building a cleaning kit from scratch or upgrading from whatever came in that old plastic case, these jags are a straightforward way to improve your shotgun maintenance without replacing your rod.
| Gauge | 12 Gauge |
| Thread Type | Male 5/16-27 |
| Compatibility | Standard shotgun cleaning rods |
Yes, if your rod accepts standard male 5/16-27 threaded tips—the common thread on most shotgun cleaning rods. Check your rod's tip compatibility if you're unsure.
The flexible fingers push the patch against the barrel walls as you work the rod, ensuring the patch actually scrubs the bore instead of just passing through it. That contact is what removes fouling effectively.
These are designed for 12-gauge bores. Bore Tech makes jags for other gauges; verify the correct size for your shotgun.
The jag is designed to work with standard shotgun cleaning patches that fit the 12-gauge bore; your cleaning kit documentation or rod manufacturer will specify the right patch dimensions.
