Our 50 caliber patch jag is designed specifically for cleaning 50 caliber muzzleloader barrels. These jags should only be used in guns with removable breech plugs. They may work in other muzzleloaders, but it is sometimes difficult to reverse direction with this jag, especially if the barrel is rough or pitted, and this makes it difficult or impossible to remove this jag from a muzzleloader that does not have a removable breech plug. These patch jags press a patch that has been treated with solvent or bore paste against the barrel and into the rifling to mechanically strip the carbon, plastic, and copper out of the bore. We used this patch with no solvent for demonstration purposes, and pushed it through the barrel once. As you can see, these Jags clean better than any other jag on the market. “The proof is on the patch”. In addition to cleaning, our jags are also used for oiling the bore for storage as well as removing oil before firing. Our rifle jags fit all rods with standard 10x32 threads. Note: Two versions of this jag were produced. Due to machining and tooling considerations, the design was changed from aluminum to brass, and the body of the jag was tapered.

In addition to this product, we suggest you purchase USP Bore Paste and round TCS patches for Shotguns. TCS round patches are the perfect size for use with this jag, and other patches may cause fit problems. Square patches should not be used with our jags..
