J-B Bore Paste

J-B Non-Embedding Bore Cleaning Compound is the original (from the early 1970's) paste bore cleaner developed by Jim Brobst, an accomplished benchrest shooter in the early days of the sport. J-B removes powder, copper jacket, lead and plastic wad fouling from rifle and shotgun bores.

This cleaner has almost no odor, is safe in any barrel, will not embed in barrel steel and is easy to remove from the bore. Lots of today's benchrest shooters say they prefer J-B over Iosso Paste Cleaner because they find it much easier to remove from the barrel when they are through cleaning.

J-B is usually used on a tight-fitting patch and short-stroked through the bore, then a few brush strokes with Butch's or other liquid solvent easily removes the J-B. 2 oz. screw top
