Brownells J-B Bore Cleaning Compound, 2 oz Jar Pack of 12

The original, time-tested formula developed by Jim Brobst and produced under an exclusive license, J-B, has effectively removed burned-on, caked-in powder residue and copper jacket fouling from gun barrels since the 1960s, without causing any damage to the rifling. Today, J-B continues to demonstrate its effectiveness by effortlessly cleaning even the most moly-fouled barrels. Its unique combination of ingredients and a proprietary multi-step mixing process endow J-B with its distinctive properties. These components work in unison to cushion the abrasive action; the soft paste liquefies during use and can be easily wiped from the bore. The non-embedding feature ensures that no abrasive residue remains, preventing further abrasion after cleaning. J-B has long been a staple on gunsmiths' benches, serving as a magic solution for firearms that just won't shoot anymore. These professionals recognize that a thorough cleaning with J-B often restores accuracy. Match and varmint shooters, who frequently fire rounds using moly-coated bullets, face significant copper fouling and burned-in moly, which can complicate cleaning; J-B efficiently addresses these issues. When used with the Lewis Lead Remover, J-B effectively eliminates the last traces of leading from pistol bores. Shotguns, which accumulate lead, powder and plastic fouling, can experience disrupted patterns; J-B swiftly and effectively cleans them. Esteemed figures in the shooting industry have praised J-B. Jim Carmichel, a gun writer and dedicated shooter, stated, I have used J-B for years and routinely use it even on my very finest benchrest rifles. When no other bore cleaner will get the job done, J-B will. The late Warren Page, a benchrest shooting legend, lauded J-B upon its introduction to the shooting community, describing it as an ultra-mild, abrasive oil paste, finer than jewelers' rouge, which effectively addresses metal fouling and severe powder fouling that solvents cannot tackle or require significant effort to remove. He noted that such an extremely fine abrasive, used with discretion, would take out caked powder residue and mild metal streaking without ruining the bore. Utilize the JB compound in conjunction with the Lewis lead remover to meticulously eliminate residual lead deposits from firearm bores, ensuring optimal barrel cleanliness and performance Shotguns accumulate lead, powder and plastic fouling, significantly disrupting shot patterns, J-B effectively and efficiently removes all residues, restoring optimal performance
