J-B Bore Paste Gun Cleaner 1/4 oz Jar

The legendary bore cleaner trusted by benchrest shooters, gunsmiths, and serious marksmen for over 60 years.

• Made in the USA
• Ultra-mild abrasive formula to bore fouling - developed by Jim Brobst 
• Liquifies during use for easy wipe-out - no embedded residue
• Restores accuracy in barrels “that just won’t shoot anymore”
• Removes carbon, copper, lead, moly, and plastic fouling
• Safe for even the finest rifle barrels

J-B® Bore Paste has been the go-to solution for stubborn fouling since the 1960s. Its unique blend and multi-step mixing process cushion the abrasive action, making it tough on residue but gentle on rifling. Whether you're cleaning moly-coated match barrels, leaded pistol bores, or fouled shotgun tubes, J-B gets the job done fast.

Used with the Lewis Lead Remover, it’s the final word in lead removal. And when solvents fall short, shooters like Jim Carmichel and Warren Page have long turned to J-B as the cleaner of last resort and first choice.

Size: ¼ oz (7 g) jar
