Brownells J-B Bore Cleaing Compound 2Oz 12 Pack
J-B Bore Cleaning Compound has been the go-to solution for shooters and gunsmiths since the 1960s, and this 12-pack of 2 oz tubes puts a proven bore cleaner within reach when you need it most. Whether you're dealing with stubborn copper fouling, burned-on powder residue, or moly-coated bullet buildup, J-B's unique formula tackles fouling that solvents alone won't budge—without damaging your rifling in the process. The soft paste liquifies as you work it through the bore, then wipes out cleanly, leaving no abrasive residue behind to keep cutting after you're done.
Competitive shooters, varmint hunters, and match riflemen rely on J-B to restore accuracy when barrels get fouled from high round counts and specialized ammunition. The formula works equally well on shotguns (cutting through lead, powder, and plastic fouling) and rimfire rifles. Many respect the compound enough to use it on their finest benchrest guns when nothing else gets the job done. The multi-step mixing process creates a unique balance: abrasive enough to cut serious fouling, gentle enough to preserve bore integrity.
A 12-pack means you can keep J-B on your cleaning bench, in your range bag, and at your gunsmith station without running dry between orders. Each 2 oz tube covers plenty of bore cleaning before you'll need to reload. Pair it with a proper bore guide and patches, and you've got a proven system for getting your barrel back to shootable condition.
