J-B® Bore Compound & Kroil - J-B Bore Compound & Kroil Kit

Save money on the do-it-all combination that's been written up in several of the ''''accuracy'''' publications: J-B and Kroil! Run a couple of patches soaked in Kroil through the bore to get under and loosen barrel fouling, then wipe away most of the crud with a dry patch. Follow with J-B Compound to dig deep and remove the most stubborn moly residue, powder, and copper jacket fouling. A final pass with Kroil coats the bore with a rust preventive film. Mfg: Brownells SPECS: J-B - 2 oz. (57 g) net contents jar. Kroil - 8 fl.oz (237 ml) can.
