A Favorite Cleaning Secret of Shooters Who Demand Ultimate Accuracy
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.

No-Brush Foam Cleans Fast
Brushless bore-cleaning foam dissolves carbon, copper, brass, bronze, black powder, and smokeless powder fouling. Foam suspends and absorbs the fouling for superb cleaning. Contains corrosion inhibitors so you can leave the cleaner in the bore for up to 24 hours. Won’t harm modern gunstock finishes, carbon steel, or stainless steel; contains no acid or ammonia.
