- Bore cleaning compound

- Removes powder residue & copper fouling
- Will not damage rifling
A unique combination of ingredients and a one-of-kind, multi-step mixing process give J-B its special characteristics. They work together to cushion the abrasive action; the soft paste liquifies as you use it, then wipes out of the bore easily. The non-embedding feature means there's no abrasive residue left behind which might keep "cutting" after you've finished cleaning.
