JB Bore Cleaning Compound

JB Bore Cleaning Compound

JB Bore Cleaning Compound (2 oz) is the original, time-proven formula developed by Jim Brobst and produced under exclusive license by Brownells. J-B has been getting burned-on, caked-in powder residue and copper jacket fouling out of gun barrels since the 1960’s, and hasn’t damaged an inch of rifling yet. Today, J-B once again proves itself a champion by the way it easily cleans the dirtiest, moly-fouled barrels.
