-B BORE CLEANING COMPOUND Cuts Through Toughest Bullet Jacket & Powder Fouling - Can't-Run Paste Formulation - Cushioned Abrasive Action Leaves Bores Sparkling - Won't "Eat" Stock Finishes. 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 roves itself a champion by the way it easily cleans the dirtiest, moly-fouled barrels. 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. J-B has been a favorite on gunsmiths’ benches for years, as a "magic" cure for customer guns that "...just won’t shoot anymore". These pros know that a good scrubbing with J-B often restores accuracy. Match and varmint shooters put a lot of rounds down range, many of those using moly coated bullets. The large amounts of copper fouling and the burned-in moly can create a cleaning nightmare; J-B makes short work of it. Use J-B with the Lewis Lead Remover to get the last speck of leading out of pistol bores. Shotguns combine lead, powder and plastic fouling to really throw patterns off; J-B cleans it all out quickly and easily.

Great for older rifles.
This stuff really rejuvenates older rifles. I like to refinish-fix up old rifles. Many of these have been in a closet for 50 years and weren't cleaned the the 20 or 30 years before that! A single cleaning with JB results in a shiny bore and better accuracy in each rifle I've tried it on.

It works,it's labor intensive.
This is for when you think you have gotten the barrel clean.. this will make you think again, the final outcome is like a mirror.

Works on hard carbon
I have a MSR approaching 10K rounds. Patches were coming out very faint gray. It was as clean as Hoppes and a brush would get it. Borescope showed carbon still in the grooves. Kroil soaked patch with JB wrapped around a brush, first patch came out black. 10 passes, repeated 5X with a new patch, bore is clean to bare metal, except inside some fire cracking. Pleased with the results, but haven't had time to shoot it.
