What is the BROWNELLS - 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.


SPECS:
  • J-B: 2 oz. (57 g) net contents jar.
  • Kroil: 8 fl.oz (237 ml) can.

It really works well !
I've used JB bore paste and Kroil as directed on two ALREADY cleaned 308 rifles which I thought I thoroughly cleaned before. After letting the Kroil set overnight and running a couple of patches of JB paste through I was still finding some carbon and copper on the patches. I don't know if it was this product or just a good day at the range but the Savage Mod.10 shot some impressive groups at 300 & 400 yards. I'll definitely keep using this product.

Best combo for bare metal cleaning
The combination of Kroil & JB to remove copper fouling in my rifles is one of the best combinations available. After running a borescope down my rifle I would say 99% of the carbon and copper fouling are gone. Great combination for getting your barrel back to baseline/factory clean.

Great for Carbon Ring
I ordered this to remove a carbon ring that snuck up on me in the throat of my bolt gun. Took a little effort but it did what regular solvents and cleaners couldnt do. I will continue to use it periodically to make sure the carbon ring doesnt come back.
