KG-12 Big Bore Cleaner Copper Remover

KG-12 was developed specifically to remove the toughest copper fouling without damaging the bore. KG-12 is water based so unlike ammonia-based products, there is no need to neutralize KG-12 or to remove it quickly.

After 30 years of cleaning many guns a day in the gun trade we have tested pretty much all the products on the market and this is the best we have come across for removing Copper.
