KG-12 Copper Solvent$18.00
KG-12 is a "copper specific" non-ammonia solvent which we have been special ordering for some of the European benchrest shooters for several years. Quite a few shooters have picked up a bottle to try at the Supershoot and have come back for another bottle saying how well they felt the KG-12 worked on copper fouling barrels. Evidently the Europeans were right! This is a water based product with no ammonia and no strong odor.
Instructions say to wet the bore with two patches wetted with KG-12, soak for 30 seconds (not minutes, but longer soaking won't harm the bore), check for copper wash just below the crown, finish cleaning in your normal manner. KG-12 will not turn patches blue. 4 oz. bottle with a nice applicator spout.
