DealKano Kroil Penetrating Oil and Bore Cleaning Solvent is the oil that creeps. Kroil is used by the most accuracy-obsessed benchrest shooters to keep their barrels clean. Kroil creeps below the fouling in your barrel, allowing you to knock it out easily with a patch or brush. For best results when working with rusted or frozen gun parts, allow 24 hours for Kroil to penetrate. from Midway USA (Product 137203) |
