Brownells 20 Gauge Fine Flex Hone

The final step in refining forcing cones cut with long forcing cone reamers involves using a taper that precisely matches the cone. This ensures that the maximum amount of abrasive media contacts the barrel's surface, resulting in faster and more efficient polishing with reduced manual effort. It is imperative to use Flex Hone oil exclusively, as the use of alternative oils will damage the abrasive balls and void the warranty.
