Forcing Cone Flex HoneA(R) - 12 Gauge Fine Flex Hone

The finishing touch for forcing cones cut with Long Forcing Cone Reamers. Taper matches perfectly so the maximum amount of abrasive media contacts the barrel's surface for faster, more effective polishing action, with less elbow grease and work. Must be used with Flex Hone Oil; use of other oils will destroy the abrasive balls and void the guarantee.
