Brownells 12 Gauge Fine Chamber Flex Hone, Light Blue

The system utilizes numerous abrasive balls mounted on a flexible shaft, providing an efficient and rapid method for cleaning and polishing older barrels or achieving a mirror-like finish on new ones. For used barrels, employing the Fine hone, followed by the Fine, effectively eliminates rough and tight spots, resulting in a bright bore finish that is both visible and tangible. It is recommended to run a patch through the barrel before and after honing to observe the significant improvement. During the honing process, tight spots can be detected and addressed with additional attention until they are smoothed out. For new barrels, using the Fine hone alone enhances the factory finish to a stunning, mirror-bright appearance that is sure to satisfy customers. The process is straightforward - secure the hone in a variable speed electric drill, apply Flex Hone oil to the hone, start the drill and insert the hone into the barrel from the breech end, if feasible. As the hone operates, a slurry of abrasive and oil forms, facilitating the cutting action. Fine grit refers to 800 grit aluminum oxide Fine chamber Flex-Hone with light blue tip
