Learn how to convert your traditional speargun into a roller speargun. I flew to Kauai to meet up with Brian Fern (unkolearnuhow) to convert my Meandros speargun b28 to a MannySub ceramic roller speargun muzzle. Full breakdown here: https://castandspear.com/roller-speargun-conversion/
We even did a roller speargun test before taking it out to catch uku on the reef. I must say, this roller speargun conversion kit was easy and effective.
