Although the selection is limited, aftermarket shafts are available. I had a predator 314 for mine that would also fit a 3/16 x 18 pin. I like my Viking Siege and for a little over $200, the Vikore. There are definitely many shafts that are unavailable with the Viking joint, though.I think it's a giveaway butt. Vikings are not collectable. And with that pin, there are no/few aftermarket shafts that will fit.
