The black ring with the horizontal post on it has teeth on the bottom that make the adjustment happen so you can't really do anything there. There is not enough movement upward for one post to pass over the other in one turn. I can't see any way around it other than removing the zero stop verticle post completely which is easy to do.
As already mentioned by kcebcj, probably just deal with the 16.5 moa and retain the zero stop, remove the post and have no zero stop or just buy another product. I personally like the huskemaw
the best out of any hunting scope I own or have seen but with the latest price increase I won't be buying any more of them. If you need a zero stop with no limit on the top I would recommend a Viper HS LR for much less money and call it good.
