I'd go back to your optometrist and have him fix your correction.

I am hearing that the release dates on new Holosun optics is slipping because of the impact of the Corona virus. I also was told today that the “CO” designation you see on some Holosun optics means “contract overrun.”
i was waiting for a 509t, but i found out it won't be released until at least 5/1.
I ended up getting a v1 508t instead for a decent price.
