BFR, I guess this one is a brand new product that replaces the Millet zoom dot & is marketed by Bushnell. Optics Planet ois showing them at $209 shipped & says available this month.
Tigger, I found them on Millets site a couple days ago but now that link won't open. In that add they said there was an extreme recoil mount available or in the works that included a tube extender to make it a 2 ring mount.
