Who makes one?
I got one from Brice Hensley he's on facebook. I'm pretty sure warbird on here makes them and Brice sells them
Dreamland Plastics. Google them or look on Amazon. They are the best cover I have seen for the Burris ff's and the Vortex.
Ridge Rooster
gobbler 74 (I think) warbird has one to fit on top of base. We have on that fits with out base.
