Clear lens covers for Aimpoint 5000?

[john l]

Does anyone know where I could get a set of clear lens covers for my aimpoint 5000? I have the black flip-ups now, but I prefer clear ones to use in crappy weather, or just dry firing at home or whenever.
I tried looking up their website, but www.aimpointusa.com doesn't work--and that is the webpage on their box that the sight came in.
Thanks,
