Butler Creek Blizzard Covers?

[JHoward]

Anyone running them? I need one for my 30mm Vortex magnifier and there doesn't seem to be an option for 30mm at all, I was just wondering if anyone knew which size I should go to, BC suggests #2, but it's a good bit bigger.

I'm not using the Blizzard covers, but my experience with the BC covers are that they've all been pretty snug. Looking at the product specs here (http://www.vortexoptics.com/product/vortex-vmx-3t-red-dot-magnifier/specs), the outside diameters are 1.3 and 1.36 inches, which matches up with the specs of the #2. Guessing that's what they're basing their recommendation on.
