I'm looking at the dimensions of the Fury HD 5000 AB and Vortex has it listed as 5.8" x 5". The Marsupial no-mag ID is listed at 6" W x 2.75" D x MAX HEIGHT OF 8.25". I can't imagine the Fury won't fit. I can stuff my EL Range TA 10x42 into the Marsupial Gear and that's with the forehead rest. It's a bulky beast, but I can get it in there. The Fury should be less of an issue.
That being said, I recently got the new Stone Glacier Sentinel. It doesn't have the same type of padding as a Marsupial, but it's significantly lighter (~10 oz vs 1lb, respectively). I haven't had much time with it, but I like the design and features.
