So, though I have a scopecoat for my EOTech, I was looking at their options for the Aimpoint Magnifier and did not find the ideal match/fit. I even called them and they recomended one that should work, but it is not made for it, especially with a quick release mount attached,
So, when fumbling around in my camping gear, I came across this device (available at any REI and most camping stores) I forogot I had.
it is a neoprene cover for a collapsable candle lantern for backpacking. it seems like about the perfect dimensions, and opens in half at the center so you can put in the Magnifier and close it like a book and cover around it.
They are cheap 8$ or so and seem like a good alternative.
