I have a sig 3X micro that I don’t hate. Eye relief is just okay, but it feels like it has a lot of space for your eye.
I have an old aimpoint pineapple that I don’t think the glass is quite as good in, but I vastly prefer the shape of it for easier of grabbing/flipping (both in Unity FTC mounts.
If I could have the sig glass in a longer tube or different shape, I would be very happy, but I don’t use the magnifier all that much, so I am kind of prioritizing ease of use over actual quality.
