Unfortunately not a lot of people making long eye relief (LER) scopes presently, especially illumimated ones. I went with the leupold VX-R 1.5-5x scout scope on mine. Despite all the shit talk you will see on here, Leupold still makes good scopes IMO. Two things to be aware of, 1 the eye relief is a touch short for a LER scope but it's still usable and 2 the illumination isn't really daylight bright. It isn't bad but I wish it was brighter, a perfect comparison is the 1-4x nightforce nxs illumination. I would recommend this scope as it fits into the specifications you listed, but those are the main drawbacks I have observed. Also keep in mind you will probably want to get a stock pad that has some built in elevation into it like the TNVC one or just build your own, otherwise you will probably end up doing an AK style cheek weld to get good head placement.
