I'm told that this is likely impossible to do without significant parallax issues that are less noticeable on handguns, but can be more readily seen when shooting longer distances with long guns. EOTechs being a HWS get away from this issue due to being able to project on multiple planes, while RDSes are inherently single plane. Or so I was told.
What do you mean by "do it"? I'm not disputing that putting in the ring reticle is totally doable (I know the MRO HD also has the circle, and I remember using multiple reticles back in my old NcSTAR airsofting days), but the question is more of how much utility does that ring give for long guns, given the alleged parallax issue, and whether the pros outweight the cons. Though I'll stress again that this is simply what I've read from a relatively reputable source, and am not stating that it is an absolute fact I know for sure.

For users who mostly use carbines at room and < 25 yard distances and moving targets, the ring reticle has considerable utility.
Given some of the users running 4M's (FBI) and 4Ts (DHS/ICE and UK SAS among others) I would expect to hear about parallax issues if they were significant but I can ask around. The 4Ts are still fairly new but the 4Ms have been is use for several years and the only complaints I'm aware of on the 4M's are cheap mounts failing and random electrical failures killing some of the sights.
I'm a poor civilian not FBI, but I did have a random electronics failure on a Romeo 4M a few years ago and haven't bought a Sig optic since. One quarter of the segmented circle reticle just stopped working. That same weekend my brothers Romeo 4B completely died after some light rain. Sig replaced both, but both new units went to ebay as soon as they arrived...
That matches the random electrical failures mentioned above. The 4M was something of an odd duck because at least the government supplied ones were imported as parts kits and assembled by a third-party vendor in the US to comply with the letter, if not the spirit of some federal acquisition rules.
