I'm currently running a comp M4S. I have not had a chance to shoot it at "longer" distances, yet, though.
As a civilian, 0-300 yards is my main concern, with maximum emphasis on 0-25 yards. 0-25 yards is the most likely distance that someone will assault me from. 25-300 yards is the most likely distance I will shoot a deer/hog/whatever from.
I can tag the targets just fine with irons out to 300+, and shoot around 2 MOA at 100 yards with them and M855 using something to brace/rest the rifle against. I doubt a RDS with 2MOA dot will compromise my ability any.
That said, I tried to like the 4X and then 3.5X ACOG's. They just didn't do it at 0-25 yards, the area I place the MOST emphasis on. The 1.5X Mini-Acog I had kicked ***. The only problem was transitional lighting killed things for me, and the green reticle washed out on foliage. Sure, 532nm wavelength is not found in nature, but that reticle isnlt 532nm in ALL lighting, especially shade. So I went with red, and that sucked at night. Very very poor behind a white light.
So, here is what i ended up with. *still waiting on my Form 4 tax-stamp so I can throw the SF 556-212 on there*
