On a general purpose AR I prefer to have true 1x illuminated reticle w/ ability to add magnification. I use Trijicon accupoint 1x4 which has both fo and tritium illumination w/ the green triangle post. On 1x it is bright and fast and on 4x allows pretty good target ID to 400 yards. It is pretty handy for coyotes too. There are units available now of equal quality and more magnification and more useful reticles. A variable w/ true 1x is ideal for a general purpose AR IMO.
