I currently have an EoTech 512 (the AA battery type) mounted on mine, and like it. The reasoning behind going for the AA, was in a SHTF scenario, those batteries would be hopefully more available. I love the open sight pattern from it.
Having said all that, yeah, I wouldn’t mind a nice scope too (like the combo posted above). But this AR was destined for sport shooting, and CQB, if it ever came...
Solid copy on the 512 and AA batteries...
Hard not to like 7-11 resupply!
