I recently purchased a Yankee Hills YHM-8810 AR15. So far I have managed fine in accessorizing the gun. But I am really having a tough time picking a good sight. It came with iron sights and co-witnessing would be nice. And I have done enough research to realize that sights really are a case where you get what you pay for. Right now I am primarily looking at options from EOTech and Aimpoint. But I am leaning more toward the EOTech EXPS2-0 with a 3X flip to side magnifier. Of course while reading and researching, I came across another sight, the UltraDot 6. It looks pretty good in the pictures and sounds good in the little I could find on it. But there isn't a whole lot of information out there on it. Could anyone please offer some good advice in recommending one over the other?
