I am going to either build or buy a Sig 556 SBR. I want optics for it. I also want optics that I can use on my AK and benelli M4. I would prefer to get one optic that will work on all. I really like the aim point micro but dont like how small the dot is when compared to Eotech. Is the aimpoint micro a 1 MOA at 100 yards? Would the eotech or aimpoint be quicker for cqb? Which one would shoot better at longer ranges? I like the Eotech but dont like the battery life. The EOTECH seems much faster. Not sure if aimpoint makes an optics with a larger than micro red dot? Not sure if the eotech would be good at long range since it is so large of a circle. Whats the max range of each without magnifiers?
